ZTA Rectangular Crucible Description

Zirconia Toughened Alumina (ZTA) Rectangular Crucible is a composite ceramic with excellent mechanical properties. It is produced by the addition of Zirconia to the main Alumina matrix before sintering. It combines the advantages of both materials, offering superior mechanical strength and abrasion resistance. Zirconia Toughened Alumina (ZTA) is stronger and tougher than ordinary alumina ceramic, and provides high thermal shock resistance, but costs less than zirconia. Additionally, ZTA crucibles exhibit a better surface finish than Alumina making them an excellent choice for bio-compatible and analytical grade applications.
