Different manufacturers produce custom grades for a specific range of applications.

Why are they preferred over MoSi2 heating elements? Generally, the Silicon Carbide heating elements survive high temperatures furnaces and kilns. Since those furnaces and kilns are too wide or long, the SiC heating elements do it effectively, unlike MoSi2.

As compared to metallic elements, the Silicon carbide heating elements are more versatile, especially when they are capable to bear higher operating temperatures and higher watt loadings. They can be easily changed even when the furnace or kiln is extremely hot.

The pre-oxidative silicon dioxide layer deteriorates under a hard vacuum, which is why the lowest maximum element temperature is achieved under a normal vacuum. There is a set of precedents to achieving high-quality results from these heating elements. Factors like volatility in higher temperatures and oxidized regions jeopardize the performance of a heating element.

As manufacturers put it straight, the SiC heating elements cannot survive under all atmospheres. Different atmospheres affect and shorten the lives of SiC heaters. Therefore, specialized manufacturers utilize coating SiC heating elements that prevent rapid aging and performance.

It was found that some harmless volatiles turned harmful after mixing with certain volatiles in a furnace. Similarly, there is an existence of several harmless volatiles in a furnace or kiln. To perform, different coatings are applied to SiC heating elements, which would help it survive the impact of varying atmospheres. Only responsible and specialist manufacturers can provide these services.
