Formation and characterization of β-and α-Silicon Carbide produced during Silicon/Ferrosilicon process
Jayakumari, Sethulakshmy (Doctoral theses at NTNU;2020:252, Doctoral thesis, 2020)Silicon carbide (SiC) is one of the main intermediate compounds generated during primary silicon (Si) production in submerged arc furnaces. Carbon materials, either biomass-based (charcoal and wood chips) or based on fossil ... -
Graphite crucible interaction with Fe–Si–B phase change material in pilot-scale experiments
Jiao, Jianmeng; Tangstad, Merete; Jayakumari, Sethulakshmy; Wallin, Maria (Peer reviewed; Journal article, 2023)Fe–26Si–9B alloy is a promising high temperature phase change material (HTPCM), due to its high heat of fusion, small volumetric change, abundance, and low cost. Additionally, graphite has been identified as a promising ... -
SiC crystalline micro bullets on bio-carbon based charcoal substrate
Jayakumari, Sethulakshmy; Vullum, Per Erik; Van Helvoort, Antonius; Tangstad, Merete (Peer reviewed; Journal article, 2020)Silicon carbide (SiC) micro bullets were grown on a bio-carbon based charcoal substrate, the morphology and crystal structure were analyzed. In order to collect the crystallographic details scanning electron microscopy ... -
