The main components of ceramics

The composition of ceramics is mainly three elements: silicon, aluminum and oxygen.

Traditional ceramics, also known as ordinary ceramics, are products fired from natural silicates such as clay, while modern ceramics are also known as new ceramics, fine ceramics or special ceramics. Commonly used non-silicate chemical raw materials or synthetic raw materials, such as oxides (alumina, zirconia, titanium oxide, etc. ) and non-oxides (silicon nitride, boron carbide, etc. ).

Ceramics have many advantages such as excellent insulation, corrosion resistance, high temperature resistance, high hardness, low density and radiation resistance, and have been widely used in various fields of national economy. Traditional ceramic products include daily-use ceramics, building sanitary ceramics, industrial fine arts ceramics, chemical stoneware, electric porcelain and so on. , various types, different performance.

With the rise of high-tech industry, all kinds of new special ceramics have also developed greatly, and ceramics have become excellent structural and functional materials. They have higher temperature resistance, mechanical properties, special electrical properties and excellent chemical resistance than traditional ceramics.

Selection skills of ceramics:

1, ceramics are fragile, so be careful not to squeeze and collide. If it is a collection, don't touch it with sweaty hands. Wear special gloves and don't pass them around when watching, so as not to fall off. Hold it with both hands when moving.

2. Some used ceramic utensils are soaked in water for about one time after purchase, then washed with detergent, dried with a dry towel and then used. However, if you want to put them away and move them, please use some foam pads so that they won't be fragile.

3. If porcelain is glazed, try to avoid direct sunlight and oil smoke corrosion, and don't touch it often, especially if the rough material is wiped, it will destroy the glaze surface and glaze color.

The underglaze color is relatively simple, as long as hard objects and rough objects are avoided.

4. Whether it is underglaze or underglaze porcelain, it is enough to wipe and maintain it with the soft cotton cloth of the mask dipped in water, and the underglaze color is wiped less frequently.

Porcelain sculpture's maintenance uses a soft brush to clean the dust on the porcelain, and brushes the gaps in the porcelain with a soft brush. But for low-temperature glazed porcelain, it is not easy to wipe it with cloth or brush. Once handled improperly, it is easy to aggravate the peeling of glaze layer.
