Determination of the trace iron 、 nickel 、 titanium and chromium in pure molybdenum trioxide product by emission spectroscopy 用发射光谱技术测定高纯氧化钼产品中铁、镍、钛和铬的含量
Production of ferrous powder by oxidative roast of copperas, a byproduct of titanium pigment was introduced, and optimum process for the transformation of sulfur to sulfur trioxide was studied. Preparation of ( NH_4)_2SO_4 and Red Fe_2O_3 from Side Product of Making TiO_2 Powder 介绍了以硫酸法钛白粉副产物绿矾为原料,氧化焙烧生产铁红粉,并研究了氧化反应中硫转化为三氧化硫的适宜工艺条件。钛白粉副产物硫酸亚铁生产硫酸铵和氧化铁红的研究
