A special sub-set of oxide glasses is called Unconventional Oxide Glass. These oxides do not form glasses alone but can do so in binary or multicomponent mixtures with other oxides such as vanadium oxide, lead oxide, bismuth oxide and some others. The importance of such glasses is found in their interesting properties and application in switching and data storage memories. Therefore, these materials have many useful application in the field of manufacturing of many information technological systems.

A special sub-set of oxide glasses is called Unconventional Oxide Glass. These oxides do not form glasses alone but can do so in binary or multicomponent mixtures with other oxides such as vanadium oxide, lead oxide, bismuth oxide and some others. The importance of such glasses is found in their interesting properties and application in switching and data storage memories. Therefore, these materials have many useful application in the field of manufacturing of many information technological systems. However, this work aimed to prepare a new unconventional transition metal oxide glass system based on both vanadium and iron oxides with the introduction of different strontium oxide concentrations. After successful preparation, some important questions appeared in mind and they have to be addressed. Such questions are: 1- Are these glasses exhibit semiconducting properties in their ac and dc electrical conductivities, or they stay in the dielectric limits?, and What is the origin of the conductivity mechanism? 2- Does these glasses exhibit a Negative Resistance phenomenon or not? 3- What are the roles and the positions in which the used cations occupy in the glass network?
