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: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: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: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:A brief introduction to quartz crucibles
In addition to HF, ordinary dilute inorganic acids can be used as cleaning solutions. Quartz crucibles used for drawing monocrystalline silicon in China are 18 inches and 20 inches 22 inches. There are also 22 or more crucibles used by manufacturers. At present, the crucible technology produced by large crucible manufacturers in China is quite mature. Its production and use of raw materials, quartz sand imported by the United States and Norway high purity quartz sand two. There are also small factories using homemade materials. The quartz crucibles produced by their raw materials have certain influence on the stability of the drawn monocrystalline silicon.The current production of crucible coating technique has been used by most manufacturers is in ordinary quartz sand solution for crucible surface coated with a layer of two barium oxide solution so as to form a dense layer, the dense layer can prevent the silicon and silicon high temperature quartz crucible drawing process to improve reaction rate.
Q:External surface macular problem of arc type quartz crucible
After cleaning the pot can not see the macula, and heated to about three, Baidu appeared macular, because the reason is simple: no cleaning.
Q:What's the difference between a quartz crucible and a porcelain crucible?
The quartz crucible and the ceramic crucible have different temperature resistance, and the acid and alkali are different
Q:How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon
In order to improve the quality of the transparent quartz crucible layer three: 1: use of raw materials, it is the monopoly of the uni quartz sand.2. vacuum arc furnace production method of vacuum and high pure health, it is important to you in one process pay attention to detail is no good.3., the production process and temperature, etc., these are the details of the process, such as temperature, cooling time ah...
Q:What crucible is used to melt solid caustic soda?Why not quartz crucibles?
Do not use ceramic crucibles or quartz crucibles. Use metal crucibles, preferably with silver cruciblesThe quartz crucible reacts to form the sodium silicate (2NaOH+SiO2=Na2SiO3+H2O) ceramic crucible
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.
