Abstract

PURPOSE:To obtain a releasing sheet used to calcine ceramic products and preventing the melt bonding of ceramic substrates to each other and carburization from a graphite shelf board by forming a BN film on the surface of a base material. CONSTITUTION:The surface of a combustible base material having a low ash content such as paper of plastic of 20-80mum thickness is coated with a mixture of 40-95wt.% BN powder of <=100mum particle size and >=80wt.% purity with 60-5wt.% org. binder such as PVA and/or silicone resin such as liq. silicon rubber by a means such as a calender roll system, a doctor blade system or spray coating to obtain a releasing sheet.
