Abstract: The paper advances a new method to fast continuously determine the content of Ti and Fe with two indicators and one standard solvent‚i．e．Ti4＋ and Fe3＋ are reduced to Ti3＋ and Fe2＋ with aluminum in sulphuric and phosphoric acid with a low content of chlorhudric acid．Fe2＋ is titrated with potassium bichromate standard solvent‚with neutral rad as its indicator and manganese as catalytic agent．It achieves a satisfactory result in the analysis of high－content Ti and Fe in ceramic raw materials．

Keywords: redox process‚ceramic raw material‚titanium‚ferro
