Some knowledge points about crucibles, told to you by a porcelain crucible manufacturer

　　 Porcelain crucible manufacturers Consider Crucibles, as an important component of chemical equipment, are containers for melting and refining metal liquids and heating solid-liquid reactions, and are the basis for the smooth progress of chemical reactions. Early crucibles were made of clay, and one of the early uses of platinum was to make crucibles. With the development of preparation technology, crucibles can now be made of any material capable of melting or altering its contents.

　　 Porcelain crucible manufacturers Consider There are many types, models, and specifications of crucibles, which can be selected arbitrarily, with strong applicability, and can guarantee the purity of the melt. Ceramic crucibles are an important part of crucibles. Ceramic crucibles can be divided into Quartz crucibles, corundum crucibles, boron nitride crucibles, zirconia crucibles, etc. According to their properties, they are used in different occasions.

　　 Quartz Ceramic crucibles are made of high-purity molten Quartz Ceramic crucibles made have fine structure, low thermal conductivity, small thermal expansion coefficient, good thermal shock resistance, good electrical properties, and good chemical resistance. They are widely used in the glass deep processing industry, metallurgy industry, electronics industry, chemical industry, aerospace and other fields. Generally speaking, Quartz The shapes of ceramic crucibles are mainly square and cylindrical.

　　 Porcelain crucible manufacturers Consider quartz Solar crucible enterprises are upstream enterprises in the photovoltaic industry chain and the foundation for the survival and development of the photovoltaic industry. Quartz Ceramic crucible (also called solar crucible) is a ceramic crucible made of high-purity molten Quartz Ceramic crucibles are made. Generally speaking, its shape is mainly square and cylindrical. Among them, square high-purity Quartz crucibles are used in the polycrystalline silicon casting process as containers for polycrystalline silicon melt and crystal growth; circular high-purity Quartz crucibles are used in the single crystal pulling process.

　　 Porcelain crucible manufacturers Consider quartz Ceramic crucibles are key components of polycrystalline silicon casting furnaces for solar cells. This crucible is a container used in the photovoltaic industry to hold molten silicon and produce the silicon ingots required for subsequent processes. It is a consumable vessel for pulling large-diameter single-crystal silicon and polycrystalline silicon. The operating temperature is above 1500, and one crucible can be used for each silicon product production. It is a consumable.

　　 Porcelain crucible manufacturers Consider From a usage perspective, thin-walled, large-size square Quartz ceramic crucibles have extremely strict requirements for their purity, strength, dimensional accuracy, appearance defects, high-temperature performance, as well as quality and thermal shock stability.

　　 Porcelain crucible manufacturers Consider 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 good chemical corrosion resistance, it is widely used in the production of polycrystalline silicon in the solar energy industry. Based on the good characteristics of high-purity electrofused Quartz crucibles, they can be widely promoted in the glass deep processing industry, metallurgy industry, electronics industry, chemical industry, aerospace and other fields. In this way, Quartz The crucible industry will not be in trouble due to the downturn in the photovoltaic industry.
