About Us

Company profile

ZIRAE specializes in the development and production of nanometre ultra-fine high pure zirconium oxide powder,  zirconia beads and  alumina beads for grinding medium, customized zircoina ceramic parts and alumina ceramic parts for industrial using.

In 2014, ZIRAE was founded by advanced material experts in China. It is a key high-tech enterprise integrating R &D, manufacture and sales. The company dedicates in nanometre  ultra-fine high pure zirconium oxide powder (ZrO2 powder), with hydro-thermal technology process, the purity of the core elements can reach 99.99%, and Less hard agglomeration and low defective rate.

So far the invested amount for the factory is 10 million RMB, the total investment is expected to reach 30 million RMB by 2020. At present the annual capacity is 300T,  it is planed to be 1000T by 2020.
ZIRAE holds multiple invention patents with independent intellectual property rights, especially the eight-step purification technology of ZrO2,  and the international advanced separation technology of zirconium and hafnium, providing powerful technical support for the high purity zirconia powder in chemical nanometre scale.
ZIRAE offers customized design in both ceramic material formula and ceramic structure components.  Since its embellishment, ZIREA has been committed to provide nanometre high-tech solutions for many high-tech industries.

Today, ZIRAE focuses on high quality zirconia powder (ZrO2 powder). Our goal, which is continuous innovation, to provide customers with steady high quality, a variety of advanced ceramic materials, has never changed.
