The role of quartz crucible in polycrystalline silicon ingots
      
            
      The usage characteristics of quartz crucible have gained popularity among many users.It has the advantages of high purity,strong temperature resistance,large size and high precision,good insulation,energy saving,and stable quality,which are also the main reasons for its increasingly widespread use.Polycrystalline silicon wafers are widely used in solar cells,and their quality directly affects the conversion efficiency of solar cells.Quartz crucibles serve as containers in the polycrystalline silicon casting process due to their high temperature and non chemical reaction with silicon,which also puts forward requirements for the production of crucibles
Solar cells,as a clean energy source,have received widespread attention worldwide.Polycrystalline silicon has relatively low requirements for raw materials,making it a material with a high industrialization rate.Fused silica crucible is a kind of fused silica ceramic,which is widely used in the technology of polysilicon ingot in solar photovoltaic industry.
In the process of polysilicon ingot casting,the use environment of fused silica crucible is very harsh.It must withstand the high temperature of 1550℃and work continuously for more than 50 hours at one time.Therefore,the purity of raw materials used in the crucible and the requirements for various properties are high.Therefore,the production technology of the crucible is difficult.It is important to know that the current development trend of the crucible is large size and thin wall.
Quartz crucible is the container and key consumable material for polycrystalline silicon ingots,therefore higher requirements have been put forward for its production.If you encounter any problems during the use of quartz crucible,you can consult us.
