Abstract: The phase coexistence in the concentration part CaO—-MgO—2MgO • Si02—2CaO • Si02—2CaO • Na20 • Р205 of the system CaO—MgO—Si02—Na20—P205 was determined at subsolidus temperatures, i.e. the
elementary tetrahedra in the system were defined. The crystalline phases
present were identified by the X-ray powder diffraction.
The only phosphate phase in the system is CaNaP04 , which forms solid
solutions with adjacent silicate phases at high temperatures and which is
responsible for bonding properties in the basic refractory materials from
the phosphate bond point of view.
