♦ High alumina purity:al2o3>99%,good corrosion resistance.
♦ High temperature resistance,long working time at1600℃, short working time at 1800C.
♦ Good thermal shock,no easy to crack.
Based on above features,99 al2o3 alumina melting ceramic crucible with wall thickness from 1.3mm to 5mm is widely used for analysis ,melting , firing and processing of material applied in laboratory and various industries,such as metallurgy, chemical industry , materials science and so on.
