In this thesis aluminate glasses have been made using aerodynamic levitation and laser heating techniques. Three sub-systems are studied in detail. First the structure of (Nd₂0₃)o.₃₇₅(Al₂0₃)o.₆₂₅ (Nd₃Al₅0₁₂) glass was measured by neutron and x-ray diffraction techniques at the first order difference level. Using this data full structural models consistent with the diffraction measurements were made. From these Nd₃Al₅0₁₂ glass is found to consist of predominantly tetrahedral AlO, with on average 0.8 non-bridging oxygen per tetrahedron. The Average Nd-0 coordination is found to be 7.0(2), which results form a combination of 6.2(2) Nd-0 at 2.42(4)A and a further 1.2(2) Nd at 2.7(4)A, No significant amount of Nd-0 is found at the longer 2.91A crystal structure distance.
