Thermoanalytical characteristics of powders in dental cast investment

Abstract

The present study examined the thermal properties of phosphate-bonded investments, a gypsum-bonded investment and an experimental investment powder when the basic powders were heated to high temperatures by simultaneous differential thermal analysis (DTA) and thermogravimetry (TG). The phosphate-bonded investments showed values of about 59 kcal mol−1 (247 kJ mol−1) (thermal decomposition of NH4H2PO4) and about 11 kcal mol−1 (46 kJ mol−1) (formation of NH4MgPO4). Thermal reactions occurred clearly on the DTA-TG curves for the investment powders, using powders of NH4H2PO4, and MgO with NH4H2PO4/MgO = 1 as main components in the investment.
