Surface Active Effect of Na2O on the Rate of CO2 Dissociation on the Surface of Molten FeOx-Na2O and FeOx-SiO2-Na2O Systems

“…7. 18,19) Comparing the effect of Na 2 O addition with that of P 2 O 5 reported in the previous paper, 16) the strong promoting effect of Na 2 O is observed, which is different from the strong disturbing effect by P 2 O 5 addition. The difference is considered to be originated with the affinity of Na 2 O or P 2 O 5 and CO 2 molecule.…”

A Model for Estimating the Viscosity of Molten Aluminosilicate Containing Calcium Fluoride

“…In this study, a i and a j in Al were determined from experimental data of the viscosity in binary silicate systems, [6][7][8][9][10][11][12][13][14][15] ternary aluminosilicate systems 7,[15][16][17][18][19][20] and ternary SiO 2 -CaO-CaF 2 systems. [21][22][23] The parameters were deter- (ii) Subsequently the a j in Al value was assessed for each charge-compensating cation j by fitting the calculated viscosity with a i for the binary system as determined in (i) to the experimental data for each ternary SiO 2 …”

A Model for Estimating Viscosities of Aluminosilicate Melts Containing Alkali Oxides

“…In this study, the parameters a i and a j in Al were determined from experimental data in binary silicate systems [25][26][27][28][29][30][31][32][33][34] and ternary aluminosilicate systems. 26,[34][35][36][39][40][41] The way to determine the parameters is as follows: (i) First, the value of a i in each oxide i was obtained from the application of the above equation to fit the experimental values of the viscosity in each binary SiO 2 -(M x O y ) i system, where…”

“…The experimental data [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] used for the determination of these parameters are shown in Table 1, and the assessed parameters are listed in Table 2.…”
