Qsil Ceramics - Forming and Welding Technology

Material properties for forming and welding technology:

  • High hardness
  • High bending strength in combination with good fracture toughness
  • Extremely wear resistant and corrosion stable
  • No affinity to cold-welding
  • Extremely good thermal shock resistance
  • Very high stiffness
  • Temperature stability exceeding 1000 °C
  • Very low CTE
  • Electrically insulating or conducting properties
  • Low density
  • High and constant surface quality of the welded product

In forming and welding technology our Silicon Nitride materials are already evaluated or state of the art in many applications.

FCT Ingenieurkeramik with its economical production technology is in the position to manufacture customized components with high complexity and narrow tolerances as prototype or in series production.

Diameters up to 450 mm and lengths up to 1300 mm are state of the art.

Powder compaction takes place via cold isostatic or uniaxial pressing of semi-finished parts and subsequent turning or milling treatment in green state as well as via conventional slip casting. Additionally also extrusion and injection molding are available.
