What are the main uses of Fluozirconic Acid?
Fluorozirconic acid has a wide range of uses. In the field of metallurgy, it is often used as a metal surface treatment agent. It can help metals form a dense oxide film, increase their corrosion resistance and wear resistance, and make metal utensils durable. Such as smelting copper and iron, through fluorozirconic acid, its surface is strong and can withstand the erosion of wind and rain.
In the ceramic industry, it is also an important raw material. It can adjust the properties of ceramic glaze, making the glaze smooth and bright, with bright colors and durability. When porcelain is fired, fluorozirconic acid is added, and the porcelain comes out of the kiln. It has excellent appearance, fine texture and radiance.
In the preparation of catalysts, fluorozirconic acid is also indispensable. It can be used as an active component or carrier to help chemical reactions proceed efficiently. Many chemical processes rely on its catalytic power to increase the reaction rate, increase the amount of products, and reduce energy consumption.
And in the electronics industry, it is also useful. Such as the etching of semiconductor materials, fluorozirconic acid can accurately etch off excess parts, maintaining the precise structure of electronic components, so that electronic products have excellent performance and stable operation.
What are the precautions for storing Fluozirconic Acid?
Fluorozirconic acid is also a highly corrosive chemical. When storing, all the things to pay attention to must be detailed.
First of all, choose a cool and well-ventilated place. The cover fluorozirconic acid is prone to change when heated. If it is in a high temperature place, or the internal pressure of the container rises, it will eventually break. And well ventilated, it can prevent the accumulation of harmful gases and keep the surrounding air fresh.
Next, the container must be strong and corrosion-resistant. It should be made of special plastic or glass, because metal containers are often easily corroded by fluorozirconic acid, causing leakage. The seal must be tight to prevent moisture, air, etc. from contacting it and causing deterioration.
Furthermore, the storage place should be kept away from fire sources, heat sources and all kinds of flammable and combustible materials. Although fluorozirconic acid is not flammable, in case of fire or hot topic, or toxic fumes, and mixed with flammable materials, etc., or increase the risk factor.
In addition, it needs to be isolated from alkalis, active metal powders, etc. Fluorozirconic acid is acidic, and when it encounters alkalis, it will react violently; it is also easy to react with active metal powders, which can cause accidents.
In addition, the storage place should be clearly marked with warning signs so that everyone is aware of its danger. And complete emergency response equipment and materials are required. If there is a leak, it can be responded to in time to reduce the damage. In daily management, it is necessary to regularly check the condition of the container to ensure the safety of storage.
What are the Physical Properties of Fluozirconic Acid?
The physical properties of fluorozirconic acid are as follows. This acid is often in the form of a colorless solution, with a clear and fluid appearance, like a clear spring, without the disturbance of impurities. Its density is greater than that of normal water, and it feels like a dignified touch.
In terms of its boiling point and melting point, the boiling point is quite high. Under normal pressure, it needs a hot topic to boil, which seems to be tough and cannot be easily vaporized. The melting point also has its specific value. Under suitable low temperatures, it can be condensed into a solid state, like ice jade, but its properties are not as fragile as ice.
The solubility of fluorozirconic acid is quite good in dissolving all kinds of solvents. It can be evenly dispersed in water and form a uniform system, just like sand entering a stream, which is seamless. And the conductivity of its solution is also good. When the current passes through, it is as smooth as a fish swimming in a shallow bottom. This is due to the migration of ions, which are active in the liquid and conduct electric charges, so that the current can flow smoothly.
In addition, its volatility is extremely low. In a normal temperature and humidity environment, it rarely spreads in the air, just like a quiet lake. The waves are as flat as a mirror, and it is difficult to make waves. The smell is weak, and it is almost invisible to ordinary people. It is only when you get close to it and smell it carefully, or you can feel its faint smell, but it is not pungent and intolerable. This kind of physical property is unique in many fields of chemical industry and scientific research, either as a reaction medium or as an auxiliary agent for materials.
What are the effects of Fluozirconic Acids on the environment?
Fluorozirconic acid is a chemical substance. Its impact on the environment cannot be underestimated. If fluorozirconic acid flows into rivers and seas, the organisms in the water will bear the brunt. Fish, shrimp and crabs, etc., may be difficult to survive due to sudden changes in water quality. The fluorine, zirconium and other elements contained in fluorozirconic acid may cause eutrophication of water bodies, algae grow wildly, block sunlight, and underwater organisms are difficult to photosynthesize, resulting in ecological imbalance.
If fluorozirconic acid escapes into the atmosphere, it is also a disaster. The aerosols it forms, if inhaled by humans, damage the respiratory system. And fluoride-containing particles fall on the earth, polluting the soil. Soil fertility is damaged, and vegetation growth is trapped. Plant roots or due to changes in soil chemical properties, it is difficult to absorb nutrients, resulting in withered leaves, stunted growth, or even death.
Furthermore, fluorozirconic acid accumulates in the soil or penetrates into the groundwater layer. Groundwater is an important water source for human and animal drinking and agricultural irrigation. If it is polluted, it will be harmful. Drinking polluted water can cause people to suffer from various diseases, such as dental fluorosis and skeletal fluorosis, which seriously affect their health. Agricultural irrigation uses this water, and the quality of crops is also affected, or the production is reduced and the harvest is lost.
Therefore, the impact of fluorozirconic acid on the environment is extensive and profound, and it needs to be handled with caution to prevent it from ravaging the environment and endangering the survival of all things.
What is the preparation method of Fluozirconic Acid?
For fluozirconic acid (Fluozirconic Acid), the preparation method is particularly important. The method is as follows:
First take an appropriate amount of zircon stone, which is firm and stable, and is often the starting material for the preparation of zirconic compounds. The zircon stone is co-heated with concentrated sulfuric acid. This step requires a special container and precise control of the heat. When zircon stone encounters concentrated sulfuric acid, it is thermally stimulated and undergoes a complex chemical reaction. The zirconium element gradually separates and forms the form of zirconium sulfate.
Then, ammonium fluoride is added to the zirconium sulfate solution. Ammonium fluoride and zirconium sulfate combine, and the reaction is exquisite to form ammonium fluorozirconate and ammonium sulfate. At this time, the solution components are mixed and need to be separated.
The method of crystallization is commonly used to control the temperature and solution concentration, so that ammonium sulfate crystallizes and precipitates first, and the ammonium sulfate crystals are filtered away. The remaining liquid mainly contains ammonium fluorozirconate.
Then the ammonium fluorozirconate liquid is treated, and the pH is adjusted with strong acids such as hydrochloric acid or nitric acid to promote the decomposition of ammonium fluorozirconate, and finally the fluorozirconic acid solution is obtained. After evaporation and concentration, the fluorozirconic acid reaches a suitable concentration before it can be prepared for subsequent use. The whole preparation process requires fine operation at each step, subtle changes in the reaction are observed, and precise control conditions can be used to obtain pure and compatible fluorozirconic acid.
