摘要 |
1. A refractory thixotropic self-hardening vibration compound on a zirconium silicate base for producing a vibration density of at least 3.5 g/cm3, characterized by the following chemical composition (in % by weight) : 20 to 30% SiO2 20 to 45% Al2 O3 0.7 to 1.4% TiO2 0.2 to 0.8% P2 O5 0 to 1.5% K2 O+Na2 O+LiO2 0 to 1.0% Fe2 O3 0 to 0.05% CaO residue ZrO2 and having the following base refractory materials (in % by weight) : 25 to 50% sintered bauxite 1 to 10% alumina 0.1 to 3.0% amorphous silica 0.3 to 1% aluminium metaphosphate 0.5 to 4% alkali silicates having a molar ratio of 1:2 to 1:4 residue zirconium silicate and the following grain fraction : 20 to 35% : up to 0.06 mm 25 to 60% : 0.06 to 0.5 mm 5 to 55% : 0.5 to 5 mm. |
