Recycling waste materials have attracted considerable attention owing to the increased interest in depressing the negative impact on the environment. The present work investigates the effect of increasing the granite sludge-waste materials from granite manufacture-on the physical, mechanical and electrical properties of magnesia ceramics. The temperature-induced forming (TIF) method is used to shape magnesia-granite sludge ceramics. The sintered ceramics are characterized by XRD and SEM, in addition to measuring the bulk density, apparent porosity, linear shrinkage, microhardness, and electrical resistivity. Sintering of magnesia-granite bodies resulted in the formation of periclase-forsterite ceramics. The XRD results show that the forsterite phase increases reaching 78% at 40 wt% granite. The increase in granite sludge from 10 to 40 wt% increases the bulk density from 1.86 to 2.69 g/cm³ and the apparent porosity decreases from 40 to 15%, respectively. Microhardness is improved by increasing the granite sludge wt% reaching 7.9 GPa. The microstructure of the formed periclase-forsterite is versatile with a rhombohedral structure for periclase and a flower structure for forsterite. The forsterite phase is formed by the diffusion of granite sludge into the formed periclase.

由于人们越来越有兴趣减少对环境的负面影响，因此回收废料引起了极大的关注。本工作研究增加花岗岩生产过程中产生的花岗岩污泥废物对氧化镁陶瓷的物理，机械和电学性能的影响。温度诱导成形（TIF）方法用于使镁质花岗岩石污泥陶瓷成形。除了测量堆密度，表观孔隙率，线性收缩率，显微硬度和电阻率之外，烧结陶瓷还通过XRD和SEM进行表征。氧化镁-花岗岩体的烧结导致形成长钙镁橄榄石陶瓷。XRD结果表明，在40 wt％的花岗岩上，镁橄榄石相的增加达到78％。^{如图3所示}，表观孔隙率分别从40％降低到15％。通过增加花岗岩污泥的重量百分比达到7.9 GPa，可以改善显微硬度。形成的镁橄榄石-镁橄榄石的微观结构是多功能的，菱镁石的菱面体结构为镁橄榄石的花形结构。镁橄榄石相是通过花岗岩污泥扩散到形成的镁长石中形成的。
