Abstract

The results of studying the process of production of reactive alumina in the presence of a complex additive including polycarboxylate ether (PCE) and polyethylene glycol (PEG) are presented. The effect of such reactive alumina on rheotechnological properties of matrix systems and low-cement refractory casting masses is evaluated. Synergetic effect of combined introduction of PEG and PCE during the process of fine grinding of raw alumina is established. It is shown that the deflocculating effect of polycarboxylate ether and the intensity of the grinding process are intensified.

Keywords

reactive alumina, dispersion, fine powders, deflocculants, polycarboxylate ethers (PCE), polyethylene glycol (PEG),
