ZTA Micro Powder Description

ZTA (Zirconia Toughened Alumina) is an advanced technical ceramic composed of 10-20% volume of ZrO2 in alumina. The inclusion of pure ZrO2 into alumina creates a composite material known as ZrO2 toughened alumina ceramics. When the ZrO2 content is appropriately added, the toughness of the ceramic is significantly enhanced. ZTA ceramics are recognized for their superior strength and toughness compared to standard alumina ceramics. Due to the high cost of pure zirconia, ZTA with its excellent toughness provides a cost-effective alternative.

ZTA Micro Powder FAQs

Q1: Why is ZTA powder preferred for high-strength and high-toughness applications?
A: Adding zirconia particles to alumina significantly enhances its toughness and fracture resistance without compromising hardness and wear resistance. This makes ZTA ideal for applications requiring high mechanical reliability.

Q2: What particle sizes are available for ZTA powder?
A: ZTA powder is available in various particle sizes, typically ranging from 1 μm to 100 μm for zirconia particles, tailored to meet specific application needs.

Q3: How does the particle size of zirconia affect the performance of ZTA?
A: Smaller zirconia particle sizes allow for better dispersion and more effective toughening of the alumina matrix, leading to improved mechanical properties such as increased toughness and strength. The optimal particle size depends on the specific application requirements.
