Beta SiC as bonding agent for alpha SiC in aggressive environments (all sic material)
Refractories are often made of α-SiC particles which are sintered using various sintering techniques and bonding agents.
Pressing and sintering aids and bonding agents are typically less resistant to aggressive environments than silicon carbide itself.

Example of alpha/beta SiC composite
|
SiCAT has developed an all SiC material, in which α-SiC particles are strongly bonded by a β-SiC matrix.
This material is exceptionally resistant to chemical aggression and can be shaped into bricks,
tiles and more complex shapes using standard presses of the ceramics industry.
These α-SiC/β-SiC composites can be used as protective lining where resistance to corrosion, mechanical strength, and thermal conductivity are required.
