Metrology Ceramics for CMM & Motion Control Equipment

Saint-Gobain Performance Ceramics & Refractories offers Silicon Carbide products based on Siliconized Silicon Carbide (SiSiC) and Nitride Bonded Silicon Carbide (NSiC) materials to deliver high accuracy and speed in industrial metrology. Used in CMM and Motion Control Equipment, silicon carbide offers many advantages over traditional ceramic materials.

  • Lightweight (~20% less)
  • High specific stiffness (~25% higher)
  • Low thermal expansion (~50% less)
  • High thermal stability
Saint Gobain Specialty Ceramics' products allow customers to solve tough problems in thermal and chemical processing, industrial metrology, temperature sensing, brazing, mechanical seals, semi-conductor processing, sandblasting, and renewable energy generation applications. Specialty Ceramics' portfolio consists of more than a dozen products, sold as well-known brands: Hexoloy® materials, Norbide® nozzles, Noralide® materials, Silit® materials, Advancer® refractory parts, Alundum® materials, Magnorite®
