Abstract:
Refractory composite material based on Al 2 O 3  in the form of corundum, SiO 2  in the form of quartz and sodium aluminate having the formula NaAl 11 O 17  or Na 2 O-11Al 2 O 3 , method for preparing the same, use thereof for preparing manufactured items, as well as manufactured items made thereby and use thereof.

Claim (Index 14):
Method for preparing a manufactured item comprising a refractory composite material based on Al 2 O 3  in the form of corundum, SiO 2  in the form of quartz and sodium aluminate having the formula NaAl 11 O 17  or Na 2 O. 11Al 2 O 3 , said method comprising the following steps:\n a) mixing in water, under continuous stirring, in the presence of an organic dispersant additive comprising polymer material based on previously dissolved polyethylene glycol: microsilica (MS) and/or colloidal silica, with flux oxides along with: an inorganic dispersant additive, an inorganic accelerating additive and an inorganic toughening additive, all based on SiO 2  and Al 2 O 3 , as well as an organic de-airing additive comprising alkoxylated fatty alcohols and polysiloxanes on inorganic medium, followed by the addition, always under stirring in water, of reactive alumina and melted alumina and/or tabular alumina, to form a slurry; b) casting the slurry obtained in step a) in vibrating moulds or receptacles; c) \u201cGel-bonding\u201d after casting in the moulds the slurry obtained in step a), followed by stripping and cross-linking through following treatments of: drying at ambient temperature 20-24\u00b0 C. for 8 hours; following heat treatment with average gradient of 50\u00b13\u00b0 C. for densification and the formation of stable bonds at 700-800\u00b0 C. in a moderately oxidizing environment, wherein the mould or receptacle in step b) is made of silicone.
