Zirconia Granulated Powder
Basic Information:
Zirconium oxide granulation powder VK-RYK series products are produced in the form of spray-dried particles. The standard diameter of one particle is about 50um. Each large particle is composed of many small particles, and its primary particle size is about 50nm. . The yttrium-stabilized zirconia powder produced by our company through the chemical method ensures the balanced dispersion of yttrium oxide, and strict quality control ensures the stable quality of each batch of products. After the yttrium stabilized zirconia airflow powder is granulated, the powder flows smoothly and is easy to use. Ceramics made of zirconia granulated powder are called tough ceramics because of their stress-induced phase transformation and toughness. They have high strength, good mechanical properties, and smooth surfaces. They are now widely used in various fields. Recognized by many downstream enterprises.
The 3mo1 yttria-stabilized tetragonal zirconia granulated powder VK-RYK1 is currently the most widely used biomedical material. 8mol yttrium stabilized zirconia granulated powder VK-RYK3 is a high-purity cubic zirconia sintered body with extremely high ionic conductivity, especially suitable for oxygen sensors and solid oxide fuel cells.
