Sintering – Principle and Advantages

During sintering, compacted metal powders are bonded or sintered by heating in a furnace to a temperature that is usually below the melting point of the major constituent. Sintering of powder metals is a process in which particles under pressure chemically bond to themselves in order to form a coherent shape when exposed to a high temperature. Get price

Metallurgy

Pyrometallurgical (high-temperature) methods of metal extraction and refining are extremely varied. Such processes are carried out in shaft, reverberatory, or electrical furnaces and in converters. In pyrometallurgical processes, concentration of metals and impurities takes place in various phases of the system that forms upon heating or melting of the materials being processed. Get price

To overcome these disadvantages, transition metal oxides such as CuO, ZnO and NiO are usually used as sintering aids for BCZY electrolyte densification. In principle, two approaches can be considered: Doping a metal oxide into the electrolyte lattice ( a MO + BaCe 1-x-y Zr x Y y-a O 3-δ or BaCe 1-x-y Zr x-a Y y O 3-δ ) and adding an additional amount of metal oxide into the stoichiometric Get price
