ZTA toughened ceramic powder granulation powder 25%
1. The ZTA powder with a dispersed coupling agent system features a nanoscale tetragonal zirconia phase as the continuous phase, while ultrafine alpha-alumina grains are uniformly distributed throughout the continuous phase, providing dispersion strengthening effects. By strictly controlling the powder production process, we obtain powders with stable and reliable quality, uniform particle distribution, and a wide sintering window. The sintered bodies exhibit high strength, high toughness, uniform grain size, and high density, making them suitable for applications with stringent structural requirements.
Ceramic components are now replacing zirconia ceramics in many fields.
2. Applications: Suitable for manufacturing various structural ceramics, electronic ceramics, bioceramics, advanced refractory materials, optical communication devices, and human...
Industries and products including gemstone manufacturing, oxide sensors, solid oxide fuel cells, and grinding and polishing.
3. Packaging: 20 kg/bag in plastic woven bags, 25 kg/bag in plastic woven bags, 20 kg/drum in drums.
Note: 1. The specific surface area and median particle size can be controlled according to customer requirements. 2. Air-flow powder and granulated powder can be produced based on user needs. 3. % refers to the mass percentage.
