Silicon Carbide - Reaction Bonded Rod - online alogue

To manufacture Reaction Bonded Silicon Carbide (RBSC), Silicon is infiltrated into a pre-formed silicon carbide/carbon powder green body which is then fired. This gives rise to around 10% free silicon, which fills the pores. The resulting microstructure has low porosity and a very fine grain.

Sintered Silicon Carbide ( SiC ) Properties and Appliions

Nov 13, 2000· Low porosity. Good wear resistance in sliding and abrasive environments Heat Exchanger Tubes. Sintered Silicon Carbide tubes are used in shell and tube heat exchangers in the chemical process industry. The tubes used in these appliions are often over 4 m in length. Self sintered silicon carbide carries a slight price premium compared

ERG Aerospace Duocel® Silicon Carbide Foam

Duocel Silicon Carbide can operate effectively up to 2200°C, which makes it suitable for a nuer of high temperature appliions including but not limited to heat exchangers, filters, composite panels, and heat shielding. SiC can endure the extreme conditions that one would expect from solid ceramic materials but at a fraction of the weight.
