Effect of crucible cover material on …

01.03.2011· First, the silica crucible (SiO 2) is dissolved and the oxygen and silicon atoms enter into the melt; second, the dissolved oxygen atoms are transported to the gas/melt interface and evaporate as SiO gas; third, the SiO is carried away by the argon gas flow to all of the graphite components and reacts with them to produce gas-phase CO; fourth, the resultant CO …

Crucibles-Clay-Graphite-Vs-Silicon-Carbide

18.08.2018· Clay graphite crucibles are OK, but they are very susceptible to thermal shock, which means if they are heated too quickly they will crack, silicon carbide crucibles do not suffer from thermal shock. A five to seven year service life from a high quality silicon carbide crucible is not unusual at hobby foundry level, as long as the crucible is properly cared for.

Silicon carbide crucible - Starrbide - Morgan …

Starrbide crucibles are carbon-bonded silicon carbide crucibles, which are characterized by excellent thermal conductivity and high chemical erosion resistance. Due to their carbon content, SiC crucibles have excellent stability at high temperatures and are therefore particularly suitable for processes where the temperature is changing frequently and where high heating rates are …

Matching Your Crucible to Your …

Silicon carbide crucibles provide excellent resistance to elevated temperature erosion and to chemical corrosion. Also, when isostatically pressed, crucibles form a random arrangement of the graphite in their structure. This contributes to creating denser products that can survive erosive and corrosive conditions more effectively.
