In this case it is advantageous for the preparation of the anhydrous dibasic calcium phosphate to be so controlled that rounded off crystal aggregates as homogeneous as possible are obtained. If the stabilization is to be carried out on previously isolated anhydrous dibasic calcium phosphate which ...
Corundum forms rounded grains (up to 1 mm across), uniformly dispersed in the main fine-grained mass of hornfelses (Figure 4e and Figure 6a) or long-prismatic crystals (Figure 4e). Iron (up to 0.96 wt.% Fe2O3), Si (up to 0.45 wt.% SiO2), and Ti (up to 0.33 wt.% TiO2) ...
