The pyrophilite and sericite from the Mining District of Villa Union, Rioja in Argentina are well known because they are a wide area of metamorphic rocks, Precambric or Paleozoic, well distributed and communicated at aprox. 20 km from National Roads. Nowadays, two ores with different mixtures of: pyrophilite + kaolinite + quartz (white and brilliant) and other constituted by sericite (schist aspect and silk brilliant) are being exploted. In orde to define the application as raw materials for ceramic and glasses production, a full characterization of the Vichi and San Lorenzo Mines materials are being acrried out. Several ceramics, traditional and advanced, are being obtained and materials characterized for best define the application of this argentinian raw material. It has been demosntrated the obtention of ceramics based on cordierite and/or leucite by formulating ceramic bodies from this pyrophilite products.
