Abstract
In this study, sintering experiments were carried out on SrO-CaO-ZnO-Al2O3-B2O3-SiO2-TiO2 glass system with varying temperature, time and heating rates. The density of samples increases with the increase in temperature from 750 to 850?C. Thereafter, significant improvement in density is not noticed. The dwell time and heating rate have no marked impact on the improvement in density. From 850?C onwards, samples exhibit the peaks of crystalline phases confirmed by XRD. SEM images show the progressive increase in the compactness of microstructure with the reduction in porosity. The increase in HV with the increase in sintering temperature is attributed to the simultaneous increase in density. The highest hardness was obtained for the sample sintered within 850-950?C for 1h and a heating rate of 8?C/min. The Young's modulus is found to be of similar trend, like hardness. The CTE of annealed and sintered glass is 10.2 ? 10?6 and 9.8 ? 10?6/?C, respectively.
期刊介绍：
Science of Sintering is a unique journal in the field of science and technology of sintering.
Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published.
Science of Sintering journal is published four times a year.
Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
