Hollow piece for producing a sintered refractory product exhibiting improved bubbling behaviour |
| 摘要 |
A green part, a region of a refractory furnace or a hollow piece for producing a sintered refractory has the following mean mineral chemical composition in weight percent based of mineral oxides: 40%≦̸Al2O3≦̸94%, 0%≦̸ZrO2≦̸41%, 2%≦̸SiO2≦̸22%, 1%<Y2O3+V2O5+TiO2+Sb2O3+Yb2O3+Na2O. The sintered refractory products obtained from this green part give rise to a reduced bubbling effect. |
