Енергозберігаюча технологія отримання вогнетривких матеріалів системи Al₂O₃– SiO₂– Cr₂O₃ із cамотвердіючих мас

Abstract

For the given it is of practical interest of the Cr₂O₃ addition influence upon the alumina crystal growth inhibition as well as on the chromium solid solutions formation in the electrical alumina – SiO₂ soot (from ethylsilicate binder) system. The correlation composition – structure – properties is studied. The task is: to complicate the complex electrical alumina – ethilsilicate binder – Cr₂O₃; to carry out the thermal treating; to study the conditions of predetermined microstructure and phase composition for the getting of items with polyfunctional purposes in order to extend their fields of usage in different industrial branches
