The purity of a quartz crucible is actually determined by its raw materials, so in order to improve the purity of the product and enhance its performance, we need to focus on its raw materials. Below, we will understand the requirements for the use of quartz crucible raw materials.
The raw materials for quartz crucibles require high purity, good consistency, and uniform particle size distribution. When harmful components are high, they can affect the melting process of the crucible, affect its temperature resistance, and cause phenomena such as bubbles, color spots, and peeling, seriously affecting the quality of the quartz crucible.

Most impurities in quartz are associated with the formation of quartz, and quartz impurity minerals are the enrichment points of impurities, mainly from two sources. The first is the impurity minerals encapsulated in quartz crystals during quartz growth, mainly silicate minerals and metal oxide minerals. This type of package is divided into two types: solid and gas-liquid. Solid inclusions mainly include mica, epidote, potassium feldspar, hematite, etc; Gas liquid inclusions are mainly composed of crystalline water and gas, with the main components being CO2, H2O, H2O2, N2, CH4, CO, etc. There are fewer gas-liquid inclusions in crystals, and more in quartz, with a higher concentration of over 800mg/Kg. Another type is impurities from secondary pollution during the production process. The air, water, equipment, and operators in the production process can all cause pollution to the product, so we need to have strict requirements and control over its production process.
By understanding the requirements of quartz crucibles for raw materials, we can select according to the requirements and improve the purity of the product.
