More Information
Summary:The invention relates to an unshaped refractory compound, in particular a casting compound, gunning compound and/or free-flowing compound, comprising a bond system, which forms upon addition of water, and a dry micro-scale amorphous SiO2- binder as the sole binder, which is mixed in a proportion of ≤ 1% by weight of the total mass with the solid components to be bonded and forms the bond system after addition of 1-30% by weight of water. The invention further relates to a method for producing refractory compounds and a use of microcrystalline amorphous silicon dioxide in the production of refractory compounds.
