Almath Crucibles offer a variety of alumina products, including Alumina Crucibles, alumina tubes and alumina plates. We are also able to produce alumina furnaceware. Our ALM5848 Alumina Tubes have a maximum operating temperature of 1750°C, making them ideal for high temperature applications.

Our high purity alumina (Al₂O₃ content > 99%) ceramics are purpose built to perform across a wide range of high temperature applications. We use recrystallized alumina in the production of our crucibles as the material offers impressive thermal shock resistance, this is due to the larger grain size (up to 200mm is advantageous).

Our high purity alumina shows considerable resistance to chemical attack due to the lack of glassy phases that tend to determine corrosion resistance.
