Background: Radioactive yttrium glass microspheres are used for liver cancer treatment. These yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. There are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall...

Excavations in the Roman villa of Aiano yielded twenty glass beads, a pendant, and glass-recycling furnace, originally interpreted as bead workshop. This article re-assesses evidence making light new data obtained thanks to recent progress archaeological studies. A detailed study typology, technology, chemical composition beads clearly excludes local production. Instead, two different forming t...

Hybrid Concrete focused on the development of buildings, highways, and other structures of civil engineering. In the current study, various mix combinations have been prepared and tested with different percentages of super-plasticizer at different levels of water reduction for obtaining the optimum mix. Further, study on different properties of hybrid concrete and replacement of ordinary portla...

Intensified environmental regulations have posed numerous challenges in the disposal of industrial wastes. The steel industry is one of the biggest production industries, with a considerable amount of daily wastes. Production of glass-ceramic from the steel industry waters is one of the proper solutions for this problem. In this study, the application utilization of different wastes (such as bl...

In order to improve the chemical stability and modify the biodegradability of bio-glass ceramics materials for certain applications, a correlation between structural and biological properties of bio-glass ceramics is very essential and these properties are found to be greatly dependent on the composition and synthetic parameters of the material. In the present work, an attempt has been made to ...

In this paper, the influence of water glass types, modulus glass, alkali content, consumption, and plant fibers on mechanical strengths alkali-activated blast furnace slag powder (BFS) is investigated. Moreover, fiber types pretreatment measuring temperature performance BFS are further considered. Results indicate that activated by potassium silicate shows higher than sodium silicate. The with ...

Abstract In this study, Sn-doped 10HfO 2 –10Al O 3 –80SiO glasses were prepared using a xenon imaging furnace and their physical, optical, scintillation properties investigated. At the composition ratio, specimens did not completely vitrify, they crystallized that contained nanocrystals of c-HfO . Raman spectra show absorption bands due to Si–O–Hf bonds, band clearly indicated an effective mole...

Since Priestley utilized the radiant energy of the sun with his burning glass in his famous experiment of 1774, the method has fallen into disuse and the chemist has accepted the water-bath, the hot-air oven, and the furnace as the standard tools for evaporation, drying, and combustion. The boiling water-bath is used for evaporating solutions or drying solids which decompose at temperatures sli...

An overview of the successful application modern composite materials for manufacturing turbine blades aircraft gas engines, axial mine and blast furnace compressors. Their main advantages these in comparison with metal are analyzed. Analytical calculations stresses arising material plastic starting turboexpanders carried out. The possibility glass-filled polyamide moving guide their operation a...

A mathematical heat transfer model for the prediction of transient heating of the slab in a direct-fired walking beam type reheating furnace has been developed by considering the nongray thermal radiation with given furnace environments. The furnace is modeled as radiating nongray medium with carbon dioxide and water with five-zoned gas temperature and the furnace wall is considered as a consta...
