Gallium ( III ) sulphide on its own is not a known glass former; however, with sodium or lanthanum sulphides it forms a glass, gallium lanthanum sulphide ( GLS ).

The alloys of boron, silicon, phosphorus, and other glass formers with magnetic metals ( iron, cobalt, nickel ) have high magnetic susceptibility, with low coercivity and high electrical resistance.
13.
Instead of the SiO 4 tetrahedra observed in silicate glasses, the building block for this glass former is phosphorus pentoxide ( P 2 O 5 ), which crystallizes in at least four different forms.
14.
The otherwise acidic pentoxide Sb 2 O 5 shows some basic ( metallic ) behaviour in that it can be dissolved in very acidic solutions, with the formation of the oxycation SbO . The oxide Sb 2 O 3 is polymeric, and a glass former.
15.
Although by itself Ga 2 S 3 is not a glass former it can be reacted with rare earth sulfides to form glasses e . g . the reaction with lanthanum sulfide, La 2 S 3, forms gallium lanthanum sulfide glass which has interesting optical properties and is a semiconductor.
