Estimation of clay proportions in mixtures by X-ray diffraction and computerized chemical mass balance.

Abstract

A mass balance procedure has been developed from Pearson's approach (M.A. 79-3250) in order to estimate the relative proportions of synthetic phyllosilicate phases present in reaction products. This procedure, which will handle poorly crystallized phases, produces reliable trends in phase proportions that are consistent with XRD data, at a precision of approx 7-25%.-D.F.B.
