Suspensions of a powder mixture of titanium-titanium oxide-nickel oxide were tape cast. Analysis of the green tape showed an increase in Young's modulus and tensile strength with increasing powder volume content φ up to 28 vol%; at higher φ the properties decreased due to the formation of flaws in t
## Abstract Diffusion rates were measured at 25°C and 1 atm by a steady state method in pellets of nonporous nickel oxide particles in order to determine the effects of sintering and chemical reduction. Sintering led to a striking decrease in diffusion flux; tortuosities above 100 were found for hi
