FORMED HEXAGONAL BORON NITRIDE BODY, HEAT-TREATED HEXAGONAL BORON NITRIDE BODY AND PROCESSES FOR PRODUCING THE SAME
The invention relates to a material composition and a formed body comprising hexagonal boron nitride, a water-soluble boron compound and a further inorganic compound, wherein the further inorganic compound is able to split off a gaseous phase at a heat treatment at a temperature of at most 1000 °C, and wherein the further inorganic compound is able to form with the water-soluble boron compound(s) a water-insoluble boron compound at a heat treatment at a temperature of 200 - 1000 °C. The invention further relates to a heat-treated formed body obtained by heat-treating the formed body according to the invention at a temperature of 200 - 1000 °C, wherein the heat-treated formed body comprises hexagonal boron nitride and the reaction product between the water-soluble boron compound and the further inorganic compound as described above. The invention further relates to processes for making the formed body and the heat-treated formed body.
