Abstract
The DSC-DTA combination technique has been used to estimate CaSO[4].2H[2]O, Mg(OH)[2], Ca(OH)[2], CaCO[3] and MgO, comprising three white coat plasters. Unhydrated magnesium oxide could be estimated by converting it to Mg(OH)[2] by autoclaving. An equation is derived from which unhydrated MgO can be determined by substituting the estimated values for CaSO[4].2H[2]O, Mg(OH)[2], Ca(OH)[2] and CaCO[3]. Estimated values of CaO, MgO and CaSO[4].2H[2]O obtained by the DSC-DTA technique correspond closely to those determined by chemical analysis.
