Al₂O₃
Pure alumina
Hard, high-temperature resistant and electrically stable — the most widely used technical ceramic.
Typical use
Crucibles, furnace tubes, substrates, insulators, wear parts
Materials
Materials
Eight ceramic material systems covering heat resistance, insulation, wear resistance and cost. One part can often be made in more than one of them.
ZrO₂
Zirconia
Tougher than most ceramics, with high wear resistance and chemical stability.
Typical use
Thread guides, wear liners, structural parts
MgO
Magnesia
Good resistance to basic media and molten metals.
Typical use
Crucibles, high-temperature linings, thermocouple protection tubes
MgO·SiO₂
Steatite
Cost-effective and electrically insulating, and easy to form into small precision parts.
Typical use
Insulating beads, bushings, textile ceramics, terminals
3Al₂O₃·2SiO₂
Mullite
Outstanding thermal-shock resistance for repeated heating and cooling cycles.
Typical use
Kiln furniture, furnace tubes, setters, high-temperature supports
Mg₂Al₄Si₅O₁₈
Cordierite
Low thermal expansion, excellent thermal-shock resistance and low weight.
Typical use
Kiln plates, saggers, setters, honeycomb carriers
SiC
Silicon carbide
High strength at temperature, good thermal conductivity, wear and corrosion resistant.
Typical use
Kiln furniture, nozzles, wear plates, heat-exchange parts
Composite
Two or more ceramic systems combined where strength, insulation and cost must be balanced.
Typical use
Custom structural parts, machinable ceramic, special-duty parts
