Analyses and Characterization of Fossil Carbonaceous Materials for Silicon Production
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:30, Doctoral thesis, 2008)Production of high silicon alloys is carried out in submerged arc furnaces by reduction of silicon bearing oxides (typically quartz) with carbon materials. Carbonaceous materials like coal, coke, charcoal and woodchips are ... -
Solid solubility and phase transitions in the system LaNb1-xTaxO4
(Journal article; Peer reviewed, 2008)The solid solubility between LaNbO4 and LaTaO4 was investigated by X-ray diffraction, and a two-phase region was observed in the composition region LaNb1−xTaxO4 where 0.4⩽x⩽0.8. Single-phase LaNb1−xTaxO4 (0⩽x⩽0.4) with the ... -
Oxygen stoichiometry and transport properties of cerium niobate
(Journal article; Peer reviewed, 2008)CeNbO4 + δ has been synthesized by both solid state and wet chemical routes and characterized with respect to electrical conductivity and oxygen stoichiometry between 900 °C and 1100 °C and pO2 from 1 bar to 0.002 bar. ... -
