In senior one chemistry, cement, ceramics and glass are three main silicate products. What materials are they made of?

In the production process of cement, limestone and clay are used as main raw materials, which are crushed, mixed and ground into raw materials, which are sent to a cement kiln to be calcined into mature materials, and then a proper amount of gypsum (sometimes mixture or additive) is added for grinding.

Ceramic ceramics are materials and various products made of clay as the main raw material and various natural minerals through crushing, mixing, molding and calcination. 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.

Glass-glass: A relatively transparent solid substance, which forms a continuous network structure when melting, and its viscosity gradually increases and hardens during cooling, and it will not crystallize. The common chemical oxide of glass (Na2O CaO 6SiO2) is mainly composed of silicon dioxide, which belongs to a mixture.
