Laboratory Alumina Ceramic Cupels for Coal Analysis
What's the Aluminum oxide
Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance.
The maximum working temperature is up to 1700 °C with relatively high thermal conductivity.
It is also an electrically insulating material with a high electrical resistivity.
The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
Application:
- Laboratory
- Teaching
- Chemical industry
- Petrochemical industry
- Biochemical pharmaceuticals
