摘要
以紫砂土为主要原料,加入纳米紫砂和纳米石英短纤,采用塑性成型并煅烧。通过XRD物相分析,采用急冷—强度法表征试样的抗热震性能,研究纳米材料添加量对紫砂陶器强度及抗热震性能的影响。结果表明:随着纳米材料的加入,紫砂陶器抗折强度与抗热震性能都有所提高。当纳米材料加入量为1.19%时,两者性能均达到最大,抗折强度达68.7 MPa,抗热震强度达26.0 MPa。
Using Zisha clay, nan-Zisha, Nano quartz fiber as the raw materials, Zisha were prepared by plastic molding and sintered. The effects of nano-materials contents on flexural strength and thermal shock resistance of Zisha samples were investigated by water cooling-strength method and XRD. It was found that flexural strength and thermal shock resistance of Zisha samples increased with the con tents of nano-materials. The flexural strength was 68.7 MPa and thermal shock strength was 26.0 MPa reaching to the maximum when 1.19% nanomaterial was used.
