Zirconia Toughened Alumina Powder

Zirconia toughened alumina powder is a white ceramic powder composed of uniformly dispersed alumina and zirconia phases. It features a low sintering temperature, excellent formability, and smooth surface finish after firing. The resulting ceramic components exhibit reduced density, high strength, improved toughness, and excellent wear, corrosion, and thermal resistance. This powder is widely used as a raw material for producing ceramic cutting tool bases, mold parts, wear-resistant liners, valve seats, pump components, and structural parts in textile and mechanical systems. Heeger Materials provides high-quality zirconia toughened alumina powder for advanced ceramic applications.
