What factors affect the crystallization process of sodium metasilicate

Nowadays, the chemical industry has been constantly moving forward, and many new chemical raw materials have gradually emerged. The development of sodium metasilicate as one of the important chemical raw materials has also attracted much attention. The following sodium metasilicate manufacturers are Let us introduce the factors that affect the crystallization process.
During the crystallization process of sodium metasilicate, in order to control the crystal quality and obtain a product with uniform particle size, seeds of appropriate particle size and quantity are added to the crystallization solution, and gentle stirring is used throughout the process to make the seeds more evenly suspended. In the entire solution, the number of secondary nucleations is reduced so that the crystallized material only grows upward on the surface of the seed crystal.
The amount of seed crystal added depends on the amount of material that can be crystallized during the entire crystallization process, the particle size of the seed crystal, and the particle size of the desired product. Assuming that no primary nucleation seed crystal is generated during the process, the number of finished grains is equal to the number of newly added seed crystal particles in the formula, seed, finished product mass, seed, average particle size of finished product, and physical property constants of sodium metasilicate.
Regarding the crystallization process of sodium metasilicate from an aqueous solution, according to the crystallization phase transformation analysis, due to the narrow width of its metastable zone, it is easy to enter the unstable zone, and generally increased seed crystals are used. If the finished product is required to have an average particle size, taking into account the inevitable nucleation quantity of the solution itself, the actual amount of species added is ~ the theoretical amount.
With the rapid development of ceramics and other related industries, the market demand for sodium metasilicate is also growing rapidly. Only by understanding the reasons that affect its crystallization can it have greater room for development.
