Machinable porous silica

Cotronics® Rescor® 310M Foam is composed of over 99% pure fused Silica Ceramic and withstands temperatures to 1650°C.

310 Ceramic Foam features low thermal expansion, high thermal shock resistance, low thermal conductivity and  high thermal reflectance.

It is resistant to oxidizing and reducing atmospheres, molten metals, steam, corrosive  gases, most acids, chemicals and solvents. Does not contain organics and will not out-gas  in vacuum atmospheres. White Hot, 1000°C, Ceramic Foam parts can be  immersed in water without cracking.

Rescor® 310M is easily cut, sawed and drilled. Can produce highly detailed parts with unique properties suitable for many applications.

Applications

  • Miniature heater forms
  • Heat reflectors
  • Instrumentation parts and assemblies
  • Radiant heater panels
  • Severe thermal shock applications
