Coarse-Refractory Spinel Particles Suitable for Elastication of Ceramic Refractory Products, Processes and Use Thereof

摘要

FIELD OF THE INVENTION The present invention relates to granular, refractory inorganic elastomeric particles for refractory products, particularly basic refractory products, MgO: 12 to 19.5, specifically 15 to 17% by weight, Balance: Fe ₂ O ₃ and Al ₂ O ₃ are in a composition range of Fe ₂ O ₃ and Al ₂ O ₃ in a content ratio of 80:20 to 40:60% by weight and have a total composition of 100% based on the MgO content in% by weight, individual mixed crystal is one of the ternary _{MgO-Fe 2 O 3 -Al 2} O 3 having the content of the Fe ₂ O ₃ and Al ₂ O ₃ solid solution in each given range - phase melt spins mixed crystals or multi-phase melt products. The present invention also relates to a process for producing elastic particles and a use thereof.
