The Microstructure and Corrosion Resistant of Corbon-Bonded Forsterito-zirconia Materials

以锆英砂和电熔镁砂为原料，合成ZrO2增韧的镁橄榄石材料，进而加入鳞片状石墨，得到Mg2SiO4(-ZrO2)-C复合材料。用扫描电镜、X射线衍射仪、差热、红外光谱等手段研究了该材料的显微结构和矿物组成。表明该材料具有优异的高温强度、抗侵蚀性和热震稳定性，是一种新型耐火材料。

The forsterite-zirconia material have been produced from the zircon and magnesia, adding graphite, to produce a Mg2SiOZrO2-C. The microstructure and Mineral composition have been studied by means of microscope, SFM,X-ray, diffractometer and DTA. It is a nice refractories that the brick have densed structure, thermal stability, good thermal conductivity and wear-resistance, and good resistance to the corrosion by iron-oxide slay.
