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 5):
Process for preparing a refractory composite material according to  claim 4 , wherein, in step a) of mixing in water:\n the melted alumina and/or the tabular alumina is present in a percentage ranging between 60 and 72 wt %, more preferably between 65 and 68 wt %, the reactive alumina is present in a percentage ranging between 10 and 20 wt %, more preferably between 13 and 17 wt %, the microsilica (MS) and/or the colloidal silica is present in a percentage ranging between 6 and 10 wt %, more preferably between 7 and 9 wt %, the flux oxides are present in a percentage ranging between 2 and 4 wt %, more preferably between 2.5 and 3.5 wt %, the inorganic dispersant additive based on SiO 2  and Al 2 O 3  is present in a percentage ranging between 1 and 1.5 wt %, more preferably between 0.6 and 0.8 wt %, the inorganic accelerating additive based on SiO 2  and Al 2 O 3  is present in a percentage ranging between 0.6 and 1.2 wt %, more preferably between 0.6 and 0.8 wt %, the inorganic toughening or mechanic reinforcement additive based on SiO 2  and Al 2 O 3  is present in a percentage ranging between 2 and 4 wt %, more preferably between 2.5 and 3.5 wt %, the organic dispersant additive comprising polymer material based on polyethylene glycol is present in a percentage ranging between 0.07 and 0.1 wt %, more preferably between 0.06 and 0.08 wt %, the organic de-airing additive comprising alkoxylated fatty alcohols and polysiloxanes on inorganic medium is present in a percentage ranging between 0.02 and 0.1 wt %, more preferably between 0.03 and 0.06 wt % the remaining part being water, said percentages being calculated on 100 parts by weight of the resulting slurry.
