Are you interested in the suitable applications of different ceramic products? How to make full use of these ceramic products in the applications?
Alumina ceramics
The materials of alumina is relatively simple. The production process of alumina is mature and its basic cost is relatively low. In application, the alumina ceramics is excellent hardness and wear-resist performance. It is mainly used in wear-resistant ceramic pipes and wear-resistant valves as lining materials. It can also weld or paste the lining to the inner wall of industrial vertical mill, powder concentrator, cyclone and other separation equipment with studs on site. Alumina ceramics can provide 10 times the wear resistance of the equipment surface. In terms of wear-resistant perspective, the market share of alumina materials can reach about 60%~70%.
Silicon carbide ceramic products (SiC products)
The most remarkable feature of SiC materials is its good thermal shock resistance. Under high temperature conditions, the material has stable mechanical properties, which can be used stably at 1800 ℃ for a long time.
SiC material can be used to produce the large-sized products with low level deformation in sintering stage. It can be positive to be used as linings in various pipes and other parts of the equipment or projects.
SiC products can be widely used as the preheater hanger in cement industry, the high-temperature wear-resistant ceramic nozzle, coal chute, high-temperature transmission pipeline and other products in cement industry and steel industry. Especially, the burner nozzles in thermal power plant is basically made of SiC materials. Such kind of products have excellent high temperature resistance and wear resistance.
The sintering methods of SiC materials can be divided into reactive sintering method, pressureless sintering method and so on. The SiC products with two sintering methods have similar hardness with Alumina ceramic products. Nevertheless, SiC products are relatively expensive. Among them, the basic cost of SiC products by adopting reactive sintering method is relatively low. However, such kind of products are relatively rough. The basic cost of SiC products by using pressureless sintering method is relatively high. Such kind of products have relatively high density.
Zirconia ceramics
Zirconia ceramic products have superior bending resistant performance. However, zirconia ceramic products are not as brittle as SiC products. The current market price of zirconia powder is relatively high. Zirconia ceramic products mainly used in areas with high impact, or in high and sophisticated fields, such as grinding balls, artificial bones, medical devices, etc.
Through the briefly discussion on the alumina ceramics, SiC materials and Zirconia ceramics, the mainly characteristics and applications have been clear. Hope this can be positive for you to select the suitable materials based on your particular using conditions.
