Abstract:A new raw-material for ceramics, with its good performance of quick calcine at the lower temperatures, has attracted much attention from the research institutions and factories since it was introduced into the calcine (making) of glazed bricks. This paper, taking the Laoguanzhuang diopside deposit as an example, discusses its geologic conditions, the evaluation method and the technology of its development and application so as to bring into full play the advantages of this mineral resources.
