CERAMIC POWDER AND MANUFACTURING METHOD THEREOF
To provide a ceramic powder excellent in uniform mixing properties of coarse ceramic powder and fine ceramic powder.SOLUTION: A ceramic powder 10 is used in a multilayer ceramic capacitor 20. The ceramic powder 10 includes a coarse ceramic powder 11, and a fine ceramic powder 12 having a smaller particle size than the coarse ceramic powder 11, and the grain size of the coarse ceramic powder 11 is five times larger than the grain size of the fine ceramic powder 12, and the weight ratio of the fine ceramic powder 12 to the total of the coarse ceramic powder 11 and the fine ceramic powder 12 is 20 wt.% or more and 50 wt.% or less. The fine ceramic powder 12 is supported on the surface of all of the coarse ceramic powders 11.SELECTED DRAWING: Figure 1
【課題】粗大セラミック粉末および微細セラミック粉末の均一混合性に優れたセラミック粉末を提供する。【解決手段】セラミック粉末１０は、積層セラミックコンデンサ２０に用いられる。セラミック粉末１０は、粗大セラミック粉末１１と、粗大セラミック粉末１１よりも粒径の小さい微細セラミック粉末１２と、を含む。粗大セラミック粉末１１の粒径は、微細セラミック粉末１２の粒径の５倍より大きく、粗大セラミック粉末１１および微細セラミック粉末１２の合計に対する微細セラミック粉末１２の重量比率は、２０重量％以上５０重量％以下である。すべての粗大セラミック粉末１１の表面に微細セラミック粉末１２が担持されている。【選択図】図１
