alumina crucible advantage

There are four kinds of crucibles, corundum crucibles, alumina crucibles, ceramic crucibles and iron crucibles. The four kinds of crucibles have different uses. Today, I want to share with you about the use of zirconia crucibles.


Arc alumina crucible, square alumina crucible, alumina corundum ark (rectangular alumina ceramic crucible), straight (cylindrical) alumina crucible and various special-shaped alumina ceramic crucibles. Suitable for various laboratories, laboratories, metal and non-metal sample analysis and melt and various industrial analysis.


 alumina crucible characteristics:


1. High purity: Al2O3 > 99%, good chemical corrosion resistance


2. Good temperature resistance, long-term use at 1600 and short-term use at 1800.


3. Good resistance to quench and heat, not easy to burst.


4. Grouting high density and high purity alumina crucible.

Alumina special refractories include high-grade refractories, ceramics, lightweight heat insulation products, fibre products and amorphous products. Its main applications include: transparent alumina ceramics can be used as high-temperature observation window glass for high-pressure sodium lamp tube microwave cover.


In the electronic industry, we make circuit substrates, electronic sockets, high-voltage ceramic shell radome spark plugs, etc. Abrasives and abrasives such as high temperature wear-resistant bearings and various props, etc. The sealing rings of plunger pump components used in chemical industry, etc. Metallurgical non-ferrous industry metal melt pipeline.


Corundum crucible lining material for ultra-high temperature kiln. Crucibles for smelting and purifying rare and precious metals of high purity metal superalloys. High temperature and corrosion resistant lining materials for petrochemical industry. High temperature insulation of thermocouple tube of high temperature furnace tube, etc. High temperature resistant kiln gasket pressing rod and pressing block, etc.
