  • Microstructural Effects on the Mechanical Properties of Hexoloy SA Silicon Carbide (.pdf)
    The flexural strength, fracture toughness and sonic Young's modulus were determined for sintered alpha silicon carbide consisting of various amounts of background porosity and different grain sizes. For the developmental material with average flexural strengths of 380MPa, the flexural strength
  • Sintered alpha Silicon Carbide Some Aspects of the Microstructure - Strength Relationship (.pdf)
    Alpha silicon carbide billets, 98% of theoretical density, were formed by cold pressing and sintering. One half of this fine grain sintered material was further heat treated to induce exaggerated grain growth thus producing a coarse grain micro-structure.
  • Application of WG-300
    with extremely strong, stiff, silicon-carbide crystals, commonly called whiskers. These whiskers are grown under carefully controlled conditions and, due to their high purity and lack of grain boundaries, approach the theoretical maximum strength obtainable. This strength is calculated to be in the order of 1
  • Fixed Abrasives Take Lapping Into Another Dimension
    Traditionally, the grinding. process known as. lapping has been. employed in stock removal of. metal and ceramic workpieces. to achieve a desired concentricity. or "fl atness." Flat. lapping typically involves. a slurry of loose aluminum. oxide, silicon carbide or other. abrasive grains fl owed
  • Bonded Abrasives Basics
    The abrasive materials, ceramic alumina, zirconia alumina, aluminum oxide and silicon carbide, perform the cutting action. An ideal grinding abrasive has the ability to fracture before serious dulling occurs and offers maximum resistance to point wear. Each abrasive has special crystal structure
  • Safety Tips: Grinding Non-ferrous Metals on a Bench Grinder
    At Saint-Gobain Abrasives, we are often asked whether grinding non-ferrous metals on a bench grinder requires a special grinding wheel. We recommend that aluminum oxide wheels be used for grinding ferrous metals and silicon carbide wheels be used for grinding nonferrous metals. However, regardless
  • Grinding out Bottlenecks
    a slurry of loose aluminum. oxide, silicon carbide or other. abrasive grains flowed across a rotating. lapping plate in a water- or oilbased. solution. By creating an abrasive. "film" between the plates and the. workpiece, stock removal from a single. side, or both sides simultaneously,. can
