Zusammenfassung:Process for making highly pure detrition-resistant boron nitride pressed bodies from a boron-nitrogen-hydrogen compound having the general basic empirical formula BN3-xH6-x, WHERE THE VALUE OF X IS GREATER THAN 1 AND SMALLER THAN 2, WHICH COMPRISES HEATING SAID COMPOUND TO A TEMPERATURE OF 20 DEG TO 2,000 DEG C under a pressure of 0.5-10 t/cm2.
