Ceramco’s alumina and zirconia material formulations can be divided into two categories: refractory and fully dense. Although both categories are resistant to high temperature and can be used when thermal insulation is an objective for the custom ceramic part, the material performance of each category with regard to thermal shock (cold water on a hot glass) varies significantly.
Thermal Insulation versus Thermal Shock
1.Ceramco’s Refractory Ceramics for Thermal Shock
In general, while this category of materials exhibits higher resistance to thermal shock than category 2 (below), it is a lower strength material than category 2. Material formulations for refractory ceramics include: Ceramco’s A9468 (94% refractory alumina), Ceramco’s A9968 (99% refractory alumina) and Ceramco’s MUL6 (refractory Mullite). Ceramco’s refractory ceramics are excellent in applications such as furnace and/or kiln components, including:
- Kiln and furnace roof anchors and support
- Kiln furniture, setters and standoffs
2. Ceramco’s Fully Dense Ceramics for Thermal Insulation
Fully dense ceramic formulations exhibit much higher strength than category 1 (above). When exposed to thermal shock, however, the density of category 2 materials can result in material fracture. Material formulations for fully dense ceramics include: Ceramco’s A998 (99.8% alumina), Ceramco’s A976 (97.6% alumina), Ceramco’s A96 (96% alumina), and both the yttria and MgO stabilized zirconia formulations from Ceramco.
Thermal Insulation versus Thermal Conductivity
When selecting a ceramic material for its thermal insulation capability, considerations must also be made regarding their thermal conductivity. Ceramco’s fully dense alumina exhibits a thermal conductivity rate almost ten times higher than Ceramco’s zirconia. Ceramco’s fully dense zirconia formulations offer the lowest thermal conductivity of all materials currently offered by Ceramco, making it ideal for Ceramco’s Furnace Board Auger, available from Ceramco.
