  • About author:Hilmar Schulze-Bergkamen is Head of R&D China/East Asia at RHI Magnesita located in Dalian, P. R. China. He obtained his PhD in Germany, based on a thesis about sol-gel manufactured thin PZT films and joined the Tokyo Institute of Technology as a postdoctoral researcher. Since then, he has taken up various roles as QA and R&D Manager within the glass and refractory industry.


Since early 2020 RHI Magnesita has been running a fully integrated dolomite plant in Chizhou, Anhui Province, P. R. China. The current operation consists of a world-class dolomite mine including a state-of-the art sinter plant equipped with rotary kiln plus a plant where shaped and unshaped doloma products are being manufactured. As raw dolomite has been a technically usable carbonate rock for decades the article describes the way from raw dolomite stone to doloma production.

Key words: dolomite, doloma refractories, stainless steel
