Sintering characteristics, phase evolutions, microstructures, and microwave dielectric properties have been investigated for BaTi4O9 ceramics prepared by traditional low temperature sintering using CuO–TiO2 (CT) additions as aids. The of was found to evidently reduce from 1350 °C about 1100 with a very small amount 0.5 wt% CT addition. When the addition increased beyond wt%, however, it not exp...

Additive manufacturing via direct ink writing and microwave dielectric characterisation of commercially produced low sintering temperature bismuth molybdenum oxide ceramics, have been both performed for the first time, following a powder-to-product holistic approach. We demonstrated that is an excellent candidate producing substrates to be used wireless telecommunication applications operating ...

Sintering parameters of the SS316L water atomised inject ion moulded compact has been optimized for its best sintered density. The L9 (3 4 ) Taguchi orthogonal array is used in the experiment while sintering temperature, sintering time, heating rate and coofing rate was selected as factors that influenced the sintered density. The sintering environment was in the vacuum and four replications we...

This work presents the mathematic models of the basic processes from an iron ore processing plant. Based on the mathematic models, using the Matlab/Simulink platform, it was achieved the simulation of the dosing process and simulation of the sintering process. The achieved mathematic model allows the determination of the material flows in the charge at their chemical composition variation, or a...

Spark-Plasma-Sintering (SPS) compaction experiments of nanostructured titanium carbonitride powders have been performed at 1600°C and 1800°C (sintering time = 1 min). The as-received nanostructured samples have been synthesized by rapid condensation from the gas-phase (high frequency plasma). The sintering results were compared with data obtained by various conventional sintering techniques suc...
