Technical Field

[0002] Silicon carbide crucible is a commonly used container in laboratories for heating, melting, burning or distilling liquid or solid substances. However, there are some problems with the traditional silicon carbide crucible during use. First, since the heating method of the silicon carbide crucible is usually through an external heating source, the heat distribution inside the silicon carbide crucible is uneven, which makes the material prone to local overheating or underheating during the heating process, thus affecting the heating effect of the material. Secondly, the traditional silicon carbide crucible is prone to heat loss during the heating process, reducing the efficiency of heat utilization. In addition, the traditional silicon carbide crucible usually needs to be manually scraped when cleaning, which is cumbersome and ineffective. At the same time, it is sometimes easy for the material to stick to the wall during the material heating process.

[0003] Therefore, it is necessary to improve the traditional silicon carbide crucible to improve its heating uniformity and cleaning effect.
