This paper describes interfacial reaction in pressureless-sintering of hexagonal boron nitride (h-BN) with feldspar at low temperature. In order to improve performance of sintered h-BN with feldspar composite, low purity h-BN and melted feldspar have been utilized for composite. Low purity h-BN contains at least 30 % oxide. Melted feldspar has been used for sintering aid to produce sintered composites at a temperature below the melting point of feldspar. Experimental results show that the bulk density of low purity h-BN with melted feldspar composite was satisfactory results. The relative density of h-BN with melted feldspar composites in air achieved 95.6 % at 1573K sintering, and 96.1 % at 1473K sintering.
