Product Summary of Alumina

Alumina, also known as aluminium oxide is an electrically insulating material with relatively high thermal conductivity for a ceramic. It could be argued as being one of the most cost effective of all ceramic materials and as a result is one of the most widely used. Its combination of high thermal conductivity and low thermal expansion imparts good thermal shock resistance.

Characteristics of Alumina include:

• Electrically insulating
• High thermal conductivity
• High strength and stiffness
• Available in a range of purities
• Excellent resistance to strong acids and alkalis at elevated temperatures
