Synthesis of HfB2 Powders by Carbothermal Reduction
In this research, solid state carbothermal synthesis of HfB2 Nano powders was investigated. For this purpose, HfO2,H3BO3, carbon active or phenolic resin were used as raw materials for carbothermal reaction. After 2-4 hours of milling the raw materials by a planetary ball in an ethanol media, the mixture was heat dried and pressed in to disks under pressure of 20-30 bar. The disks were then pla...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولRoute to GaN and VN assisted by carbothermal reduction process.
A route to prepare nitrides, such as GaN, VN, and other nitrides, is reported. The reaction pathway involves a two-step process by using the as-synthesized a-C3N3.69 as precursor. The route is so potent that a series of nitrides can be directly synthesized from their oxides at moderate temperatures. A striking feature of this method lies in that a-C3N3.69 is found to play double roles as both c...
متن کاملIn Situ Investigation of the Carbothermal Reduction of ZnO Nanowires
Carbothermal reduction is among the oldest chemical processes, commonly used in the production of metals from the corresponding metal oxides or ores (e.g., iron from iron oxides). By using carbon as a reducing agent, decomposition of metal oxides at temperatures much lower than their typical decomposition temperatures can occur. However, a detailed fundamental understanding of such a reaction p...
متن کاملSynthesis of Boron Nitride powder by carbothermal method, using phenolic resin and carbon black and investigating the effect of additive of calcium carbonate
Effect of CaCO3 on carbothermic formation of hexagonal boron nitride (h-BN) was investigated. B2O3–C mixtures containing CaCO3 additive were reacted at 1500 for 120 min in nitrogen atmosphere. Formed phases in the reaction products were determined by powder-XRD analyses, and amounts of the constituents were determined by chemical analyses. Particle size and morphology of the formed h-BN powde...
