摘要：A refractory moulding, comprising an alpha -Al2O3, beta -Al2O3, calciumhexaaluminate (CA6) and calcium dialuminate (CA2) phase mixture, is new. A refractorymoulding comprises a mineral oxidic component which has the composition (by wt.) 80-99% Al2O3, 1-20% CaO and 0-5% usual impurities and which is formed of an alpha -Al2O3,beta -Al2O3, calcium hexaaluminate (CA6) and calcium dialuminate (CA2) phase mixture.Independent claims are also included for the following: (i) a mix, especially for producingthe above refractory moulding; (ii) a process for producing the above refractorymoulding, especially using the above mix; and (iii) use of the above mix for production ofpressed or rammed mouldings or as a rammable, sprayable or repair material.
