With the increase of zircon content up to 6 wt%, the strength of sintered samples increased but the apparent porosity decreased. 6 wt% is an appropriate content of zircon to possess better properties of samples, and in this case the samples have a dense microstructure and lower content of glass phase. The presence of a liquid phase resulting from zircon addition is the main reason to improve sintering of magnesia powders. %K fused magnesia %K zircon %K sintering %K densification %U http://www.doiserbia.nb.rs/img/doi/0350-820X/2009/0350-820X0901011P.pdf
