Description

Technical Field

[0002] Crucible is a cup-shaped vessel used in the laboratory to heat solids at high temperatures. It is generally used to burn solid substances or evaporate, concentrate or crystallize solutions. It can also ensure the purity of the smelted material. Quartz crucible is an important tool for single crystal silicon pulling. It also has an important influence on the crystal pulling rate, the number of crystal pulling times and the quality of the crystal rod. During the single crystal silicon melting process, the quartz sand in the quartz crucible will vaporize, and when the temperature drops, it will solidify into white solid particles attached to the inner surface of the crucible, resulting in an increase in the roughness of the inner surface of the crucible. Therefore, the inner surface of the quartz crucible needs to be polished after a period of use.
