Ceramics is the composition of SiO2 or silicates

Ceramics is a silicate, crystal is silicon dioxide

Silicon dioxide is an atomic crystal, hard and wear-resistant, judging from this point of the composition of the brick must not be silicon dioxide.

Red brick is clay, shale, gangue and other raw materials, after crushing, mixing and kneading to artificial or mechanical pressing molding, after drying at a temperature of about 900 degrees Celsius in the oxidizing flame burned into the sintered building bricks. So the chemical composition of the brick is mainly clay, and clay contains silicates.

Ceramics, English: china. The Chinese invented pottery as early as about 8000-2000 B.C. (Neolithic period). Vessels fired with clay are called pottery, and those fired with porcelain clay are called porcelain. Ceramics, on the other hand, is a general term for earthenware, stoneware and porcelain. The ancients called ceramics ou. All wares made from clay of two different natures, terra cotta and china clay, as raw materials, through the process of batching, molding, drying, roasting and other processes can be called ceramics.

Ceramics raw materials mainly from rocks, which are largely composed of silicon and aluminum. Ceramics are also made from such rocks, which are artificially heated to make them strong, much like the creation of igneous rocks. So chemically, the composition of ceramics is not very different from that of rocks.
