Refratechnik hybrid castables:
Also suited for low temperatures.
The technology of cement-free Sol-Gel-bonded refractory castables makes another step forwards. Our new hybrid castables permit fast heating combined with high strength – also at low temperatures.
This offers advantages in the production of prefabricated components or the lining of e.g. fluidized bed furnaces and refuse incineration plants.

Advantages of hybrid castables
compared to conventional cementitious materials:
- Faster heating up with shorter downtimes
- Cost and energy-saving
- Very good adherence on existing refractory materials
- Installation possible on hot surfaces and with high ambient temperatures
- Higher application temperature limits
- Optimized thermomechanical behaviour
- Long storage life of 12 months
- Increased cold crushing strength and modulus of rupture as well as optimized abrasion resistance in the temperature range below 1000 °C.
