RFQ
1.Why alumina crucible is used?
Alumina Crucible Applications
Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures. Used as a protector for high-temperature thermal couples. Used as a material for the chemical industry due to its high corrosion resistance.
2.What is the maximum temperature for alumina crucible?
The temperature range of alumina crucibles is typically between 1600°C to 1800°C.
3.Can you overheat a crucible?
Never Overheat Your Crucible – Every crucible has a maximum temperature limit.
