Unidirectional (UD) composites, fabricated with surface-oxidized HT carbon fibers (Magnamite AS4, Hercules) and with two mesogenic pitches and two mesophase pitches, were stabilized at 1 MPa oxygen pressure and 200Β°C to various amounts of oxygen uptake, carbonized and graphitization-treated at 2100Β°
Aminoboranes, pure or partially converted into aminoborazines using thermal or aminolysis polymerization, have been used as boron nitride precursors. An amorphous BN preceramic is obtained when pyrolysed up to 1000Β°C that can be stabilized using further annealing up to 1400Β°C or crystallized into h-
