Abstract
A sealing member is produced from form-pressed boron nitride powder, while adding an inorganic or organic binding agent. Such boron nitride powder is obtained during the machining of boron nitride blocks composed of hexagonal boron nitride. This powder can be fractionated according to particle size and the particle size desired for manufacturing the sealing member can be separated out.
