Abstract:

The iron-rich schorl was took as the research objects in this paper and the high temperature phases transformation of the schorl were discussed. The preparation and infrared properties of the schorl glaze, of what is the melting temperature lower than 800°Cwere studied and also the law of improving water quality by the schorl glaze were tested and analyzed. The results showed that the schorl can be decomposed into mullite and iron oxide when the temperature higher than 800°C; the far-infrared emissivity of the glaze prepared by the schorl mixed with more than 40wt% low temperature frit reached 0.885; the property of schorl glaze is weaker than the material supported on porous ceramics modified by schorl in improving water quality (pH value).
