Q: How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon: The quartz crucible used for monocrystalline silicon is generally divided into 3 layers: the outermost bubble area, the middle transparent layer (ideally without bubbles), and the innermost layer coating.

Q: Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?: Quartz glass crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque

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: At present, the quartz crucible used in Czochralski silicon is used to make use of barium coating, but how does the oxygen content rise when the coating react with the silicon melt?: Oxygen reduction process can be resolved by other processes, oxygen control within 0.8E17 process, the current strong monocrystalline silicon enterprises, has been very easyIn addition, a message can be disclosed that there are large enterprises in the development of new coatings, because barium coating process is foreign patent, the Chinese people are in Tort

Q: Is the quartz crucible drawn by monocrystalline silicon disposable?: The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable

Q: Why are fused quartz transparent and opaque?: People accustomed to using "quartz" such a simple words to name this material, it is absolutely wrong, because "quartz" is a generic term silica crystalline, and glassy silica in physical and chemical properties are different.

Q: What are the main differences between the corundum crucible and the quartz crucible?: Corundum crucible: corundum crucible is composed of porous fused alumina, hard and refractory; corundum crucible for melting flux samples with anhydrous Na2C03 and some alkaline substances, not suitable for use in Na 202 and NaOH strong alkaline substances and acidic substances as flux (as K2S 207) melt sample.

Q: External surface macular problem of arc type quartz crucible: We often re wash the modified products, never found this problem. There may be cold coating or packaging operations problems

Q: How much fire resistance is quartz crucible?: The quartz glass crucible is usually used for the production of monocrystalline silicon, and the production temperature of single crystal is 1450 degrees

Q: What are the functional features of quartz crucibles?: Functional features of quartz crucibles:1, quartz crucible can be used below 1450 degrees, divided into two kinds of transparent and opaque.2, can not touch the HF and, at high temperature, easy and caustic alkali carbonate reaction and alkali metal.
