Potassium disilicate

As previously discussed, both potassium tetrasilicate and potassium disilicate melt congruently at 770 2°C and 1045 2°C, respectively. Both compounds crystallize readily from appropriate melts when no potash feldspar crystals are present. In the region of the boundary curve between the tetrasilicate field and potash feldspar field, it is possible to follow the metastable extension of the potassium tetrasilicate liquidus surface beneath the stable potash feldspar field. Near the boundary curve between the disilicate field and the potash feldspar field, a metastable extension of the disilicate liquidus surface beneath the stable potash feldspar field is also possible providing once again that no potash feldspar crystals are present. [Pg.57]

A new type of mixed cation disilicate has been reported by Ragimov et al. (1980). Besides univalent potassium, the compound contains divalent cobolt, leading to the formula KHoCoSi207. The crystals have been prepared at high pressure. The structure is monoclinic and differs from the structure of the ternary alkali rare earth disilicates. [Pg.269]

Corresponding negative ion FABs do not provide any useful information as matrix interactions predominate obscuring all oAer peaks. Unfortunately, high resolution mass spectral analysis did not confirm the proposed structure. As shown in Table III, the exact mass analysis of the molecular ion peak corresponds to that of the disilicate structure with a potassium counterion, rather than the proposed protonated trimetallic double alkoxide structure. [Pg.143]
