Magnesium Trisilicate is a composition of hydrous magnesium silicate. The content of MgO should not be less than 20.0%, and the content of SiO2 should not be less than 45.0%; the ratio of SiO2 to MgO should be 2.1 to 2.3. White orthorhombic crystal, melting point 1910 ° C, relative density 3.21 This product is insoluble in water or ethanol. It decomposes in concentrated alkali to form Mg(OH)2, which is decomposed in hot hydrochloric acid to form silicic acid and magnesium chloride, which can be decomposed by hydrofluoric acid. The presence of forsterite minerals exists in nature. Due to the openness of the crystal structure of the product, it contains holes and pores which are connected to each other and connected to the outside. It has a well-developed pore structure and a large specific surface area, so that it has good adsorption performance and molecular sieve function, and can provide specificity. 

Magnesium trisilicate is used in medicine to make antacids, can neutralize stomach acid and protect ulcer surface, and has a slow and long-lasting effect. It is used to relieve stomach pain, heartburn (heartburn) and acid reflux caused by excessive gastric acid. Used in the food industry as an anti-caking agent, filter aid, and filming agent. In addition, it can also be used as a deodorant, a decolorizing agent, etc., as well as in the ceramic and rubber industry.
