Q: What's the difference between a quartz crucible and a porcelain crucible?: The quartz crucible is white and transparent, and the opal crucible is used below 1200 degrees. The transparent crucible is used below 1400 degrees. The ceramic crucible is used at 1400-1600 degreesThe quartz crucible is resistant to acid and alkali, but hydrofluoric acid is not availableCeramic crucible does not resist strong alkali

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

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?: The coating has the effect of increasing the crystallization rate without increasing the cost and is more impractical

Q: Is the quartz crucible drawn by monocrystalline silicon disposable?: One must, one pot, 3000 pieces! Or made in China?

Q: A brief introduction to 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 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: Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?: Quartz crucibles should be noted for use:(1) HF can not contact, can not be used for heating, carbonate and oxide caustic alkali and alkaline earth metal.(2) the quartz is fragile and easy to break, so we should pay attention to it.(3) except HF, the ordinary dilute inorganic acid of quartz glass crucible can be used as cleaning liquid.4. Heating calcium oxide or calcium hydroxide at high temperature, usually using iron crucible.

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?: It has the advantages of high purity, strong heat resistance, large size, high precision, good heat insulation, energy saving, stable quality and so on; and not HF contact, high temperature, easy and caustic alkali carbonate reaction and alkali metal; quartz crucible suitable for K2S2O7, KHSO4 and Na2S207 as flux melted samples (the first in 212 the degree of drying) as flux sample; quartz brittle, easily broken, use caution; in addition to Hf, the ordinary dilute inorganic acid can be used as a cleaning fluid. 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.
