CERAMICS, METHOD FOR PRODUCTION THEREOF AND USE THEREOF
摘要
<p>A ceramics containing titanium diboride and boron nitride as main components, which further comprises 0.2 to 7.5 mass % of strontium oxide, strontium and/or a strontium compound and 0.8 mass % or less (not including 0 %) of a boron oxide, and has a relative density of 90 % or higher; a method for producing the above ceramic; and a vessel for use in the vaporization of a metal which comprises the ceramic. The use of the above vessel reduces the amount of the gas discharged during the heating of a ceramic, and the above vessel for use in the vaporization of a metal (a boat) has a prolonged life since the amount of the gas discharged during theheating is reduced.</p>
