MANUFACTURING METHOD OF FUNCTIONAL METAL OXIDE MATERIAL, CERAMIC ELECTRONIC COMPONENT, AND MULTILAYER CERAMIC CAPACITOR
PROBLEM TO BE SOLVED: To provide a manufacturing method of a functional metal oxide material, a ceramic electronic component, and a multilayer ceramic capacitor which have a small variation in a ceramic structure after sintering and a small variation in electric characteristics.SOLUTION: There is provided a manufacturing method of a functional metal oxide material which finally contains at least silicon as an accessory component by 0.2 to 5.0 pts.mol to 100 pts.mol of a main constituent metal element, and the method comprises: a process of crushing and pulverizing a raw material of the functional metal oxide material by cobble stones having silicon nitride as a main component; and a sintering process in which silicon nitride derived from cobble stones is transformed into silicon oxide by oxidation reaction. The metal oxide material has a perovskite type or a spinel type structure. A main component of the functional metal oxide material is barium titanate, quantity of Zr and quantity of Ba contained in the functional metal oxide material due to addition or contamination is severally 0.0 to 0.3 pts.mol for Ti100 pts.mol of barium titanate.
【課題】焼結後のセラミック構造のばらつきが小さく、電気特性のばらつきも小さい機能性金属酸化物材料の製造方法、セラミック電子部品および積層セラミックコンデンサを提供する。【解決手段】最終的に少なくともケイ素を副成分として、主構成金属元素１００モル部に対して０．２〜５．０モル部含有している機能性金属酸化物材料の製造であって、窒化ケイ素を主成分とする玉石で機能性金属酸化物材料の原料を解砕・粉砕する工程と、玉石由来の窒化ケイ素が酸化反応で酸化ケイ素にされる焼成工程と、を備えている。金属酸化物材料は、ペロブスカイト型もしくはスピネル型の構造を有している。機能性金属酸化物材料の主成分はチタン酸バリウムであり、機能性金属酸化物材料に添加もしくはコンタミによって含まれるＺｒ量およびＢａ量は、それぞれ、チタン酸バリウムのＴｉ１００モル部に対して、０．０〜０．３モル部である。【選択図】なし
