Advanced ceramic materials are produced using highly refined and purified powders that, in many cases, are synthetically produced using high temperatures or chemical reactions. When formed and sintered properly these powders result in product that are very strong, very high in abrasion resistance, can withstand high use temperatures, very good chemical resistance, and very stable.
Advanced ceramics such as alumina, aluminum nitride, zirconia, silicon carbide, silicon nitride and titania-based materials, each with their own specific characteristics, offer a high-performance, economic alternative to conventional materials such as glass, metals and plastics.
Why Ceramic?
Technical ceramic materials have the ability to make products lighter, more efficient, longer lasting, reduce maintenance intervals, and reduce operating costs.
They are frequently being used to replace metals, polymers, and refractory materials in a wide variety of applications due to their notable high temperature capability, hardness, and electrical properties.
