Quartz crucibles have the advantages of high purity, strong temperature resistance, large size and high precision, good insulation, energy saving, and stable quality, and their applications are becoming increasingly widespread. Polycrystalline silicon wafers are widely used in solar cells, and their quality directly affects the conversion efficiency of solar cells. Due to the characteristic of high temperature and no chemical reaction with silicon, crucibles are used as containers in the polycrystalline silicon ingot process, which also puts forward requirements for the production of quartz crucibles:

Solar cells, as a clean energy source, have received widespread attention worldwide. Among them, polycrystalline silicon has relatively low requirements for raw materials, making it a material with a high industrialization rate. Quartz crucible is a kind of fused silica ceramics, which is widely used in the technology of polysilicon ingots in the solar photovoltaic industry.
In the process of polycrystalline silicon ingot casting, the quartz crucible is subjected to a very harsh operating environment, which requires it to withstand a high temperature of 1550 degrees Celsius and work continuously for more than 50 hours at a time. Therefore, the purity and various performance requirements of the raw materials used for the crucible are high, and the production technology of the crucible is also difficult. Currently, the development trend of quartz crucibles is large-sized and thin-walled.
Quartz crucible is the container and key consumable material for polycrystalline silicon ingots, therefore higher requirements have been put forward for its production. Its detection work is a very important link, and the detection of crucibles is developing towards on-site detection.
