<p>A sintered, hexagonal boron nitride body (2a, 2b) is produced through at least one pressing process and subsequent sintering process by using powder (P) made of a hexagonal boron nitride, whose density is deliberately set to a value less than 1.6 g/cm^3. Studies have shown that the boron nitride body (2a, 2b) exhibits high isotropy due to the selection of lower density in comparison with conventional hexagonal boron nitride bodies, especially, which relates to thermal conductivity and an coefficient of thermal expansion, which are also largely temperature-independent.</p> |
