Novel aluminum nitride microsphere powder preparation method
The present invention discloses aluminum nitride microsphere powder, which has a diameter of 20 nm-10 [mu]m. According to the preparation method, a metal inorganic salt is adopted as a precursor and a sol-gel method and a gas nitriding reducing method are combined to prepare the aluminum nitride microsphere powder at the low heat treatment temperature. According to the present invention, the method has characteristics of simple preparation process, simple operation, short preparation process period, low heat treatment temperature, substantial energy consumption reducing, low raw material cost and low equipment cost, and is suitable for industrial mass production; and the prepared ALN microspheres have characteristics of regular shape, adjustable particle size, uniform size distribution, good crystallinity, high purity and the like, can be used for producing circuit packaging materials, ultraviolet photoelectric detectors, pressure sensors, thermal radiation sensors, field effect transistors, light emitting diodes, transparent ceramics, nitride phosphor and the like, and is further the material with the excellent performances such as high temperature resistance, corrosion resistance and anti-oxidation property.
