Abstract:
This paragraph deploys high temperature non-vacuum methods, and vanadium pentoxide powder, carbon black and graphite is used to make VN. The result shows that the particle sizes of these three raw materials vary greatly. When they are mixed with a certain proportion, the kinetics condition of reaction is greatly improved. when the vanadium pentoxide powder enters agglomeration level(1490°C) after it has been reduced and nitrided, agglomeration time has small effect on the reaction process and chemical composition of product. On the contrary，if the agglomeration time lasts too long, it will gen

Abstract:
Single-crystal V2O5 nanowires were successfully synthesized from the starting materials V6O13 powder and water. The experimental results indicate that high purity nanowires can be obtained using this simple synthetic route in absence of templates or catalysts. The diameter of the nanowires was found to be ca. 20∼60 nm and the length up to several tens of micrometers, and the phases of nanowires were determined by XRD and TEM measurements.

Методами термогравиметрии, дифференциальной сканирующей калориметрии, рентгенофазового анализа и электронной микроскопии исследованы особенности окисления порошков аморфного бора, модифицированных пентоксидом ванадия. Модифицирование осуществляли путем смешения порошков с ванадийсодержащими гелями — гидрогелем состава V2O5 · nH2O и олеогелем состава V(OCH2)2 · n(HOCH2)2. Установлено, что добавление к порошку аморфного бора 2 % (мас.) V2O5 на 200 °C снижает температуру начала его интенсивного окисления и на 25 % повышает удельное тепловыделение в процессе взаимодействия при нагревании на воздух

The composite solution was deposited on a dielectric substrate with copper electrodes and the Cu/PEPC-V2O5/Cu surface type film samples were fabricated. The Cu/V2O5/Cu samples were used as a reference where the films were deposited from the mixture of V2O5 powder in distilled water. Resistance-temperature relationship and voltage-current cha

Abstract:
Converter vanadium slag is a byproduct of the iron making process when the vanadium titanomagnetite is used as iron raw material. A cleaner process including calcified roasting, dilute acid leaching, precipitation purification, vanadium precipitation with ammonium salt, followed by thermal decomposition was proposed to extract vanadium resource from this slag. And then vanadium pentoxide with purity over 98% was prepared, which can be used as additives for high strength low alloy steel production. A total vanadium recovery beyond 80% was achieved in this whole process. Since no sodium and pota

Abstract:
Environmental regulations are very stringent in the U.S., requiring very low emissions of nitrogen oxides (NOx) from combined cycle power plants. Selective Catalytic Reduction (SCR) systems utilizing vanadium pentoxide (V2O5) as the active material in the catalyst are a proven method of reducing NOx emissions in the exhaust stack of gas turbines with heat recovery steam generators (HRSG) to 2–4 ppmvd. These low NOx emissions levels require an increase of SCR removal efficiency to the level of 90+ % with limited ammonia slip. The distribution of flow velocities, temperature, and NOx mass flow a
