  • Boron Carbide an overview ScienceDirect Topics

    Boron carbide (B 4 C) is one of a number of boron/carbon compounds, but is the one most frequently used as a ceramic material It is perhaps the hardest of materials which can be processed as a conventional ceramic, and its applications are concentrated where hardness is the principal requirement, including grit blasting nozzles, bearings

  • Boron carbide │ Technical ceramics

    Boron carbide powder is a starting material for sintering and hot pressing in the manufacture of boron carbide sintered parts In this form it can be found, among other things, in dressing and grinding stones and as a lining for ball mills and mortars Boron carbide powder is also used as a sintering additive for highperformance SiC ceramics

  • Crystal structure: Rhombohedral
  • A Novel method of synthesis of high purity nano plated

      Nano plated and highpurity boron carbide (B 4 C) powder was synthesized via a novel method, based on a solidstate reaction of poly (vinyl alcohol) PVA and boric acid at (200–250) °C in air The crosslinking between PVA and boric acid was proven by FTIR analysis The obtained product, a newtype of poly vinyl borate (PVBO), was consecutively pyrolyzed at (700–800) °C for 120 min in air
