FORMED HEXAGONAL BORON NITRIDE BODY, HEXAGONAL BORON NITRIDE GRANULATES FOR MAKING THE SAME, AND PROCESS FOR PRODUCING THE SAME
The invention relates to a formed body comprising hexagonal boron nitride wherein the formed body has a Brinell hardness of at least 2 HBW 2,5/2, and wherein the formed body is obtainable by a process at temperatures of at most 100 °C, and wherein the Brinell hardness is measured according to DIN EN ISO 6506-1 (2013). The invention further relates to a process for making said formed body, wherein the process comprises the steps (a) providing a powder comprising hexagonal boron nitride powder; (b) mechanically pre-treating the powder of step (a) to obtain a pre-treated powder; (c) optionally granulating the pre-treated powder of step (b) in order to obtain a granulated powder; and (d) forming the pre-treated powder of step (b) or the granulated powder of step (c) into a shape in order to obtain a formed body; and wherein all process steps for making the formed body are carried out at temperatures of at most 100 °C.
