Process changes iterated under guidance of x-radiography. In recent work at NASA Lewis Research Center, density gradients in sintered silicon nitride, characterized by x-radiography, identified and appeared strongly dependent upon powder-processing and sintering conditions. NASA technical memorandum describes systematic investigation, based upon preliminary work, of density-gradient/flexural-strength relationships as affected by processing.
