prepared the machineable glass-ceramics via ([P.sub.2] [O.sub.5]) as glass former with (Ti[O.sub.2]) as a doping material [13], Sutatipstudied the effect of adding (CaO) on the thermal parameters, physical properties, phase formation and microstructures properties of ([P.sub.2][O.sub.5]-CaO-[Na.sub.2]O) glass ceramics[12].
Meanwhile, boron oxide is an excellent glass former that owns the ability to exist in both three and four coordinated environments, has high strength of covalent B-O bond, is able to form stable glasses, and has high potential to be designed as new optical devices because of their good rare earth ions solubility [6, 7].

They found that the Zn cation can act both as network modifier and network glass former. ZnO enters the network with Zn[O.sub.4] structural unit as a glass forming oxides while octahedrally coordinated as network modifier.
The amorphous metal used in the HV MAX core contains ferromagnetic elements alloyed with a glass former. These materials have high magnetic susceptibility, with low coercivity and high electrical resistance.
In this work, we have shown that the incorporation of MMT leads to decrease the amount of vitreous phase able to relax at the glass transition, accelerate the kinetics of relaxation of this vitreous phase, make stronger the liquid glass former and do not modify the [beta]-relaxation.
This research focused on testing higher wastes loading of Sludge Batch 2 (SB2) simulant using Frit 320, a newly developed glass former. The objective of this research was to determine how increased waste loading affects melting behavior, melt rate, and waste throughput.
Since Te[O.sub.2] is conditional glass former, BaO is introduced to stabilize the glass matrix.
They can be added to glass former like [B.sub.2] [O.sub.3] to enhance their properties [6].
The presence of two network forming oxides, the classical [B.sub.2][O.sub.3] and the conditional [Bi.sub.2][O.sub.3] glass former, the possible participation in the glass structure of both boron and bismuth ions with more than one stable coordination (and, thus, the presence of several structural units namely, B[O.sub.3], BO4, Bi[O.sub.3], and Bi[O.sub.6]), the capability of the bismuth polyhedra and of the borate structural groups to form independent interconnected networks [4].
From the above discussion, to suppress precipitation of enriched Al phases and get better glass former, we can decrease the coefficient of c in (1) to c = 3.5/16, while a and b increase to a = b = 6.25/16.
Borate compounds have been widely studied due to their features as glass formers and also on account of being very advantageous materials for radiation dosimetry application as discussed elsewhere [1, 2].
