MATERIALS
Choosing the proper ceramic material can be difficult. Here are some typical material uses to point you in the right direction. Please click on each of the materials for a material property chart.
ALUMINA The most common material used for structural ceramic parts is alumina. It is used in applications from aerospace to medical, to bearings to analytical instrumentation. High purity alumina ceramics lends itself well to corrosive environments.
ZIRCONIA is often used in wear applications requiring improved fracture toughness and stiffness over alumina. Its high material cost usually warrants its usage only where alumina fails.
ZIRCONIA TOUGHENED ALUMINA, (ZTA) is often used in wear applications as an intermediate solution between alumina and zirconia. It offers an increased fracture toughness over alumina with a material cost less than that of zirconia.
STEATITE Many heater and electrical insulators are made out this material because of its relatively high temperature and electrical resistance, and relatively low cost.
MULLITE offers many of the same properties as alumina, with a slightly better thermal shock properties.
CORDIERITE Its good thermal shock properties lend this material to be used in refractory applications. Its low thermal expansion and thermal conductivity make it a good choice for fixtures and other applications.
GRADE "A" LAVA also has good thermal shock properties which allow it to be used in welding applications. Low thermal conductivity is also a highlight of this material.
Superior Technical Ceramics also manufactures parts made from macor® and boron nitride
