Abstract: To provide zinc oxide particles having a surface coated with organosilicon, the particles exhibiting a high dispersibility and excellent water repellency. Zinc oxide particles having a surface coated with organosilicon, the zinc oxide particles having a primary particle size of 0.1 µm or less as measured based on a transmission electron micrograph, and a median size based on a volume of 0.15 µm or less, where the median size is determined by charging the powder in isopropyl alcohol, dispersing the powder by application of ultrasonic wave with a rated output of 600 W and an oscillation amplitude of 100% generated by an ultrasonic homogenizer at a normal temperature for 30 seconds, and measuring the dispersion by a laser diffraction scattering method.

Abstract: Provided are a method of manufacturing a silicon-containing oxide-coated aluminum nitride particle, the method being capable of manufacturing a silicon-containing oxide-coated aluminum nitride particle having improved moisture resistance in which a high thermal conductivity inherent to an aluminum nitride particle is maintained; a method of manufacturing a heat dispersing resin composition containing the silicon-containing oxide-coated aluminum nitride particle; and the silicon-containing oxide-coated aluminum nitride particle. A method of manufacturing a silicon-containing oxide-coated aluminum nitride particle including an aluminum nitride particle and a silicon-containing oxide coating covering the surface of the aluminum nitride particle, the method comprising: a first step of covering the surface of the aluminum nitride particle with an organic silicone compound including a specific structure; and a second step of heating the aluminum nitride particle covered with the organic silicone compound at a temperature of 300°C or more and less than 1000°C, wherein the content of carbon atoms in the silicon-containing oxide-coated aluminum nitride particle is less than 1000 ppm by mass.
