Processing of High-Quartz Porcelain Tile with Large Yellow Sand

Abstract:

In this study, the yellow sand waste with enormous reserves in the Inner Mongolia Tengger desert was taken as the main raw material mixed with the same regional clays for the infrared functional low-temperature porcelained tile. The mineral composition and granule feature of Tengri yellow sand as well as the micro-structure and infrared property of the fired body were discussed by the means of various testing such as the grain fineness distribution analysis, the XRD diffraction analysis, the SEM scanning electron microscope analysis, the coefficient of thermal expansion measure and the infrared performance detection. The results revealed that the natural mineral could be replaced by the yellow sand waste in large for preparing the environmental protection functional porcelained ceramics with favorable properties. The flexural strength of porcelained tiles sintered at 1140°C~1160°Ckeeps from 40 to 55Mpa when the high addition of yellow sand varies 75wt% to 90wt%. And the body is composed of high quartz as the main phase and little wollastonite phase which meets with the thermal shock resistant standard of the present architectural material .
