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...
متن کاملTow-Step Synthesis of Aluminum Oxynitride (AlON) via Carbothermal and Nitridation Route
The aim of this research was to study synthesize gamma aluminum oxynitride powder with cubic spinel structure. In order to carry out this process, carbothermal reduction and nitridation of α-alumina as starting powder was used. This process was carried out in two steps, that in the first step at 1550˚C, a portion of α-alumina was reacted with carbon and aluminum nitride (AlN) was formed, then i...
متن کاملFe(NO3)3-assisted large-scale synthesis of Si3N4 nanobelts from quartz and graphite by carbothermal reduction–nitridation and their photoluminescence properties
The large-scale synthesis of Si3N4 nanobelts from quartz and graphite on a graphite-felt substrate was successfully achieved by catalyst-assisted carbothermal reduction-nitridation. The phase composition, morphology, and microstructure of Si3N4 nanobelts were investigated by X-ray diffraction, Fourier transform infrared spectroscopy, field-emission scanning electron microscopy, energy-dispersiv...
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...
متن کاملSynthesis of Ti4O7 Nanoparticles by Carbothermal Reduction Using Microwave Rapid Heating
The polymer electrolyte fuel cell (PEFC) is an attractive power generation method from the perspective of environmental protection. Carbon is usually used as a catalyst support in PEFC, but it is oxidized under high electrical potential conditions. Ti4O7 is expected as a new catalyst support because of its high electrical conductivity and chemical resistivity. Though Ti4O7 as a catalyst support...
