Nanjing Zirae Advanced Materials Co., Ltd is a leading high-tech enterprise which produce high pure, ultra fine and nanometer ZrO2 powder by hydro-thermal technology.
We produce 41%/43%/45%49% translucency white blocks as well as multi-layer color blocks.
Zirae was founded by Nanjing science and technology leader, who has a number of 31 national invention patents with independent intellectual property rights, especially the eight-step purification technology and zirconium - hafnium separation technology is a leading level in the world. It provides solid technical support for the production of chemical nanometer high purity zirconium oxide. The preparation technology of fine microcrystalline high purity zirconia products guarantees the good performance, stability and differentiation of zirconia products.
We have our own D&R center as well as production base that makes us supply our customer advanced quality production with competitive price.




Zirae have registered related patents and use the latest hydrolysis processes and nano-technologies to produce zironium oxide powder. Through complete control over materials and production processes, ZIRAE can maintain consistent high purity and quality.
