This review article analyses the trends in CRM research, popular research topics and tools used in studies. This study presents how CRM research developed over 21 years in terms of critical areas, type of studies, sources of papers, the origin of articles (country-wise distribution), type of data used, under-researched areas and popular researched areas. The study provides a broad classification and summarizes the last 21 years of CRM research in an organized way. For this review article, research papers were taken from January 2000 to June 2020, that is, 21 years. A total of 104 papers were selected from different journals and conferences. Findings show that most of the articles were published in the year 2009. A total of 95% of articles were published in journals, and 5% were conference papers—most of the CRM research done in the USA and the United Kingdom. Empirical papers were maximum ...

The present study investigates the effect of alumina and silica addition on the physico-mechanical and electrical properties of porcelain bodies over high sintering temperatures. The pallets were prepared in different shapes and dimensions with the help of hydraulic press machine by pressing at 160 MPa for a period of 10-min. Different characterizations techniques such as; dilatometer, X-ray diffraction (XRD), and scanning electron microscopy (SEM) used to evaluate the thermal, structural, and microstructural changes, respectively by increasing the concentration of silica (0–20 wt.%) and decreasing alumina (45–25 wt.%) concentration for the base composition of porcelain insulator. The measurement of mechanical strength and physical behavior were analyzed for all the samples prepared with different compositions of alumina and silica with varying sintering temperature (1250 and 1350 °C). The sample with a composition having silica 10 wt.% of alumina 35 wt.% and sintered at 1350 °C, shows the maximum density of 2.55 g/cc with water absorption of 0.94%. This sample also shows the highest value of bending and compressive strength of 129 ± 5 and 202 ± 5 MPa respectively. The highest dielectric value of 5.75 and minimum dielectric loss of 0.05 at a frequency (2–20 GHz) is achieved for the same composition with silica 10 wt.% of alumina 35 wt.% sintered at 1350 °C. The composition having silica 10 wt.% with alumina 35 wt.% sintered at 1350 °C, has enormous potential to serve as a high strength refractory and a dielectric ceramic material for microwave applications.
