BORON NITRIDE CERAMIC SHEET SINTERED COMPACT AND PRODUCTION METHOD THEREOF
To provide a ceramic sheet sintered compact made of boron nitride having sufficient lightness with little discoloration after firing and enduring severe handling such as dropping, and to provide a method for producing the same.SOLUTION: A production method of the present invention includes (1) a molding step of preparing a molded body including a plurality of first linear coated bodies and a plurality of second linear coated bodies from a raw material paste containing a raw material powder of boron nitride, a sintering aid and a medium, and (2) a firing step of firing the molded body using a firing jig in which the exposed surface of the firing atmosphere contains boron nitride to obtain a sintered ceramic sheet made of boron nitride containing a first linear portion layer composed of a plurality of first linear portions and a second linear portion layer composed of a plurality of second linear portions. The ceramic sheet sintered compact made of boron nitride includes a plurality of first linear portions and a plurality of second linear portions, and has a surface lightness L* value of 80 or more.SELECTED DRAWING: Figure 1
【課題】焼成後に変色が少なく十分な明度を有すると共に、落下等の厳しいハンドリングに耐えうる窒化ホウ素製セラミックスシート焼結体およびその製造方法を提供する。【解決手段】本発明の製造方法は、（１）窒化ホウ素の原料粉、焼結助剤および媒体を含む原料ペーストから複数条の第１線条塗工体および複数条の第２線条塗工体を含む成形体を作成する成形工程、ならびに（２）焼成雰囲気の曝露面が窒化ホウ素を含んでなる焼成治具を用いて成形体を焼成し、複数条の第１線条部で構成される第１線条部層および複数条の第２線条部で構成される第２線条部層を含む窒化ホウ素製セラミックスシート焼結体を得る焼成工程を含む。本発明の窒化ホウ素製セラミックスシート焼結体は、複数条の第１線条部および複数条の第２線条部を含み、表面の明度Ｌ＊の値が８０以上である。【選択図】図１
