EagleBurgmann ABC - Reaction-sintered silicon carbide

Reaction-sintered silicon carbide This mixture, compressed into moulded parts, is heated to around 1000 °C, resulting in carbonization of the binders. If necessary, the mouldings are machined prior to immersion in liquid silicon for the final process of siliion at between 1500 and 2200 °C.

Silicon carbide manufacturing process - GAB Neumann

Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).

Ceramic Silicon Carbide SiC Sintered - Silicon Carbide - …

Silicon carbide is an excellent ceramic material for appliions requiring good erosion and abrasive resistance. Silicon carbide ceramics maintains its high mechanical strength in temperatures as high as 1400°C It has higher chemical corrosion resistance than other ceramics.

Products for semiconductor front end processes

SUPERSiC silicon carbide is virtually unaffected by typical semiconductor wet chemistries. Lesser grades of silicon carbide (i.e. sintered) cannot be used in wet chemistries if the protective coating is chipped during normal handling. This chipping will expose the

Silicon Carbide - Reaction Bonded - Ceramic Machining …

Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.
