Ceramic body batching: Feldspar can play the role of barren raw material before firing, reduce the drying shrinkage and deformation of the body, improve drying performance and shorten drying time. During firing, it can be used as flux to reduce the firing temperature, promote the melting of quartz and kaolin, and accelerate the formation of mullite by mutual diffusion and infiltration in the liquid phase. The feldspar vitreous body generated in melting is filled between the mullite grains of the body, so that the body is compact and the void is reduced, so as to improve its mechanical strength and dielectric properties. In addition, the formation of Feldspar glass treated by PTMS magnetic separator can also improve the light transmittance of the body. The amount of feldspar in ceramic body varies with the requirements of different materials and products.

PTMS magnetic separator

Glass flux: Feldspar treated by PTMS magnetic separator is one of the main components of glass mixture. It contains high Al2O3, low iron content, and fusible than alumina, not only low melting temperature and wide melting range, mainly used to improve the content of alumina in glass batchings, reduce the melting temperature in glass production and increase the content of alkali, to reduce the amount of alkali.

what is magnetic separation in Feldspar？

The process of Feldspar melting into glass is relatively slow and the crystallization capacity is small, which can prevent the crystal precipitation in the glass formation process and damage the products. Feldspar can also be used to regulate the viscosity of glass. Generally all kinds of glass mixtures are removed by PTMS magnetic separator after iron Feldspar or albitite.
