WAM® 10 SiC LC – Silicon Carbide Based Low Cement Castable

WAM® 10 SiC LC contains the least amount of Silicon Carbide in this family of products and  is thus the most economical.  The introduction of Silicon Carbide provides additional abrasion resistance in the material matrix. Additionally, Silicon Carbide  provides a degree of alkali resistance making WAM® 10 SiC LC a good choice of product if you are experiencing alkali attack with an alumina based low cement castable system.


Silicon carbide will oxidize to form SiO2 at temperatures above 2500oF in the presence of oxygen. This will initially only occur on the surface to near surface ,but as the product wears the oxidation will continue. Oxidation is not beneficial for abrasion resistance as the SiC is the mineral component which provides this characteristic. However, it is desirable if alkali resistance is the characteristic desired.


WAM® 10 SiC LC finds application in several areas as a general thermal protection material where a degree of abrasion resistance is required. This includes a variety of rotary or feed application areas where a solid material is moving across or impacting the face of the refractory material. Examples are rotary kilns, hearths, troughs, cyclones, fluidized beds.
