The low-phosphate part of the SiO/sub 2/-Al/sub 2/O/sub 3/-Fe/sub 2/O/sub 3/-RO-R/sub 2/O-P/sub 2/O/sub 5/ system (the system) was examined with a constant content for the sum of the akalis and alkaline earths and with different ratios. The x-ray amorphous state was checked with a diffractometer an the structures were examined by electron microscope using shadowed platinum-carbon replicas and IR spectroscopy. Replacing SiO/sub 2/ by P/sub 2/O/sub 5/ results in a heterogeneous structure; x-ray phase analysis showed that high-alkali compositions had microheterogeneosity due to crystals of phosphates.
