高频红外碳硫仪测定石墨中固定碳的方法研究

Measurement of Fixed Carbon in Graphite by High-Frequency Infrared Carbon-Sulfur Instrument

石墨或石墨制品在工业上用途很广,近几年随着新能源、新材料产业的崛起,石墨产品尤其是下游深加工制品正逐渐成为国防、航天、新材料等领域不可替代的重要材料。石墨中的固定碳含量是石墨品质好坏的重要标志,固定碳是碳元素的一种结构体,属于结晶形碳,每个碳原子周边连接三个碳原子,以共价键的形式在一起相互作用,形成共价分子,固定碳具有化学性质稳定、耐高温、耐腐蚀等特点,可用作导电材料,是良好的中子减速剂等。因此各行业对石墨中固定碳含量检测方法的精密度、准确度要求也越加严格。

Graphite or graphite products are widely used in industry.In recent years,with the rise of new energy and new material industries,graphite products,especially downstream deep processing products,are gradually becoming irreplaceable and important materials in the fields of national defense,aerospace,new materials and so on.Fixed carbon content in graphite is an important sign of graphite quality,fixed carbon is a structure of carbon elements,belongs to crystalline carbon,connected to three carbon atoms,each carbon atoms in the form of covalent bond interaction,form covalent molecules,fixed carbon has very stable,high temperature resistance,corrosion resistance,used as a conductive material,is a good neutron reducer,etc.Therefore,the precision and accuracy requirements of the fixed carbon content detection method in graphite are also more and more strict.
