Q:Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?
Silica is acidic oxide, with acidic oxides and alkaline oxides, transparency, alkali reaction,The reaction principle is: SiO2+CaO=CaSiO3SiO2+Ca (OH) 2=CaSiO3+H2OTherefore, the crucible will corrode and the medicine in the crucible will spoil.
Q:What crucible is used to melt solid caustic soda?Why not quartz crucibles?
Iron. React with ceramic or glass silica ash
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 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: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?
The coating has the effect of increasing the crystallization rate without increasing the cost and is more impractical
Q:What are the functional features of quartz crucibles?
The quartz crucible is suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.
Q:What happens when carbon carbon crucibles are cracked?
If the whole crucible is used, the external force of the crucible will cause the fiber damage of the carbon crucible when the quartz crucible is taken.In addition, the carbon carbon crucible may cause cracks during the fabrication of the preform.
Q:How much fire resistance is quartz crucible?
It depends on the raw material used in your crucible. It is usually above more than 1100 degrees, but it must be guaranteed to not be crystallized
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:What are the sizes of arc quartz crucibles?
HF can not contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal. 3. quartz crucibles are suitable for melting samples with K2S2O7, KHSO4 as flux, and using Na2S207 (first drying at 212 degrees) to treat samples with flux.
We can supply a wide range of patterns and colors that are similar to natural granite or marble. Equipped with some of the most advanced production equipment in this industry, we output 400,000 square meters of crystallized glass panel a year. Producing environmentally friendly building materials, our products have obtained ISO9001 certification. In addition to our existing product range, we also welcome customized orders for completion.
