The operating temperature of quartz crucible

The use of quartz crucibles is still quite widespread, mainly because of its good performance, high purity, strong temperature resistance, and good insulation properties. It should be noted that the detection of quartz crucibles is still an important step. One of the most important aspects of detection is temperature measurement. Next, let's take a look at the specific usage question: how much does it need to be used?
Quartz crucibles can be used in two types: transparent and opaque below 1450 degrees. The semi transparent quartz crucible using arc method is an essential basic material for drawing large-diameter single crystal silicon and developing large-scale integrated circuits. Today, developed countries in the international semiconductor industry have replaced small transparent quartz crucibles with this crucible. He has the advantages of strong temperature resistance, large size and high precision, good insulation, energy saving, and stable quality.

At present, the coating technology for crucible production has been widely used by most manufacturers, which is to apply a layer of barium dioxide solution on the surface of a crucible made of ordinary quartz sand to form a fine layer. The fine layer can prevent the reaction between silicon and quartz crucible during the high-temperature drawing process of single crystal silicon and improve the crystallization rate.
The quartz crucible mentioned above can be used below 1450 degrees, but cannot be used above 1450 degrees. Its application is becoming more and more widespread and has great development prospects in the future. Before using it, you can learn more about quartz crucibles to better use it.
