the effect of deflocculants on the self flow high alumina multifunctional refractory castables
USA1AZS refractory compositionGoogle Patents
A refractory composition includes a first set of components and a colloidal silica binder. The first set of components includes alumina and zirconia. The colloidal silica binder is provided at 5 wt to 20 wt of the dry weight of the first set of components. The refractory composition includes 45 wt to 75 wt alumina 15 wt to 30 wt zirconia and 10 wt to 30 wt silica.
