Highlights The effect of borax content on the properties of MKPC under high temperatures was tested. Magnesia reacted with borax to generate Mg3B2O6 at 800 °C. The addition of borax can contribute to the sintering of MKPC. More borax content led to lower porosity, denser structure and higher compressive strength. Lower borax content led to excellent dimensional stability.
Abstract This paper studied the effect of borax content on the physic-mechanical properties and microstructure of MKPC at high temperatures. Borax affected the performance of MKPC by changing phase composition and structure at high temperatures. Borax can react with magnesia to form Mg3B2O6 at around 800 °C. The porosity of MKPC reduced at temperatures of higher than 900 °C, mainly due to the melting of Mg3B2O6. As borax content increased from 3% to 15%, MKPC showed a denser structure and higher strength at 1100 °C. Excellent dimensional stability of MKPC at high temperatures can be obtained at low borax content.
