Engineering ceramic materials, hard materials for mechanical seals:

Engineering ceramics is a large class of ceramic materials used in engineering. It is characterized by excellent chemical stability (good corrosion resistance, good temperature resistance), high hardness, abrasion resistance, but high brittleness and impact resistance Low toughness. Table 5-7 lists the typical manufacturing methods of some foreign ceramic materials. Currently commonly used engineering ceramics are alumina ceramics (Al2O3), silicon carbide ceramics (SiC) and silicon nitride ceramics (Si3N4), of which silicon carbide Ceramics and silicon nitride ceramics are called new types of ceramics.
