摘要

PROBLEM TO BE SOLVED: To provide a hexagonal boron nitride sintered body which can be sintered at a low temperature; and to provide a method for manufacturing the same.SOLUTION: A hexagonal boron nitride powder containing oxygen not only on the surface of the powder but also insde thereof is pressure formed to make a preformed body (preformation step), and the preformed body is sintered in a non-oxidizing gas or in vaccum at ≥600°C and 1,100°C (sintering step).
