Modeling of close-range structure in phosphorus-doped alkali-free alumoborosilicate glasses

Computer simulation of the structure of calcium-aluminoborosilicate glass with phosphorus additions showed that its atoms can be located in oxygen polyhedra with different symmetry. Based on calculations of bond lengths and bond angles in phosphate glass-forming polyhedra, a conclusion was made about the most probable structural position of phosphorus in tetrahedra with a P = O bond.
