What kinds of silicate materials do inorganic nonmetallic materials include?

Types of silicate materials in inorganic nonmetallic materials Silicate materials in inorganic nonmetallic materials are used to manufacture various products and materials such as ceramics, glass, enamel, cement, refractory materials, bricks and tiles. And belongs to the inorganic nonmetallic material industry. Inorganic nonmetallic materials, mainly silicate materials, are often juxtaposed with metal materials and polymer materials as three important modern materials. Silicate materials mainly include the following:

1, Glass: There are many kinds of glass, besides the ordinary glass mentioned above, there are also: timely glass, optical glass, tempered glass, glass fiber and so on. Main raw materials: soda ash: Na2CO3；; Limestone: CaCO3；; Time: silica

Main reaction:

Na2CO3+SiO2===Na2SiO3+CO2

CaCO3+SiO2===CaSiO3+CO2

2. Cement: Cement is an important modern building material. The main raw materials are clay, limestone and gypsum. Main ingredients:

Tricalcium silicate: 3caosio2; Dicalcium silicate: 2cao SiO 2 tricalcium aluminate: 3CaO Al2O3.

3. Ceramics: various products made of natural clay and various natural minerals through crushing, mixing, molding and calcination. In the past, people called things made of clay and fired at high temperature in special kilns ceramics, which is the general name of pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products with inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or clay-containing mixture through mixing, molding and calcination. From the roughest earthenware to the finest exquisite ceramics, it belongs to its scope. Its main raw materials are silicate minerals (such as clay, timely, etc.). ) is taken from nature, so it belongs to the category of "silicate industry" together with glass, cement, enamel, refractory and other industries.
