Corrosion Resistance High Quality Refractory Alumina Laboratory Ceramic Crucible Tray


We make 99.7%Al2O3 crucibles and boats, which max working temperature is 1800ºC and 95% Al2O3 crucibles and boats, which max working temperature is 1500ºC.

Crucible capacity from 0.5ml to 10000ml. very big sized can be made as your design.

We have cylindrical type crucibles, conical type crucibles, boat and other special shaped crucibles or boats according to your design.

Our Advantages


1.High purity, 99.5% alumina purity makes sure high working temperature.
2.Large quantity mould in stock, you will find a suitable one.
3.Very small and very big sized ones can be made.
4.Inspection: each single crucible and boat will be checked before shipping.
5.Low transportation cost. We have long time cooperated shipping agency, which can provide very low prices.
