White Quartz Crucible

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 crucible is used to melt solid caustic soda?Why not quartz crucibles?: A metal crucible can not be used with a porcelain crucible, because the reaction of caustic soda and silicate can not be used in ceramics

Q: What happens when carbon carbon crucibles are cracked?: After a long period of use, its silicon vapor corroded the edges of the carbon and carbon parts;

Q: Why are fused quartz transparent and opaque?: Quartz glass is a kind of special glass containing only single silica component. Because of the type of technology, raw materials, quartz glass, glass, often called foreign silicate quartz glass, fused silica, fused quartz, synthetic fused silica, and no clear concept of transparent, translucent, opaque quartz.

Q: A brief introduction to quartz crucibles: HF can not contact, high temperature, easy and effect of carbonate caustic alkali metal.

Q: What are the main differences between the corundum crucible and the quartz crucible?: HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (first drying at 212 degrees) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as cleaning liquid.

Q: External surface macular problem of arc type quartz crucible: In order to solve this problem, you can start from two aspects: the 1 is the melting of sandblasting, cutting and transportation and storage process, do not touch the pollutants; such as dirty gloves, equipment oil, touch, dust, etc.. 2 is pickling. Hydrofluoric acid blister for a few minutes, rinse with deionized water, water resistivity is higher than 12 trillion, 14 or 16 better.

Q: What are the sizes of arc quartz crucibles?: 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. Today, the world's semiconductor industry developed countries have replaced the small transparent quartz crucible with this crucible. It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on.

Q: Can quartz crucibles be used as ROI for fluorine compounds?: Ceramic crucible: heat of 1200 degrees; suitable for K2S2O7 acid melt samples.; generally can not be used with NaOH, Na2O2, Na2CO3 and other alkaline substances as flux melting, in order to avoid corrosion of porcelain crucible. Porcelain crucible and hydrofluoric acid exposure; porcelain crucible can dilute hydrochloric acid washing boiling cleaning.

Q: What are the functional features of quartz crucibles?: Quartz is fragile and easy to break, so we should pay attention to it.
