- High Purity Alumina (99.9%) - featuring
dimensional strength, temperature, chemical and wear
resistance
- Alumina-Mullite - excellent thermal
shock resistance due to low thermal thermal expansion and good
mechanical strength
- Alumina-Titania - excellent thermal
shock resistance for applications where silica content is not
acceptable
- Alumina-Zirconia - high fracture
toughness, excellent wear and erosion resistance
