In this paper, the research process of the fire - proof calcium silicate board trial - produced with theindustrial tailings - felspar powder is reported.
The compositions of phyllosilicate and iron oxides for several main types of soils and their corresponding iron-manganese nodules were studied by the means of XRD.
This paper reports a method of specimen preparation for the quick measurement of the thickness of powderof phyllosilicate mineral-casting mounts,and its application in the test of the products.
For sinter with 25% and 50% MAC fines the iron oxides mainly consisted of hematite and magnetite, the bonding phase were mainly dicalcium silicate, glassiness, and a few amount of calcium ferrite.
