Silicon carbide has four major application areas, namely: functional ceramics , advanced refractories , abrasives and metallurgical materials. Silicon carbide has been able to present a large supply of coarse material , can not be considered high-tech products , while high -tech nano- silicon carbide powder is impossible to form a short application of economies of scale .
Silicon carbide ceramics with silicon carbide powder, the reaction sintering powder metallurgy sintering or hot pressing is made . Features high-temperature silicon carbide ceramic biggest strength, good thermal stability , wear resistance, creep resistance. Suitable for casting metals throat mouth , thermowell , gas turbine blades, bearings and other parts. And because of its high thermal conductivity , high temperature conditions also apply to the heat exchanger material can be used for the production of the pump seals .
Obvious characteristics of silicon carbide industry , according to the global understanding of silicon carbide net exports in recent years, the overall growth of silicon carbide products , silicon carbide in various industries have the figure , not only casting , oil, chemical and other major industries, high application , but before small proportion of rubber , industrial applications of new energy growth is also very obvious. A huge market and the center of gravity will further enable the development of silicon carbide industry has been the majority . Enhance our overall competitiveness of the graphite industry, the need to strengthen the protection of domestic resources from the source , starting with the domestic market , starting from the basics, to take the initiative themselves , in order to avoid the kinds of situation long-term sustainability .
Silicon carbide powder production line process:
( A ) take the silicon carbide raw material, the crusher , and sieved to the silicon carbide particles is not more than 5mm , and then shaping machine to be shaped...
