有誰知道陶瓷基復合材料的相對密度(relative density)是什么? 我制備SiO2/SiO2復合材料的方法是silicasol-infiltration-sintering方法。 參考文獻:Mechanical properties and microstructure of 2.5D (shallow straight-joint) quartz fibers-reinforced silica composites by silicasol-infiltration-sintering;Ceramics International, In Press, Corrected Proof, Available online 10 August 2011 Yong Liu, Jianxun Zhu, Zhaofeng Chen, Yun Jiang, Chengdong Li, Binbin Li, Long Lin, Tianru Guan, Zhaohai Chen 編輯給我的意見是我制備的復合材料的相對密度(relative density)是多少。我不知道我制備的這個材料的relative density是什么意思,誰能幫我解答一下啊,萬分感謝!最好也給我發(fā)幾篇有相關 復合材料相對密度的文獻,多謝![ Last edited by 李冬冬1989 on 2011-10-4 at 21:20 ] |

first, test your samples density D1, like Archimedes methods. second, try to find the real density of SiO2 D2, internite at last, the relative density=D1/D2*100%. I think its easy. you can conect with me by Email: yumo821@sohu.com |

I think that should be right, 77%. One suggestion, as a material science student, you should learn how to use google, wiki, databases and articles to find data,I mean the real density of SiO2. Baidu is not professinal. Good luck. |
