Beta Silicon Carbide - Superior Graphite

Both also are resistant to high temperatures, although alpha has greater temperature resistance. Alpha silicon carbide is made at temperatures exceeding 2,400°C, whereas beta silicon carbide is normally made in the 1,500 to 1,600°C range. At about 2100°C, beta will convert into alpha. The different crystalline structure of alpha silicon carbide does give it some different properties than beta, however.

Product Profile: Enhanced Silicon Carbide Refractories

In refractory appliions, the oxidation of silicon carbide leads to volume and linear expansion, which, if severe enough, can result in cracking and failure of the refractory products. As is the case with many materials exposed to air, silicon carbide forms a very thin passivation layer of silica on grain surfaces, even at room temperature.
