[求助] 有谁知道陶瓷基复合材料的相对密度是什么

有谁知道陶瓷基复合材料的相对密度(relative density)是什么?
我制备SiO2/SiO2复合材料的方法是silicasol-infiltration-sintering方法。
参考文献: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
编辑给我的意见是我制备的复合材料的相对密度(relative density)是多少。我不知道我制备的这个材料的relative density是什么意思,谁能帮我解答一下啊,万分感谢!最好也给我发几篇有相关   复合材料相对密度的文献,多谢![ Last edited by 李冬冬1989 on 2011-10-4 at 21:20 ]

relative density is the ratio, in 100% form, from the density of your sample to the real density of SiO2 ceramic(you can check it in Wiki or else). for example 90%.

谢谢你的回答。这个问题纠结我很久了,我还不是特别明白,  我能加你QQ详聊吗???我懂了的话  肯定给您加上金币,万分感谢!

谢谢你的回答,写中文是不是更好点呢?具体我还不是很懂,能详细点嘛??如果有几篇文献专门写相对密度的就更好了,能发给我吗?

关键是这个百分比是怎么确定的?我不大懂相对密度中的 “相对”的意思

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.

按照您的意思是:我制得的复合材料的密度/SiO2的密度=相对密度??可是百度上写SiO2的密度是2.2 ~2.66,这具体数值怎么取呢???     这样算出来的相对密度只有0.77左右的啊!

李冬冬1989(金币+50): Thank you. You are knowledgeable, kind and beautiful ! 2011-10-12 10:11:48
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.
