What is potassium silicate? Potassium silicate is a colorless or yellowish translucent to transparent glassy substance with hygroscopicity and a strong alkaline reaction. It decomposes in acid to precipitate silicon dioxide. It is slowly soluble in cold water or almost insoluble in water (depending on its composition) and insoluble in ethanol. Potassium silicate is used to manufacture welding electrodes, reducing dyes, and fire retardant. It is also used as a fluorescent screen coating layer and soap filler. In a stable state, it is a transparent viscous liquid; It is blue-green. It is soluble in water and acid and precipitates colloidal silicic acid. The higher the potassium content, the more soluble it is. It is insoluble in alcohol. If it is slightly harmful to water, do not let undiluted or a large amount of products contact groundwater, watercourses, or sewage systems. Without government permission, do not discharge materials into the surrounding environment. If it is used and stored according to specifications, it will not decompose, there is no known dangerous reaction, and it avoids oxides and acids. It is soluble in water and acid and free colloidal silicic acid; the higher the potassium content, the more soluble it is. It is insoluble in alcohol.
Use of potassium silicate Protective coating (to prevent "frost," i.e., salt surface crystallization). Catalyst adhesive, used as a detergent in the manufacture of glass and ceramics, the phosphor is glued on the picture tube and coated on the outside of the welding rod, which can overcome splash. It is used as a reducing dye, fire retardant, welding electrode adhesive, and inorganic coating adhesive, and also used in the production of soap, medicine, refractory materials, etc. It is used to manufacture welding electrodes, reducing dye, and fire retardant. In addition, It can be used as a fluorescent screen phosphor binder and soap filler. It is used to manufacture welding electrodes, welding electrodes, reducing dyes, and waterproof agents. It can also be used as a fluorescent screen phosphor binder and soap filler. It can be used as an accelerator in concrete admixtures.
Synthesis of potassium silicate 1. Melting method: mix silica sand and caustic potash in a certain proportion and then add them into the melting furnace. Heat them to 1200~1400 ℃ with heavy oil or electricity. When a fully molten transparent body is formed, cool and solidify it from the furnace, then put it into an autoclave. Dissolve it with pressurized steam (0.2MPa). Leave the solution still to clear, remove impurities, and concentrate the clarified solution to obtain potassium silicate products 2. Adopt the melting method (i.e., dry method). After the silica sand and caustic potassium are acted in the melting furnace, they are dissolved by pressurized steam.
Price of potassium silicate Potassium silicate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of potassium silicate. A large amount of large amount will be lower. The price of potassium silicate can be found on our company's official website.
