  • Zirconium nitride powder and method for producing same
    Patent number: 11697156
    Abstract: A zirconium nitride powder having a volume resistivity of 107 ?·cm or more in the state of the pressurized powder body hardened at a pressure of 5 MPa, and a particle size distribution D90 of 10 ?m or less when ultrasonically dispersed for 5 minutes in a state of being diluted with water or an alcohol having a carbon number of which is in a range of 2 to 5. Also, the zirconium nitride powder is dispersed in an acrylic monomer or an epoxy monomer to prepare a monomer dispersion. Further, the zirconium nitride powder is dispersed in a dispersing medium as a black pigment and further a resin is mixed to prepare a black composition.

  • ZIRCONIUM NITRIDE POWDER AND METHOD FOR PRODUCING SAME
    Publication number: 20220193767
    Abstract: High ultraviolet transmittance and high blackness can be obtained, and also has high insulating property. A zirconium nitride powder of the present invention has a volume resistivity of 107 ?·cm or more in the state of the pressurized powder body hardened at a pressure of 5 MPa, and a particle size distribution D90 of 10 ?m or less when ultrasonically dispersed for 5 minutes in a state of being diluted with water or an alcohol having a carbon number of which is in a range of 2 to 5. Also, the zirconium nitride powder is dispersed in an acrylic monomer or an epoxy monomer to prepare a monomer dispersion. Further, the zirconium nitride powder is dispersed in a dispersing medium as a black pigment and further a resin is mixed to prepare a black composition.

  • ZIRCONIUM NITRIDE POWDER COATED WITH ALUMINA AND PROCESS FOR PRODUCING THE SAME
    Publication number: 20220119646
    Abstract: A zirconium nitride powder coated with alumina has a volume resistivity is 1×106 ?·cm or higher. Also, an coating amount with alumina is 1.5% by mass to 9% by mass with respect to 100% by mass of the zirconium nitride. Furthermore, an isoelectric point of the zirconium nitride powder coated with alumina is 5.7 or higher.
