Characteristics of carbonaceous products
Carbonaceous products have low thermal expansion coefficient, high thermal conductivity, good thermal shock resistance and high temperature strength. It is not softened at high temperature for a long time. It is not eroded by any acid and alkali. It has good salt resistance. It is also not wetted by metal and slag. It is light quality. It is a high quality high temperature resistant material. The disadvantage is that it is easy to oxidize at high temperature and is not suitable for use in oxidizing atmosphere.
