Carbon Bonded Carbon Fibre

Rigid Thermal Insulaton for Vacuum & Atmosphere Controlled Furnaces

Calcarb for Vacuum Furnaces

Calcarb has extensive machining facilities and can supply cylinders, discs, boards and special shapes to suit most furnace lining configurations. Coated and foiled products are all re-fired prior to despatch and can also be halogen purified to total ash level of <20ppm.

Calcarb's product acts as heat shield (i.e. insulation lining) with very refractory properties. It is capable of withstanding temperatures of up to 3000°C. It is chemically inert except under oxidising atmospheres above 450°C, and certain gases at higher temperatures.

Calcarb insulation for
Crystalline Growing

It is manufactured by a process that eliminates outgassing under vacuum conditions (all Calcarb's base material is fired to 2000°C and outgassed under vacuum). It has a very low thermal conductivity value, and its thermal and erosion resistance can be enhanced by coating with graphitised foil, graphitised paint or specialist high density coatings applied by CVD process.
