Abstract:On the raw material system consisting of potassium feldspar, phosphogypsum and calcium carbonate with the mole proportion n ( KAlSi3O8 ) : n ( CaSO4·2H2O ) : n ( CaCO3 ) = 2 : 1 : 6, the effects of several inorganic aids on the above-mentioned system decomposition temperatures are studied by using differential thermal analyzer (DTA) . The results show that NaF has a positive role.
Keywords:potash feldspar  phosphogypsum  calcium carbonate  decomposition temperature  inorganic aid
