Zirconium nitride powder and preparation method thereof
The present invention addresses the problem of providing a high insulating property while achieving a high degree of blackness and high insulating property. The zirconium nitride powder according to the present invention has a bulk resistivity of 107 [Omega] cm or more in the state of a compact compacted with a pressure of 5 MPa, and a particle size distribution D90 of 10 [mu] m or less when ultrasonically dispersed for 5 minutes in the state of being diluted with water or an alcohol having 2-5 carbon atoms. In addition, a monomer dispersion can be prepared by dispersing the zirconium nitride powder in an acrylic monomer or an epoxy monomer. In addition, the zirconium nitride powder can be dispersed as a black pigment in a dispersion medium and mixed with a resin to prepare a black composition.
本发明的课题是在可得到高绝缘性和高黑色度的同时，具有高绝缘性。本发明的氮化锆粉末在用5MPa的压力压实的压坯的状态下的体电阻率为107Ω·cm以上，并且在用水或碳原子数在2~5的范围内的醇稀释的状态下超声波分散5分钟时的粒度分布D90为10μm以下。另外，可将上述氮化锆粉末分散在丙烯酸类单体或环氧单体中来制备单体分散体。此外，可将上述氮化锆粉末作为黑色颜料分散在分散媒质中并且混合树脂来制备黑色组合物。
