Method of determining technological properties of feldspars based on volume and shape changes at gradual heating of a feldspar starting material sample and kit for making the same

摘要

This invention relates to determining the technological properties feldspar based on its volume and shape changes of the gradual heating of the feldspar raw material using hot microscope and kit for performing this method. Volume and shape changes of the sample feldspar are recorded in the form of hot microscopic curves and / or appearance of the sample profile with gradually heating. From the measured dip microscopic curves and profile appearance of the sample can be accurately determined fundamental characteristic temperature points Raw particular point early shrink (a), point early sintering (b), the ending point of sintering (c), point early melting (d) and the beginning of the spills ( e) and / or intervals between them, and point hemisphere. Based on the determined values ​​and the waveform can infer the composition of the sample and its suitability or unsuitability for use in the glass and ceramics industries.
