Ceramics refers to the combination of pottery and porcelain. Ceramics are a mixture of many complex components, and the components of ceramics are different according to the origin of ceramics. However, the main components of most ceramics are silica and silicates, including aluminum silicate and calcium silicate. Silicon dioxide and silicate have relatively stable chemical properties and are not easy to react with acid and alkali.
Moreover, there is often a layer of enamel on the surface of ceramic objects, which is a special crystal form of alumina and has corrosion resistance. Therefore, the corrosion resistance of ceramics is also excellent, but the acid and alkali resistance of various ceramics is also different.
Ceramics have excellent properties and wide applications;
Ceramics have the characteristics of hardness, wear resistance, electrical insulation, acid and alkali corrosion resistance, fire resistance, liquid and gas impermeability and good chemical stability, so ceramics are widely used in life. In the field of architecture, ceramics are widely used in floor tiles, wall tiles, drainage pipes, sanitary ware and so on.
In the chemical field, ceramics are used to make refractory materials for various containers, pipes, valves, liquid pumps, crucibles, evaporating dishes, burning boats, mortar, reaction kettle and various high-temperature industrial furnaces; In power, ceramics are used to make insulators, motor bushings, insulation pillars, low-voltage electrical appliances and lighting appliances on high and low-voltage transmission lines.
