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.

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: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: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: 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?: 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: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: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.

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

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.
