摘要

In order to study more on the solid solutions existing in the system CaO-Al_2O_3-Fe_2O_3, whose Al_2O_3 : Fe_2O_3 molar ratios are greater than 1, the author has investigated by microscopic and X-ray methods the minerals which exist inthe fired samples of xCaO : 2Al_2O_3: Fe_2O_3 and yCaO : 4Al_2O_3 : Fe_2O_3 (x=5, 6, 7, 8, 10, 15; y=6, 8, 10, 12, 15, 20, 30). The experimental results are as follows: (1) In the xCaO : 2Al_2O_3 : Fe_2O_3 f x=5 and above, the solid solutions contained inthose fired products, are the same withthe principal mineral of 6CaO : 2Al_2O_3 : Fe_2O_3 that was described in the author's previous report (kpart II). (2) In the yCaO : 4Al_2O_3 : Fe_2O_3, the solid solutions, which are contained in those fired products, increase those miscibilities according to the increase of y, and, in y=12, the miscibility reaches to the utmost limti. The solid solution having this maximum miscibility in this series has a higher miscibility than the solid solution of 6CaO : 2Al_2O_3 : Fe_2O_3. (3) In the high elime mix consisting of CaO-Al_2O_3-Fe_2O_3, the addition of SiO_2 has no effect on the composition of the ferrie coxide series solid solution that is made by firing the mix. (4) Accordingly, it can be known that the miscibility of the ferrice oxide series solid solutions, which exist inthe firing products of the higher lime mixes of CaO-Al_2O_3-Fe_2O-SiO_2, increases gradually according to the increase of Al_2O_3 : Fe_2O_3 molar ratio. And the composition of the ferric oxide series solid solution having the maximum miscibility must be approximately 6.2CaO : 2.2Al_2O_3 : Fe_2O_3. (5) Therefore, it is expected that, in the high lime cements, the celite part changes its composition with the variation of the iron modulus; that is to say, in the high lime cements of the iron modulus 1.4 and above, the composition of the ferric oxide seies solid solution existing in the cements is approximately 6.2CaO : 2.2Al_2O_3 :Fe_2O_3, and also, inthe ironmodulus 1.4 and under, the more decreases the ironmodulus, the more decrease the miscibility of the ferric oxide series solid solution existing in the cement (Department of Ceramic Engineering, Tokyo University of Engineering, Tokyo, Japan).
