Silicon Carbide Raw Materials

This heat exchanger features a higher strength, higher purity and stronger corrosion resistance in comparison with graphite heat exchangers. Compared with enamel heat exchangers, heat exchangers made using a pressure free sintered silicon carbide has a stronger acid resistant performance, which avoids chipping that occurs when using enamel materials.

Tantalum heat exchangers bring enduring benefits

silicon carbide and graphite heat exchangers. Alfa Laval tantalum heat exchangers use plate technology, resulting in a very compact size. The optimized geometry, highly turbulent flow, good conductivity of the material and high mechani-cal stability all add up to

Silicon Carbide Coatings: Improving Graphite Product

Silicon carbide is applied onto graphite as thin films using the process of chemical vapour deposition (CVD). This deposition method allows for precise control of layer thickness, which enables the production of well-defined SiC-coated products with the desired properties for particular applications.

They may be made of clay, graphite, silicon carbide, porcelain, water cooled corper or a relatively infusible metal. Metals such as nickel and zirconium are also used as melting crucibles. Graphite crucible can withstand the high temperature of metals and has a

Silicon Carbide and Graphite heat exchangers

GAB Neumann designs and manufactures impregnated graphite and silicon carbide process equipment for ultra-corrosive applications in the chemical and pharmaceutical industries. Both materials have exceptional corrosion resistance and excellent thermal

Crucibles

2018/8/18Clay graphite crucibles are OK, but they are very susceptible to thermal shock, which means if they are heated too quickly they will crack, silicon carbide crucibles do not suffer from thermal shock. A five to seven year service life from a high quality silicon carbide crucible is not unusual at hobby foundry level, as long as the crucible is properly cared for.
