MANUFACTURING METHOD OF ALUMINA PARTICLES
To provide a manufacturing method that can produce alumina particles having a predetermined particle size range of about several tens μm to about several hundreds μm of particle size (average particle diameter D50) by using a more simple method with good yield without using a conventional granulation method.SOLUTION: A manufacturing method of alumina particles produces alumina particles having an average particle diameter D50 of 80 to 200 μm by granulating raw material alumina powder with an average particle diameter D50 of 0.2 to 1 μm using an ultrasonic vibration sieve provided with a mesh with sieve mesh of 250 to 400 μm.SELECTED DRAWING: None
【課題】従来の造粒法を用いることなく、粒子径（平均粒子径Ｄ５０）が数十μｍ〜数百μｍといった所定の範囲の粒子径を有するアルミナ粒子を、より簡便な方法で、収率良く製造できる製造方法を提供する。【解決手段】平均粒子径Ｄ５０が０．２〜１μｍの原料アルミナ粉末を、篩目が２５０〜４００μｍのメッシュを備えた超音波振動篩いを用いて造粒処理して、平均粒子径Ｄ５０が８０〜２００μｍのアルミナ粒子を製造することを特徴とするアルミナ粒子の製造方法である。【選択図】なし
