Potassium cryolite, English Name: potassiumcryolite, properties: white or light gray powder, slightly soluble in water. Relative density 2.9-3.0, melting point 1000 purpose: used as brazing agent for aluminum, aluminum alloy and stainless steel, degassing agent and flux in the manufacturing process of aluminum alloy, and also used as active filler for glass, ceramics and friction agent.

Potassium cryolite has special composition and chemical structure. It is neutral and its pH is about 7. It can effectively play its role in grinding and abrasive, improve the grinding speed of grinding wheel and the working speed of grinding wheel. The price of potassium cryolite is higher than that of traditional cryolite, which is its defect. Shandong potassium cryolite, however, is a by-product of aluminum titanium boron grain refiner production enterprises. Potassium cryolite not only has the same quality as potassium cryolite production, but also has strong price advantage and market competitiveness. The application of potassium cryolite in grinding wheel profession in China is still in its infancy. Potassium cryolite has huge potential market not only in China, but also in the development of our country.

The difference between as like as two peas is different from that of the white potassium. The gray potassium and cryolite are the same as those of the white potassium ice material. The raw material of the gray potassium cryolite is gray, and the raw material of the white potassium cryolite is white. However, the price of grey is cheaper than that of white. As the production of white needs to be controlled, a little grey raw materials cannot be used, so the cost is relatively increased.

Gray potassium cryolite is mainly used as aluminum alloy additive and flux because of its low price. Because it does not affect the use, it is relatively white and cheap. White is generally used for grinding wheel, brazing agent and other relatively high-end occupations. This is the difference between potassium cryolite gray and white.
