Alumina Ceramic Crucible

Crucible is an important part of chemical instruments. It is a container for melting and refining metal liquids, as well as solid-liquid heating and reaction. It is the basis for ensuring the smooth progress of chemical reactions.

Description

Product details:

Alumina crucibles are also called corundum crucibles. The shape mainly includes cylindrical, conical, arc, saggar and other shapes. The alumina corundum crucible is made of high-purity alumina (containing more than 99% of AL203), which is resistant to high temperature, corrosion, and erosion. chemical stability and thermal shock resistance. It can be used at 1650 ℃ for a long time, and can also be used at temperatures up to 1750 ℃. It is an ideal container for melting materials, industrial analysis and sample experiments. It is widely used in metallurgy, chemical industry and material science.

 

Product Feature:

The surface of 99 alumina ceramic crucible is smooth and dense, fired in a 1760 degree electric kiln, resistant to strong acid, weak alkali, wear-resistant, and resistant to high temperature of 1700 °. It is widely used in major laboratories, high temperature experiments in colleges and universities, high-end powder calcination, glass, phosphor powder and other industries (please consult if you need detailed technical indicators)


Product Application:

Crucibles are mainly used in metallurgy, powder materials, fluorescent materials, new energy batteries, medical treatment, chemical industry, classroom teaching, laboratories and other places.
