BONITE - A NEW RAW MATERIAL ALTERNATIVE FOR REFRACTORY INNOVATIONS

摘要

In the current paper, Bonite is introduced as a new synthetic dense refractory aggregate based on the mineralogical phase calcium hexaluminate, CA6. The paper discusses chemical and physical properties of both, the new raw material and different test castables based on Bonite, tabular alumina and combinations thereof. Advanced tests like aluminium resistance, thermomechanical properties, thermal conductivity, resistance in carbon monoxide atmosphere and microporosity are discussed in respect of application areas for Bonite.
