Polyimide precursors and polyamic acid were synthesized by direct polycondensation reaction of the 1,2,3,4-butanetetracarboxylic acid (BTCA) and diamines in the presence of metal salts and phosphorous compounds. The BTCA was reacted with an initiating species, which is the phosphonium salt of metal
Slag+metal) equilibrium experiments have been made for the determination of activity of MgO in the {(1-x)MgO+xB2O3} binary slag at the temperature T=1723 K, using germanium as metal solvent. The activity of B2O3 was calculated analytically from the Gibbs-Duhem equation.
Slag+metal) equilibrium experiments have been made for the determination of activity of B2O3 in the {(1-x)MgO+xB2O3} binary slag at the temperature T=1723 K, using copper as metal solvent. The independently measured activities of B2O3 reported in this study and of MgO reported in a previous paper in
Slag + metal) equilibrium experiments have been carried out for the determination of activity of MgO in the {(1x)MgO + x(1y)B2O3 + xySiO2} ternary slag at the temperature T = 1723 K, using germanium as metal solvent. The results are compared with the isoactivity curves of MgO determined previously.
Slag + metal) equilibrium experiments have been made for the determination of activity of SiO2 in the {(1x)B2O3 + xSiO2} slag at the temperature T = 1723 K, using (0.25 Cu + 0.75 Sn) as a metal solvent. The results indicate a positive deviation from ideality. The activity of B2O3 was calculated from
