Application of DTA in preparation of glass-ceramic made by iron tailings

In view of the problem of the relatively low level use of iron tailings with low technology and low value-added, in this paper, a formula is developed to prepare the glass-ceramic product based on the full analysis on the particle size and chemical composition of iron ore tailings in Damiao, that is, a test to use differential thermal analysis to determine heat-treatment system of glass-ceramic product. The test results obtain the conclusion that DTA is exactly same as orthogonal. Therefore, it indicates that the DTA may provide a reliable guide to determine heat treatment system of glass-ceramic product.
