Q:Can porcelain crucible, quartz crucible and alumina crucible be filled with aluminium hydroxide?
Quartz glass crucible can be used below 1450 degrees. It is divided into two kinds: transparent and opaque
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.
Q:Can the quartz crucible react with calcium oxide or calcium hydroxide at high temperature?
The main component of the quartz crucible is SiO2. Silica is an atomic crystal with a high boiling point, so it can be used as a crucible material.
Q:How to improve the quality of transparent layer of quartz crucible used for monocrystalline silicon
The quartz crucible used for monocrystalline silicon is generally divided into 3 layers: the outermost bubble area, the middle transparent layer (ideally without bubbles), and the innermost layer coating.
Q:What happens when carbon carbon crucibles are cracked?
The R corner is part of gravity and expansion forces;
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:Is the quartz crucible drawn by monocrystalline silicon disposable?
The used quartz crucibles have been contaminated. Therefore, quartz crucibles used for single crystal drawing are disposable
Q:Why are fused quartz transparent and opaque?
People accustomed to using "quartz" such a simple words to name this material, it is absolutely wrong, because "quartz" is a generic term silica crystalline, and glassy silica in physical and chemical properties are different.
Q:Quartz products are mainly used in photovoltaic and semiconductor industry which links, please expert pointing!
The photovoltaic industry with loaded fixture quartz wafer, the amount is large, our students also have automatic quartz boat loading machine.
Q:The quartz ceramic crucible melting quartz crucible
Quartz ceramic crucible is a key component of the solar polysilicon ingot furnace, it acts as a container for loading of polycrystalline material to high temperature is over 1500 DEG C under more than 50 hours of continuous work, to melt to produce to solar polysilicon ingot.
