Spectral pure graphite rod must be of high purity, especially in the qualitative analysis of trace elements, extremely trace impurities are not allowed to exist.
Generally speaking, impurities in graphite materials used for inspection in spectral analysis mainly include Al, B, Ca, Cu, Fe, Mg, Si, Ti, V etc. in addition, K, Mn, Cr, Ni, etc. may also exist. Due to the improvement and application of high purification research and purification technology in related industries, almost no impurities can be detected now, and the industrial manufacture of high purity graphite rod for spectral analysis has been realized.
Super high purity
Good lubricity, high temperature resistance, oxidation resistance, strong acid and alkali resistance, strong thermal shock resistance, good electrical conductivity, high mechanical strength.
Widely used in spectrum analysis electrode, crucible, electrodes for smelting quartz
Widely used in the fields of metallurgy, machinery, electronics, chemical, light industry, aerospace and refractory industries
