Momentive Performance Materials HCR48 Boron Nitride (BN) Powder
Categories: Ceramic; Nitride; Other Engineering Material; Additive/Filler for Polymer

Material Notes: GE Advanced Ceramics boron nitride (BN) powder grades HCR48, HCJ48, and HCM are large, high-density agglomerates, of ~10 µm crystals, with average particle sizes between 175-275 µm and tap densities of ~1 g/cm3. These features, combined with low average surface areas, give powders that flow readily, withstand harsh processing, and have outstanding thermal characteristics.

HCR48 has an average particle size of 250 µm and is the highest density (hardest) grade offered by GE Advanced Ceramics. It has higher oxygen and soluble borate levels than most grades, which limits its performance in high-temperature (>550o C) applications.

Information provided by Momentive Performance Materials, formerly GE Advanced Ceramics.
