Cubic tungsten carbide WC1−x is distinguished by the difficulty of obtaining in a dispersed and bulk form. The article attempts to plasma dynamic synthesis cubic powder method based on use coaxial magnetoplasma accelerator for generating supersonic jet, which then rapidly cooled. possibility with predominant content (up 95%) shown. Studying influence an arc discharge initiation allowed reveal e...

Abstract To investigate the characteristics of graphitized shale and influence organic matter graphitization on gas accumulation, Raman spectroscopy analysis, hydrocarbon generation simulation technique, reservoir physical property test, rock mechanics experiment, field emission scanning electron microscopy (FE-SEM) were carried out nongraphitized shales Longmaxi Formation in Changning area, so...

Studying the dependence of degree (α) and rate (ϑ) phase transformation graphite into diamond on synthesis time at different temperatures developed synthetic diamonds using technology high-pressure high-temperature in a metal melt (HPHT), we determined critical mass diamonds, which indicates entry system stability region graphite, where graphitization occurs. The role implanted metals hydrogen ...

Coal is a carrier of carbon enrichment, so it has the potential for preparation coal-based materials. In this paper, LT anthracite and TSG bituminous coal were selected, corresponding graphitized samples prepared from high-temperature treatment. The effects silicon-containing minerals on evolution during pre-graphitization stage investigated by XRD, Raman spectroscopy, SEM. results showed that ...

Carbon nanotubes (CNTs) have high aspect ratio and have great potential to be applied as the field emission cathode because of its large field enhancement factor. In this work, a high performance carbon nanotube field emission cathode (CNTFC) was fabricated by using a composite plating method. The CNTs were purified by acid solutions and then dispersed in electrobath with nickel ions at tempera...
