Diffusion Studies in Nonmetallic System. Part II. Diffusion of 51Cr in MgO and Cr-Doped MgO.
Abstract
The diffusion coefficient of 51Cr as a function of temperature for arc grown a vapor deposited MgO-crystals with aliovalent impurity levels of 250 ppm can be expressed in equation form. The value of the activation energy for diffusion was found to be close to the interdiffusion activation energy in the system MgO-Cr2O3. Single crystals of Cr-doped MgO with Cr2O3 concentrations up to 0.348 mole % were grown by an arc fusion technique. Crystal size was approximate 3 x 3 x 5 mm. Diffusion coefficients of 51Cr in Cr-doped MgO indicated a linear increase with increased mole % of Cr2O3 to 0.348 mole %.
