Copper chromite

Development of Copper Chromite Catalyst for Furfural Hydrogenation

改性铜铬加氢催化剂的开发

But , by and large , hexavalent chromium content is far less than any national and international standards ; this proves copper chromite black pigment to be a kind of non-toxic and environmental protection pigment .

总的来说，铜铬黑中六价铬含量远远低于国际及国家标准，说明铜铬黑是环保无毒的。

Research has shown that both ions have relatively big influence on the lattice parameters of the copper chromite black pigment samples . With the increase amount of doped ions , phase transition was happened on the pigment samples .

研究表明：这两种离子对铜铬黑的晶格影响较大，随着掺杂量的增加可以导致样品发生相转变，由四方相转向立方相。

In this paper , a composite inorganic environmental protection pigment copper chromite black were prepared by homogeneous precipitation method , co-precipitation method and Sol-Gel method . And on the basis of Sol-Gel method , ions doped samples were studied to show the influence on the copper chromite black pigments .

本文采用均匀沉淀法、共沉淀法和溶胶-凝胶法合成了具有优异性能的环保型复合无机颜料铜铬黑，并在溶胶-凝胶法的基础上，研究了离子的掺杂对颜料性能的影响。
