天然鳞片石墨制备柔性石墨化学组成变化及耐蚀性研究

Study on Ash Content Variation of Flexible Graphite Material Made from Nature Flake Graphite and it's Corrosion-Resistance Properties

本文采用体积比为１：１的浓硫酸与浪硝酸对中碳天然鳞片石墨进行浸泡以制造柔性石墨。探索了浸泡时间对石墨化学组成变化的影响，同时对含有一定灰份（主要为二氧化硅）的柔性石墨的耐蚀性进行初步测试。

The high ash content nature flake graphite is used as raw materials to produce flexiblegraphite by mixture acid dipping, the sulfuric acid and nitric acid is at the ratio of 1:1(volume ). Therelationship between dipping periods and ash content is investigated, and corrosion-resistance Properties ofthe flexible graphite table with some ash content are tested.
