| Abstract: | Alumina and magnesia compositions containing additions of titanium, chromium, manganese, iron, and zirconium oxides were sintered in atmospheres of oxygen, nitrogen, and hydrogen. Diffusion promoted by lattice defects was observed by measurements of bulk density. Color, atmosphere, and X-ray diffraction indicated the nature of the structural defects resulting in increased rates of material transport. |
