A brief introduction to quartz ceramic crucibles

　　 Ceramic crucible and its technical introduction.

　　With the increasing environmental awareness of people, the introduction of government incentive measures, and the adjustment of the global energy structure, the photovoltaic industry has become one of the representatives of the inevitable trend of new energy replacing traditional energy.

　　 Quartz Solar crucible enterprises are upstream enterprises in the photovoltaic industry chain, relying on the photovoltaic industry for survival and development. Quartz Ceramic crucible (Also known as a solar crucible) is made of high-purity molten Quartz made of Ceramic crucible Generally speaking, its shape is mainly square and cylindrical. Among them, square high-purity Quartz crucibles are used for polycrystalline silicon ingot casting, serving as containers for polycrystalline materials and single crystals ; circular high-purity Quartz crucibles are used for single crystals in single crystal silicon pulling.

　　 Quartz Ceramic crucible is a key component of the polycrystalline silicon ingot furnace for solar cells. This crucible is a container used in the photovoltaic industry to hold molten silicon and make the silicon ingots needed for subsequent processes. It is a consumable container for pulling large-diameter single-crystal silicon and polycrystalline silicon. The operating temperature is above 1500℃, and one crucible can be used up per furnace of silicon products, which is a consumable.

　　Large-size thin-walled square used for melting polycrystalline silicon Quartz Ceramic crucible Extremely strict requirements are placed on the purity, strength, dimensional accuracy, appearance defects, and high-temperature performance of the crucible, as well as strict requirements on quality and thermal shock stability.

　　High-purity molten Quartz Due to its fine structure, low thermal conductivity, small thermal expansion coefficient, high finished product size accuracy, no deformation at high temperature, good thermal shock stability, good electrical properties, and chemical corrosion resistance, it has been widely used in the polycrystalline silicon production of the solar energy industry. Based on the good characteristics of high-purity molten Quartz crucibles, it can be widely promoted and applied in the deep processing of glass, metallurgy, electronics, chemical industry, aerospace and other fields. In this way, Quartz the crucible industry will not be in trouble due to the downturn of the photovoltaic industry.

　　National Standard GB/T 32652—2016《Polycrystalline silicon ingot Quartz Molten material for crucibles Quartz The research and development of materials will promote the production of polycrystalline silicon ingots Quartz Molten material for crucibles Quartz materials, laying a good foundation for manufacturers to participate in international market competition.
