Potash Feldspar an overview ScienceDirect Topics

The flaggy potash feldspar content is approximately 25%–30%, and shows different degrees of kaolinitization and sericitization. The granular quartz content is approximately 20%–25%. The column’s hornblende content is approximately 3%–5%, also showing chloritization.

The Mineralography of the Feldspars Part II

As our knowledge of the feldspar group, outside of crystallog-raphy, is to a very large degree confined to the plagioclase series, about one-half of the present paper is devoted to the potash-soda series. This system includes orthoclase, microcline, albite, "bar-bierite," anorthoclase, perthite, etc.

THE MELTING RELATIONS OF POTASH FELDSPAR,

ABSTRACT. P.C.E. values of ternary mixtures of potash feldspar, soda feldspar, and flint were determined and results shown on a solid phase diagram. No eutectics were developed with either of the binary series of feldspar and flint. The soda feldspar‐flint mixtures were more refractory than were those of the potash feldspar series.

Feldspar an overview ScienceDirect Topics

The feldspar fuses when it melts, forming a glass matrix. The feldspars are mixtures of potassium alumino-silicate (K 2 O Al 2 O 3 6SiO 2) and sodium alumino-silicate, also known as albite (Na 2 O Al 2 O 3 6SiO 2). Feldspars are naturally occurring substances, so the ratio between the potash (K 2 O) and the soda (Na 2 O) will vary somewhat. This affects the properties of the feldspar, in that the soda tends to lower the fusion temperature and the potash
