Sodium Hexafluorozirconate, Sodium Zirconium Fluoride

Sodium hexafluorozirconate, also known as sodium zirconium fluoride, is widely used. In the field of metallurgy, it is often used as a flux. It can reduce the melting point of metals, allowing metals to be melted at lower temperatures. As a result, it can save energy, improve metal fluidity, and make the casting process smoother. The quality of the cast metal products is also better and the shape is more accurate.
In the ceramic industry, it can be used as a flux and an opacifier. As a flux, it can reduce the firing temperature of the ceramic body, reduce energy consumption, and promote the densification of the body, improving the mechanical strength and chemical stability of the ceramic. As an opacifier, it can make the ceramic glaze appear milky white and opaque, adding its aesthetics and decoration.
In the electronics industry, sodium zirconium fluoride also has important uses. In the semiconductor manufacturing process, it can be used in the etching process. With its chemical properties, it can precisely remove the unnecessary parts of the semiconductor material, so as to achieve a specific circuit pattern and structure, which has a profound impact on the performance and integration of semiconductor devices.
In addition, in the manufacture of optical materials, it can participate in the preparation of optical glass. The refractive index, dispersion and other optical properties of the glass can be adjusted to meet the special needs of different optical instruments, such as lenses and prisms, for optical performance, making great contributions to the development of the optical field.

Sodium Hexafluorozirconate (Sodium Zirconium Fluoride), that is, Sodium Zirconium Fluoride (Sodium Zirconium Fluoride), the two are different names for the same substance. Its physical and chemical properties are unique and it has important uses in many fields.
This substance is mostly white crystalline powder at room temperature, with a pure appearance and no special color. Its chemical stability is quite good, it is not easy to react with common substances in general environment, and its chemical properties are relatively peaceful. It is insoluble in water, has low solubility in water, and often exists in the form of precipitation or suspended particles in aqueous solution systems. This property makes it easy to separate and recover from the system in industrial processes or chemical experiments involving the aqueous phase.
From the perspective of melting point and boiling point, the melting point of this substance is quite high, and a higher temperature is required to transform it from a solid state to a liquid state, indicating the stability of its structure and the strong force between atoms. The boiling point is also correspondingly high, indicating that it can maintain a relatively stable phase state in a high temperature environment, and it is not easy to be easily vaporized and lost, which is crucial for high-temperature processing or reaction processes, ensuring that its performance is stable under high temperature conditions.
Its density is relatively large, and it is heavier at the same volume than some common light metal salts. This density characteristic is of great significance in the field of material preparation. When high-density and high-strength materials need to be prepared, sodium hexafluorozirconate can be used as an important additive to improve the overall density and mechanical properties of the material.
In addition, sodium hexafluorozirconate has good thermal stability and will not decompose or deteriorate significantly due to temperature changes within a certain temperature range. This allows it to exist and function stably in high-temperature environments, such as metallurgy, ceramics and other high-temperature processing industries, or as a flux to reduce the melting point of certain substances, or as an additive to improve material properties, helping to carry out related industrial processes smoothly.

The method of making sodium hexafluorozirconate (also known as Sodium Zirconium Fluoride) varies from ancient recipe to recipe. Zircon is often the beginning. First, zircon is co-melted with soda ash, and then it is melted. Zircon and soda ash are changed at high temperature to form sodium silicate and sodium zirconate.
It melts and is quenched with water. Sodium silicate is soluble, and sodium remnant zirconate is insoluble, and it is separated. After the phase of sodium zirconate and hydrofluoric acid is combined to produce hexafluorozirconic acid.
Hexafluorozirconic acid is then mixed with sodium salt to obtain sodium hexafluorozirconate. The sodium salt is often sodium chloride. The two are combined in the phase, and the reaction of the complex decomposition in the solution is to precipitate the crystal of sodium hexafluorozirconate.
After the complex decomposition is completed, filter the liquid to obtain the solid of sodium hexafluorozirconate, then wash it with water, remove impurities, and then dry it with warm fire to obtain pure sodium hexafluorozirconate.
There are other ways. Or make the metal zirconium first directly combine with fluorine gas to form zirconium tetrafluoride (ZrF), and the zirconium tetrafluoride is then combined with sodium fluoride to produce sodium hexafluorozirconate. However, fluorine gas is required in this way. Fluorine gas is toxic and active, and it is difficult and dangerous to operate, so it is rarely used.
Or there are zirconium-containing ores, which are enriched by metallurgy to obtain zirconium-rich materials, and then follow the above method to produce sodium hexafluorozirconate. In short, although there are different methods, they all seek to obtain pure products to meet the needs of industry, used in ceramics, glass and other industries, to improve their properties and increase their capabilities.

Sodium (Sodium) and Sodium Hexafluorozirconate (Sodium Zirconium Fluoride) have a number of important precautions when using, and should not be ignored.
One is related to safety protection. Both of these have certain chemical activity, and must be fully protected when in contact. Wear suitable protective clothing to avoid direct contact with the skin to prevent chemical burns. Wear protective eye masks and gloves, because once in contact with the eyes or skin, it may cause serious irritation or even damage. If inadvertently touched, rinse with plenty of water immediately, and seek medical treatment if necessary according to the severity of the injury.
Second, chemical properties are related. Fluorinated compounds such as sodium hexafluorozirconate may release toxic gases such as hydrogen fluoride under specific conditions. Therefore, where it is used, it must be well ventilated to prevent the accumulation of harmful gases and endanger personal safety. At the same time, in view of the abnormal activity of sodium metal, it reacts violently in contact with water, generating hydrogen and releasing a lot of heat, which can easily cause combustion or even explosion. Therefore, when using it, it must be kept away from water sources, and the operating environment must be kept dry. When storing, sodium should be stored in inert liquids such as kerosene to prevent contact with air and moisture.
Third, operating specifications. When using such substances, appropriate tools and methods should be used, and strict operating procedures should be followed. When weighing, strive to be accurate to avoid errors that cause abnormal subsequent reactions. After use, the remaining substances cannot be discarded at will, and must be properly disposed of according to regulations to prevent environmental pollution. And throughout the operation process, always stay focused to prevent accidents caused by negligence. In this way, the process of using sodium and sodium hexafluorozirconate is guaranteed to be smooth, avoid danger, and ensure personal and environmental safety.

Sodium hexafluorozirconate (Sodium Hexafluorozirconate) is Sodium Zirconium Fluoride (Sodium Zirconium Fluoride). The market prospect of this product is quite promising.
