Iron leaching from nonrefractory grade bauxite: Individual process optimization and prediction by using DOE

open access: yesInternational Journal of Ceramic Engineering & Science, 2022
Bauxite is an important raw material for the production of refractories. The availability of refractory grade ore worldwide is limited, and high iron contents in particular reduce the quality of the material.

Experimental Investigation of the Tension and Compression Creep Behavior of Alumina-Spinel Refractories at High Temperatures

open access: yesCeramics, 2020
Refractory materials are subjected to thermomechanical loads during their working life, and consequent creep strain and stress relaxation are often observed. In this work, the asymmetric high temperature primary and secondary creep behavior of a material
