A quartz crucible is actually a container made by shaping high-purity quartz sand through a mold and producing it at high temperatures using the arc method. It has the characteristics of high temperature resistance, long service life, and high purity, and is mainly used as an auxiliary consumable for semiconductor and solar drawn monocrystalline silicon rods.
The use of quartz crucible:
Quartz crucibles are generally used when heating solutions or when evaporating volatile substances in solutions through heating.
The main chemical component of a quartz crucible is silicon dioxide, which does not react with other acids except hydrofluoric acid and is prone to react with caustic soda and alkali metal carbonates.
Quartz crucibles have good thermal stability and can be directly heated on a flame.
Quartz crucibles, like glassware, are prone to breakage, so special care should be taken when using them. Quartz crucibles can be used below 1450 ℃ and are divided into transparent and opaque types. Early quartz crucibles were completely transparent, and this transparent structure easily led to uneven heat transfer conditions, increasing the difficulty of crystal rod growth, so this type of crucible was phased out for use.
Quartz crucibles are mainly used in fields such as semiconductors and photovoltaics. Due to the high precision of products and rapid technological development, the photovoltaic industry has increasingly strict requirements for the purity and accuracy of quartz crucibles. The quartz products industry in our country started relatively late, and only a few large-scale enterprises have reached advanced levels in quartz crucible technology. In terms of technological change, with the continuous iteration of downstream industry technology, quartz crucible manufacturing enterprises need to keep up with the times, develop and produce products that meet the needs of downstream fields in a timely manner, and meet the requirements of downstream customers to reduce costs and increase efficiency in order to maintain a competitive advantage.
Quartz crucibles have a wide range of applications and unlimited future development.
