Description

上記目的を達成するために、本発明は、セラミックス球体を製造する方法として、セラミックス粉末と造粒剤とを混合してスラリーを調製する工程と、このスラリーを加熱空間に噴霧して造粒剤の含有率が２重量％以下の成形球体を得る工程と、この成形球体にセラミックス粉末と造粒剤とを加えながら転動造粒して成長成形球体を得る工程と、この成長成形球体を造粒剤の含有率が２重量％以下になるまで乾燥する工程と、乾燥後の成長成形球体を焼結する工程とを含むセラミックス球体の製造方法を提供する。セラミックス粉末としては、ジルコニア粉末、アルミナ粉末、窒化ケイ素粉末、炭化ケイ素粉末およびジルコン粉末から選ばれる少なくとも１ 種を含むセラミックス粉末を用いるのが好ましい。また、スラリー中におけるセラミックス粉末の含有率は１０〜９０重量％の範囲内とするのが好ましい。 To achieve the above object, the present invention provides a method for producing a ceramics spheres, preparing a slurry by mixing a ceramic powder and granulating agents, and spraying the slurry into heating space forming A step of obtaining a molded sphere having a granule content of 2% by weight or less, a step of rolling granulation while adding a ceramic powder and a granulating agent to the molded sphere, and a step of obtaining a growth molded sphere; To provide a method for producing ceramic spheres, comprising: a step of drying the spheres until the content of the granulating agent becomes 2% by weight or less; and a step of sintering the grown growth spheres after drying. As the ceramic powder, it is preferable to use a ceramic powder containing at least one selected from zirconia powder, alumina powder, silicon nitride powder, silicon carbide powder and zircon powder. The content of the ceramic powder in the slurry is preferably in the range of 10 to 90% by weight.
