About Us

Company profile

Zirae is a wholly-owned subsidiary of Nanjing Jinli New Material Co., Ltd., located in Nanjing high-tech enterprise in the eastern coastal area of China.

 The company specializes in the production of high-purity hydrothermal and hydrolyzed nano zirconia powder, zirconia dental block, zirconia beads and advanced ceramic parts.

 After 8 years of efforts, the company developed advanced nano zirconia hydrothermal and hydrolysis technology in 2017, and produced high-end zirconia raw material powder with high translucency, high purity, uniform original particle size, high bending strength, strong fracture toughness and high density.

 Zirae established the factory in 2018. The factory is configured and managed according to the cleaning standard of pharmaceutical factory to ensure the environmental cleanliness and strict detection of products, with an accumulated investment of more than 30 million yuan. In 2020, with the increase of demand, the company will continue to expand its production capacity. It is estimated that by the end of 2021, the total investment will reach 150 million yuan, the production capacity of high-end hydrothermal and hydrolyzed zirconia powder will reach 1000 tons, and the production capacity of zirconia dental block and zirconia bead will also expand rapidly.

 We have precise production and testing equipment, strict production process testing and finished product testing and inspection procedures to ensure the stability of product quality.

 Zirae has a high-quality and efficient team. Zirae's technical personnel have a postgraduate degree, and the company has employed industry technical experts from the United States, Germany and Austria as technical consultants. Key management personnel in the top 500 enterprises for many years of employment and management experience, for the rapid development of the company has brought advanced management concepts.

 Our goal is to constantly innovate and provide customers with stable high quality, a variety of advanced ceramic materials, never changed.

Technology advantages

For Zirconia Powder

  • The company applies hydro-thermal technology to zirconia preparation, which can achieve higher purity monodispers and lower sintering temperature required.
  • Impurity content: 0.005%, 1% of ordinary zircoina powder
  • Number of times used in injection moulding: 20~25 times, Increase 33-67%
  • Monodisperse of Powder: Less hard agglomeration, up to first level
  • Sintering temperature: 1250 degrees, 16.1%(energy saving 8.5%)
  • Flexural strength: 1490 MPa, increased by24.17%.

  • More optimized hydro-thermal process technology
  • Uniform particle size of nano-powders optimized  the sintering properties
  • Reducing chloride ion content: minimize the effect of chloride ion on ceramics
  • Minimize the Hard reunion to Improve size uniformity of powder
