KINGCERA Zirconia Toughened Alumina (ZTA) introduces ZrO₂, Cr₂O₃ and TiO₂ with similar lattices to Al₂O₃ in the ceramic formula, resulting in higher strength and toughness than alumina ceramics. ZTA ceramic wear liner is a new type of super wear-resistant and impact-resistant liner. This is composite product made of zirconium and aluminum vulcanized to a steel plate with rubber.
