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:Is the quartz crucible drawn by monocrystalline silicon disposable?

One must, one pot, 3000 pieces! Or made in China?

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:What happens when carbon carbon crucibles are cracked?

The R corner is part of gravity and expansion forces;

Q:What are the functional features of quartz crucibles?

Quartz is fragile and easy to break, so we should pay attention to it.

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: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: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:Can quartz crucibles be used as ROI for fluorine compounds?

Ceramic crucible: heat of 1200 degrees; suitable for K2S2O7 acid melt samples.; generally can not be used with NaOH, Na2O2, Na2CO3 and other alkaline substances as flux melting, in order to avoid corrosion of porcelain crucible. Porcelain crucible and hydrofluoric acid exposure; porcelain crucible can dilute hydrochloric acid washing boiling cleaning.
