What is potassium silicate? Potassium silicate is also known as potassium metasilicate. It is divided into three kinds: ①K2SiO3=154.29, colorless crystal, often turquoise block or glassy solid—melting point of 976℃. Dissolved in water, hot water, or under pressure is easier to dissolve. An aqueous solution is alkaline and insoluble in ethanol. The acid decomposes the sialic acid gel. Absorb water in air.②K2Si2O5=214.37, a colorless orthorhombic crystal. Relative density is 2.456 (25 / 4℃), the melting point of 1015 ± 10℃.③K2Si4O9 · H2O=352.56, white orthorhombic crystal. Relative density 2.417 and resolved when heating to 400℃. Dissoluble in water and insoluble in ethanol. The appearance is colorless or slightly yellow and translucent to transparent glass substance. Have moisture absorption. There is a strong alkaline reaction. In the acid decomposition to precipitate the silica. Slow soluble in cold water or almost insoluble in water (depending on its composition) and insoluble in ethanol. Potassium silicate is usually used to manufacture electrodes, electrodes for welding, reducing dyes, fire retardants, and as a fluorescent screen coating layer and soap fillers. At the steady state, the hyaline liquid is viscous and bluish-green. Easy soluble in water and acid, and precipitate colloidal silicic acid, the higher the potassium content, the more soluble. Insoluble in alcohol.
Main uses of potassium silicate Potassium silicate can make advanced electrodes, glass, ceramic and refractory materials, cleaning agents, etc. The application examples are as follows: Preparation of a potassium silicate glass, Follow the following steps: Step 1: Mix ethyl orthosilicate, water, and ethanol in a container into a homogeneous solution. Then, hydrochloric acid and KCl solution were added under stirring conditions. Get the mixture; Step 2: Put the mixture into the oven for constant temperature treatment for 28~30h; Step 3: After forming the gel, Reduce the oven temperature, And subject it to constant temperature treatment for 50 to 60 h; get potassium silicate semi-finished glass; Step 4: Remove potassium silicate glass from the oven and placed in the crucible, The crucible in an oven at a temperature of 200 to 300℃, Then, the oven temperature was increased to 500 to 600℃, After 2 – 3 h of constant-temperature treatment, Close the oven, After potassium silicate glass is cooled to room temperature, To get a potassium silicate glass, Its high purity, and uniformity, And the preparation method is simple, Low requirements for production equipment. Price of potassium silicate The different price of potassium silicate purity is also different. The market price of potassium silicate is in the process of dynamic change.
