refractory materials in ceramics making process

  • Refractory Ceramics - an overview | ScienceDirect Topics

    2010-6-16 · The refractories industry predates by thousands of years the Bayer process of the 1880s [ 15,16] that made pure alumina ceramics possible, and the first pure alumina ceramic of 1910 [ 17 ]. However, calcined bauxite has been a common component for “high alumina” refractories for a long time.
