In the electronics industry, they can be used for the etching and cleaning of semiconductor materials. In the precision process of semiconductor manufacturing, ensuring the purity and precision of the material surface has a significant impact on the performance and reliability of electronic components such as chips. Ammonium hydrogen fluoride sheets play an important role in this process.
All of these are the main uses of ammonium hydrogen fluoride sheets and are of great significance in the development of modern industry.
What are the Storage Conditions for Ammonium Bifluoride Flakes?
Ammonium fluoride flakes (Ammonium Bifluoride Flake) are chemical substances, and their storage conditions are very important. This flake should be stored in a cool, dry and well-ventilated place.
A cool place can avoid the harm of high temperature. If it is at high temperature, it may cause chemical changes and damage its quality. Dry place, waterproof and wet. Due to moisture, it is easy to cause deliquescence, which destroys its original state, and may cause chemical changes and lose its usability. Well-ventilated, it can disperse harmful gases that may be generated, so as not to accumulate and cause danger.
It also needs to be separated from reactive substances. If alkali substances meet them, they may react violently and cause danger. And keep away from fire and heat sources, because it may be flammable, and it will be dangerous in case of fire.
The storage device should be made of corrosion-resistant materials. Because of its corrosiveness, ordinary materials are easily corroded, causing the risk of leakage and endangering the surroundings. When taking it, it is also necessary to follow strict procedures to ensure safety and safety. In this way, ammonium fluorohydride sheets must be properly stored to ensure their quality and avoid all kinds of hazards.
What is the Production Process of Ammonium Bifluoride Flake?
The manufacturing process of ammonium (Ammonium) and ammonium hydrogen fluoride (Bifluoride Flake) is an important link in the chemical industry. The method first takes ammonia gas (Ammonia gas) and anhydrous hydrofluoric acid (Anhydrous hydrofluoric acid) as raw materials. In a special reactor, ammonia is slowly introduced into the anhydrous hydrofluoric acid according to the precise ratio. This process requires observing the conditions of temperature and pressure, and usually the temperature is controlled in a specific range, so that the reaction can proceed smoothly.
At the beginning of the reaction, the two combine rapidly. This is a violent exothermic reaction, so a delicate cooling system is required to ensure a smooth reaction and avoid temperature runaway. As the reaction advances, a solution of ammonium hydrogen fluoride is formed. After that, the solution is introduced into the crystallization device, and by means of cooling and concentration, ammonium hydrogen fluoride crystals are precipitated.
The precipitated crystals still contain impurities and need to go through the refining process. The method of recrystallization is often used to improve the purity of ammonium hydrogen fluoride. During recrystallization, the crystals are dissolved in an appropriate amount of solvent, heated to a specific temperature, so that the impurities remain in the mother liquor, and then cooled and filtered to obtain high-purity ammonium hydrogen fluoride crystals.
Finally, the refined crystals are dried to remove the residual moisture to obtain the finished product of ammonium hydrogen fluoride flakes. The whole process requires fine control of the parameters of each link and strict adherence to the operating procedures to obtain high-quality products to meet the needs of many industrial fields.
What are the precautions when using Ammonium Bifluoride Flake
When using Ammonium Bifluoride Flake, there are many things to pay attention to.
First, this material is corrosive and can cause burns when it touches the human body. Therefore, when using it, be sure to wear protective equipment, such as gloves, goggles and protective clothing, to prevent it from coming into contact with the skin and eyes. If you come into contact inadvertently, rinse with plenty of water immediately and seek medical attention as soon as possible.
Second, Ammonium Bifluoride Flake is easy to deliquescent in the air. It should be properly stored in a dry place to prevent moisture and deterioration, which will affect the effectiveness of use.
Third, during its use, harmful gases may be released. The operation should be carried out in a well-ventilated place, preferably in a fume hood to ensure the safety of the working environment and avoid the inhalation of harmful gases into the human body.
Fourth, the dosage should be accurately controlled during use, and added according to specific needs and reaction proportions. Excessive use is not only wasteful, but also may cause the reaction to go out of control and cause adverse consequences.
Fifth, after use, the remaining ammonium hydrogen fluoride flakes should be sealed and stored, and the utensils used should be cleaned in time to prevent residual substances from corroding the utensils or causing environmental pollution. At the same time, waste flakes and cleaning wastewater should be properly disposed of in accordance with relevant regulations, and cannot be discarded or discharged at will. Overall, when using ammonium hydrogen fluoride flakes, it is necessary to strictly follow the operating procedures and pay attention to safety protection and environmental protection in order to ensure the safety of the use process and achieve the desired results.
Ammonium Bifluoride Flakes React with Other Chemicals
Ammonium (Ammonium) and ammonium hydrogen fluoride (Bifluoride Flake) belong to the genus, and may have a reaction change in various chemicals.
Ammonium hydrogen fluoride is acidic and active. If it encounters alkalis, such as sodium hydroxide, it must be neutralized. Hydroxide phase with hydrogen ions in ammonium hydrogen fluoride, raw water and salt, which should be as follows: $NH_ {4} HF_ {2} + OH Na= NaF + NH_ {3}\ cdot H_ {2} O + H_ {2} O $.
If it is a metal oxide, take Copper Oxide as an example, the hydrogen of ammonium hydrogen fluoride and the oxygenation of copper oxide to produce water, and the metal ion and fluoride ion form a salt, which should be about: $CuO + 2NH_ {4} HF_ {2} = CuF_ {2} + 2NH_ {3}\ cdot H_ {2} O $.
Before reducing substances, although fluorine in ammonium hydrogen fluoride is stable, the ammonium root may be variable. In case of strong reducing agents, the nitrogen valence state in the ammonium root may be changed, resulting in different products.
As for ammonium ions, their properties are not constant. In case of strong alkali, ammonium root and hydroxide are radicalized, and ammonia gas (Ammonia Gas) escapes. And in some coordination reactions, ammonium ions can be used as ligands to form complexes with metal ions.
It is important that ammonium hydrogen fluoride and ammonium ions in the field of chemistry, when encountering different substances, often have different reactions, or new compounds, or metavalent states according to their properties, all follow the laws of chemistry.
