It provides support for but does not replace the need for metal melters and crucible suppliers to work closely together in the crucible selection process. The modern crucible is a highly heterogeneous, graphite-based composite material, which relies on its material composition and control of the graphite’s structural alignment to achieve the performance required.
Mechanisms of graphite crucible degradation in contact …
1/1/2020· The formation mechanisms of silicon carbide (SiC) from Si melt, and aluminum carbide from a Si-20 wt%Al melt in graphite crucibles are compared. It is shown that graphite crucible can be passivated by controlled formation of a dense SiC layer on the surface, and further can be used for different melts treatments with no melt infiltration and crucible destruction.
Silicon-carbide can be found in block-knife sharpeners, but I found they were too expensive. Instead, I used a silicone-carbide rubbing stone for under $14 found at the hardware store. The crucible I used was metal with a higher melting point that the melting I was attempting to smelt.

Acheson''s technique for producing silicon carbide and graphite is named the Acheson process. In 1896, Acheson received a patent for his method of synthesizing graphite,  and in 1897 started commercial production.  The Acheson Graphite Co. was
Silicon metal production - Carbon and Graphite
This process is known as "vapor phase epitaxy" and uses silicon carbide coated graphite susceptors to hold the silicon wafers. Controlled doping of "P" or "N" type impurities is also possible in silicon epitaxial technology.
This silicon carbide graphite crucible fixed the Oxidation problem that traditional graphite can not solved. Based on our Oxidation tests, usually the traditional graphite crucible can be used at 1800 degree Celsius for about 90 days while siliconized graphite crucible can be used at 1200 degree Celsius for many years without Oxidation.
