Alumina Dish Description

Alumina Dish is developed and made of Aluminum Oxide (Al2O3). Alumina is widely used in structural, electronics, medical and electrical fields as one of the most important ceramic oxides. Due to its high melting point (2054℃) and good chemical stability, Alumina ware is often used during high temperature demanding and contamination-free reactions. Alumina is also a good refractory metal. It can work up to 1750℃ in both oxidizing and reducing atmospheres. It’s also a good electrical insulator used as a substrate for integrated circuits. Considering Alumina’s price, high melting and boiling points, good resistance, strong hardness, and good electrical insulation, Alumina is widely spread and used all over the world in lots of industries.

Alumina Dish Features

  • High melting and boiling points
  • good electrical insulation
  • strong hardness
  • Strong thermal shock resistance
  • good chemical resistance
  • small density and good bio-inertness
