Description; Kerasic mortar is alumina bonded silicon carbide. The main problem with silicon carbide is that it oxidises to silica. The alumina bond reacts with the silica to form a mineral called mullite, which has a needle like structure and imparts high strength, and has a melting point of 1850øC. Kerasic mortar is not as electrically conductive as silicon carbide brick.
Kerasic mortar is a fine grained material (maximum particle size 600æm )
Water addition; Use +10 to +16% for putty consistency through plaster to butter consistency.
Packaging; 25kg plastic bags.
Kerasic glue is also available for delicate repair of kerasic castings.
