Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon: The higher the quality of the transparent layer, which is the bubble less, more uniform thickness, R thickness of the thicker crystal: 1. in straightening isolated bubble layer bubbles into the soluble silicon in 2, the province will have a layer of transparent bubble burst into tiny particles of silica. The bubble burst into soluble silicon is the most direct impact on the single drum off, the second is the increase of oxygen content

Q: What's the difference between a quartz crucible and a porcelain crucible?: The quartz crucible and the ceramic crucible have different temperature resistance, and the acid and alkali are different

Q: What crucible is used to melt solid caustic soda?Why not quartz crucibles?: Iron. React with ceramic or glass silica ash

Q: Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!: Quartz in these two sectors: 1, mainly used in the preparation of high purity quartz crucible, when polysilicon ingots and crystal growth will be used in high purity quartz crucible, which is the main purpose of the quartz crucible in the photovoltaic industry, a large amount of cut. 2. High-purity quartz rings are needed in the polysilicon reduction furnace.

Q: A brief introduction to quartz crucibles: Quartz crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is the basic material for drawing large diameter monocrystalline silicon and developing large-scale integrated circuits. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. He has high purity and strong heat resistance, large size high precision, good heat insulation, energy saving, stable quality etc..

Q: The quartz ceramic crucible melting quartz crucible: Because of the use of extremely harsh conditions, the crucible of purity, strength, appearance defects, internal quality, high temperature performance, thermal shock stability and dimensional accuracy has very strict requirements.

Q: Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?: The main component of the quartz crucible is SiO2. Silica is an atomic crystal with a high boiling point, so it can be used as a crucible material.

Q: How much fire resistance is quartz crucible?: The long-term use of the crucible temperature is 1100 degrees, but pulling when the stone is outside, so can be used for a long time. The crucible will deform about 1300 degrees. 1100 degrees without deformation.

Q: Can quartz crucibles be used as ROI for fluorine compounds?: Quartz crucible can be used below 1650 degrees. It is divided into two kinds: transparent and opaque. The translucent quartz crucible fabricated by arc method is a basic material for developing large scale integrated circuits.

Q: What are the functional features of quartz crucibles?: In addition to HF, quartz glass crucibles are usually diluted with inorganic acids, which can be used as cleaning solutions.

We are a high-tech enterprise specialized in the production of semiconductor monocrystal silicon and solar grade high purity quartz crucibles. One of the greatest advantages of us is that we enjoy more than 100 solar grade monocrystalline furnaces in China,which can help to test the stability of our quartz crucibles. The sales volume of our solar grade quartz crucibles has always been in the top 3 among other manufacturers since 2007.
