Zirconium oxychloride, with the CAS number 7699 - 43 - 6, is a chemical compound. Its chemical formula is ZrOCl₂·8H₂O and it appears as white crystals. The molecular weight of this octahydrate form is approximately 322.25 g/mol. It has good solubility in water and forms an acidic solution. The pH value of its aqueous solution is usually around 1 - 2, which means it is relatively acidic. The melting point of zirconium oxychloride octahydrate is about 100 °C. It loses its water of crystallization upon heating.
Zirconium oxychloride has a wide range of applications in different industries. In the ceramics industry, it is used as an additive to improve the mechanical properties and thermal stability of ceramic products. By adding zirconium oxychloride to the ceramic raw materials, the hardness, toughness, and resistance to thermal shock of the final ceramic products can be significantly enhanced. This is very important for high - performance ceramic products used in areas such as aerospace and automotive industries.
In the chemical industry, zirconium oxychloride serves as a precursor for the synthesis of other zirconium compounds. For example, it can be used to produce zirconium hydroxide, which is further used in the production of catalysts. These catalysts are widely used in chemical reactions, such as the oxidation of organic compounds, due to their high catalytic activity and selectivity.
In the textile industry, zirconium oxychloride can be used as a mordant. It helps the dyes to adhere better to the fabric fibers, resulting in more vivid and long - lasting colors. This is especially useful for natural fibers, such as cotton and wool, to improve the dyeing quality.
When using zirconium oxychloride, first, it should be stored in a cool, dry place away from incompatible substances. Before use, it is necessary to wear appropriate personal protective equipment, such as gloves and goggles, to avoid direct contact with the skin and eyes. When preparing an aqueous solution, add the zirconium oxychloride slowly to water while stirring continuously to ensure uniform dissolution. The concentration of the solution should be adjusted according to the specific application requirements.
If it is used in the ceramics industry, it is usually mixed with other ceramic raw materials in a certain proportion during the preparation of the ceramic body. The mixture should be thoroughly homogenized to ensure the uniform distribution of zirconium oxychloride in the ceramic matrix.
In the chemical synthesis process, the reaction conditions, such as temperature, pressure, and reaction time, should be strictly controlled according to the reaction mechanism and requirements. The appropriate amount of zirconium oxychloride should be added at the right time to ensure the smooth progress of the reaction.
Case 1: Ceramics Manufacturer A. This company produces high - end ceramic tableware. By adding an appropriate amount of zirconium oxychloride to their ceramic raw materials, they have successfully improved the hardness and scratch resistance of the tableware. The tableware can withstand daily use and washing without easily getting scratched or damaged. As a result, the market competitiveness of their products has been significantly enhanced, and they have received more orders from both domestic and international markets.
Case 2: Chemical Company B. This company is engaged in the production of catalysts. They use zirconium oxychloride as a raw material to synthesize zirconium - based catalysts. Through strict control of the synthesis process, the catalysts they produce have high catalytic activity and stability. These catalysts are used in the production of a certain type of plastic, improving the production efficiency and product quality. The company has achieved good economic benefits through the application of these high - performance catalysts.
