Rongsheng is a company mainly engaged in refractory materials. Yttrium-stabilized zirconia is also one of its popular products. We are a yttrium-stabilized zirconia manufacturer with advantages in price, export volume, quality, customized services, إلخ. لذلك, the export volume of yttrium-stabilized zirconia reached a new high in 2024.

What is yttrium-stabilized zirconia powder?

Pure zirconium oxide is in the monoclinic phase at room temperature. When the temperature rises to about 1173°C, it will transform into the tetragonal phase. When it rises to 2370°C, it will transform into the cubic phase, and it will become a liquid phase at 2690°C.

Pure zirconium oxide is cooled from high temperature to room temperature. When it passes the phase transition temperature, the tetragonal phase transforms into the monoclinic phase. Due to the drastic change in volume, the sintered finished product contains microcracks and is often unusable. Zirconium dioxide does not exist in the cubic phase (fluorite crystal structure) at room temperature, but by adding other oxides, the temperature range in which zirconium dioxide can exist stably in the cubic phase can be greatly increased. Zirconium dioxide doped with phase stabilizers is called stabilized zirconia.

Application range of yttrium-stabilized zirconia powder

Yttrium-stabilized zirconia can be used in high-strength, high-toughness wear-resistant products: mill linings, أدوات القطع, wire drawing dies, hot extrusion dies, nozzles, valves, balls, pump parts, various sliding parts, إلخ.
Functional ceramics, structural ceramics: electronic ceramics, bioceramics
Piezoelectric components. Oxygen-sensitive resistors. Large-capacity capacitors;
Artificial gemstones: abrasive materials
Yttrium-stabilized zirconia can also be used as refractory materials: electronic ceramic burning support pads, refractory materials for melting glass, and metallurgical metals; its applications in high-tech fields are increasingly expanding.
Silane-modified nano-ZrO2 particles can significantly improve the flexural strength of nano-ZrO2/PMMA composite materials when the addition amount is 3.0%.
