Triangular compositional diagram

Figure 5.6 Triangular composition diagram for SiO -Alj Oj-CaO glasses, showing that glasses with cement-forming ability fall within the gehlenite and anorthite composition region, and that only glasses with less than 61 to 62% by mass of silica have the potential to form a cement (Hill Wilson, 1988a).

Figure 5.7 Triangular composition diagram for SiOj-Al Oj-CaO glasses. Glasses in the gehlenite region yield stronger cements (95 to 104 MPa in compression) than those in the anorthite region (29 to 56 MPa) (Hill Wilson, 1988a).

In general, m is not independent of composition, and often the solvents A and B show partial miscibility. Ternary equilibrium data of this type may be shown on a triangular composition diagram (Fig. 2). It will be seen that in parts...

Hypersaline fluid inclusions were observed as isolated inclusions in zone I. These inclusions contain one halite cube. Eutectic temperatures are very low (< -48 C) indicating the presence of divalent cations (Ca and Mg ). The inclusions homogenise to the liguid between 270° and 300 °C. Th-tot values are in most cases lower than the halite melting temperatures, which occurs from 300° to 320° C. Salt content has been estimated using the triangular composition diagram of Vanko et al. (1988). The fluid composition is 30 -40 % NaCl, 6 -10 % CaCU and 50 - 64 % HjO. 

It is claimed that ultra-high modulus fibres can be made from those compositions which fall within a defined area when plotted on a triangular composition diagram for the three types of repeat unit. These workers have, in effect, mixed together various combinations of the bifunctional...

One mole each of CO2 and O2 are placed in an evacuated container. A catalyst causes equilibrium in Reaction 15.C to occur. Only the gas phase is present. Is there a stoichiometric restriction in the application of the phase mle to this system Are there more than one If there is (are) write the appropriate equation(s) of the restriction(s), and sketch it (them) on an appropriate triangular composition diagram.
