“…One of the factors that affects conductivity, in the small polaron hopping model of conduction used in vanadate glasses, is the ratio of oxidation states of the vanadium ions . Measurement of the V +4 /V total ratio can be obtained by redox titrimetry . For this technique, the glass was crushed into a powder, and a known quantity was dissolved in sulfuric acid.…”

Particle detectors are constantly being built and refitted with new technology to improve the spatial resolution, radiation hardness, and speed at which the detector can capture particle events. One of the most crucial components of a modern collider experiment is the hadron calorimeter. One of the proposed improvements on future hadron calorimeters is to utilize resistive plate chambers (RPCs). They provide the spatial and energy resolution as well as could provide speed and radiation hardness. RPCs depend on manufacturing electrically conductive glasses that are mechanically strong, durable, radiation resistant, and not ionically conductive. To achieve such requirements, vanadate glasses were developed as alternatives to current prototypes which use soda lime silicate glasses. The conductivity, oxidation states of vanadium, radiation hardness, as well as the prototype performance, were tested on vanadate glasses. The prototype tests show that using 0.40ZnOÀ0.40TeO 2 À0.20V 2 O 5 can improve the RPC detector rate up to 100 times.

“…The structure of Bi-Sr-Ca-Cu-O glasses was studied by Khaled et al [2]. Both Bi and Cu cations are considered as glass formers and it has been shown that a glass network is created by Bi 3+ and Cu 1+ ions, with Bi ions coordinated by 6 and Cu ions by 2 oxygen atoms.…”

In the (Bi,Pb)-Sr-Ca-Cu-O system, materials of various electrical and superconducting properties may be produced by a glass-ceramic method. Phase composition, structure, microstructure and also electrical properties of the material change as a result of heat treatment. Depending on the heat treatment conditions, either a superconductor with the critical temperature between 8 and 105 K or material without a superconducting transition may be obtained. The properties of the material change so much because during annealing three oxide superconductors belonging to the bismuth family are formed. (Bi 0.8 Pb 0.2 ) 4 Sr 3 Ca 3 Cu 4 O x glass was prepared by a standard technique of quenching homogenized and melted substrates. The glass--ceramic samples were obtained by annealing of the glass beneath melting temperature. Structure and microstructure of glass-ceramic samples were studied with scanning electron microscopy and X-ray diffraction method. Superconducting properties were studied by means of electrical conductivity and magnetization measurements. In this paper we present the influence of the phase composition, structure and microstructure on the electrical conductivity in the normal state and the superconducting properties of (Bi,Pb)4Sr3Ca3Cu4Ox glass-ceramics.

“…Various mechanisms of superconducting phase development have been reported in the literature [17][18][19][20][21]. The crystallization kinetics of BSCCO systems have been investigated by using DTA, differential scanning calorimeter (DSC) and TG methods and the crystallization activation energies, Avrami parameters, and the average oxidation rates of these systems have been calculated [11][12][13][14][22][23][24].…”
