Yttrium chloride hexahydrate, chemical formula YCl3ยท6H2O, is a yellow or light yellow crystalline powder, soluble in water, also soluble in ethanol and water.
In the preparation process of yttrium chloride hexahydrate, yttrium oxide is usually used to react with hydrochloric acid, and then obtained by filtration, evaporation, crystallization and other steps. Its preparation method is as follows:
1.Yttrium oxide powder is reacted with hydrochloric acid to obtain yttrium chloride solution;
2.The yttrium chloride solution is evaporated to concentrate the solvent yttrium chloride;
3.The concentrated yttrium chloride solution was cooled and crystallized;
4.Crystallized yttrium chloride hexahydrate was collected.
The following points need to be paid attention to in the preparation of yttrium chloride hexahydrate:
1.The purity of the raw materials should be high to ensure the purity of the product;
2.During the evaporation process, the temperature and time should be controlled to prevent the hydrolysis of yttrium chloride solution;
3.When cooling crystallization, the temperature and time should be controlled to ensure that the crystallization is complete;
4.The collected yttrium chloride hexahydrate should be dried in time to prevent moisture absorption.
Yttrium chloride hexahydrate has a wide range of applications, mainly used in the following aspects:
1.As an milky whitening agent for glass, ceramics and enamel, yttrium chloride hexahydrate can change the whiteness and gloss of the product and improve the quality of the product;
2.As a raw material for the manufacture of refractory materials, yttrium chloride hexahydrate can improve the performance of refractories;
3.As a catalyst for the production of non-ferrous metals, yttrium chloride hexahydrate can improve the extraction rate and purity of non-ferrous metals.
4.As an additive to improve the viscosity of rubber, yttrium chloride hexahydrate can improve the performance of rubber products.
In conclusion, yttrium chloride hexahydrate, as an important inorganic salt, has a wide range of applications in many fields.
