Reaction bonded silicon carbide See also Silicon carbide is used to produce epitaxial graphene by graphitization at high temperatures. This is considered as one of the promising methods to synthesize graphene at large scale for practical appliions.  
Infiltration depth – Our reaction-bonding process can fully infiltrate components as thick as 6”, allowing a greater volume of wear material for harsh environments. Reduced weight – Silicon Carbide components will be significantly lighter than the carbide, ceramic, or metal parts they will be replacing, easing installation and reducing downtime.
Reaction bonded silicon carbide (RB SiC) is a durable material that is well-suited for use as a high power laser mirror substrate. The reaction bonded material has a low mass density, a high Young’s Modulus, good thermal conductivity, and a very low coefficient of

Silicon Carbide (SiC) is a ceramic based product available in two forms, namely nitrite bonded Silicon Carbide and reaction bonded Silicon carbine. These products have increased wear resistant properties as opposed to 92% alumina content ceramics and are specifically for areas experiencing extreme high erosion wear.
Reaction-Bonded Silicon Nitride (RBSN) In the early silicon nitride days it was all made via reaction bonding due to the difficulty of producing a silicon nitride powder. With this method, a silicon compact is heated it in a nitrogen rich atmosphere – the nitrogen binds to the silicon powder to produce a porous and not fully dense silicon nitride body.
SSG Precision Optronics, Inc. (SSG) has recently developed a nuer of Reaction Bonded (RB) Silicon Carbide (SiC) optical systems for space-based remote sensing and astronomical observing appliions. RB SiC''s superior material properties make it uniquely
