Are silicates edible?

Silicates are raw materials for the manufacture of glass, quartz glass, water glass, optical fibers, important parts of the electronics industry, optical instruments, handicrafts and refractory materials, and are important materials for scientific research.

Natural silicon dioxide is called silica and is mainly used in acidic refractory bricks for the metallurgical industry. Pure silica can be used for quartz glass or refining monocrystalline silicon. The appearance of crystallized silica is generally creamy white, grayish white, light yellow and reddish brown. It has a distinctive luster, smooth and continuous section with sharp edges, and great hardness and strength.

Vein quartz is a dense block, pure white, semi-transparent, hair grease luster, the section is shell-shaped, quartz crystallization particles more than 2mm, discernible to the naked eye. Chemical industry for the preparation of silicon compounds and silicates, can also be used as sulfuric acid tower filler. It is also used as filler of sulfuric acid tower. It is used in glass, ceramics and silicate cement in building material industry. It can be used as raw material for smelting ferroalloys such as industrial silicon. Widely used in the chemical industry, is one of the indispensable raw materials in China's chemical industry, but if human pragmatic silicates, will lead to extremely serious sequelae, and even directly on the book of life, of course, in our food also contains a certain amount of silicates, but generally are food-grade, so in order to our life and health and safety, do not easily go to try to use silicates. Try to pass away, of course, do not have to worry too much about written in the ingredient list of some of the silicates can be used, these are through the national testing to meet the standards of food-grade silicates.
