Chemical Powder Liquid quotation Basic Info Composition: potassium, sodium, calcium, barium, etc Product color: meat red, gray, white brown. Yukuan potassic feldspar powder is white, gray and light yellow, and anorthite is white or light gray Application Uses of potassic feldspar powder or albite: mainly used in ceramic industry, glass industry and enamel industry. Feldspar containing rare elements such as rubidium and cesium can be used as mineral raw materials for extracting these elements. Feldspar with beautiful color can be used as decorative stone and inferior gem. Description Potassic feldspar powder has the advantages of low melting point, long melting interval, high melting viscosity and small fluidity. Widely used in ceramic material, electrode and other industrial sectors. Titanium oxide of feldspar & Lt;0.02%, burning vector 0.54, hardness fluctuates between 6-6.5, brittle, has high compressive strength, has strong chemical stability to acid, uses; Manufacturing flat glass, alkali glass, glassware, ceramic oil, high - voltage porcelain, etc. Soda Feldspar is one of the forms of feldspar, also known as Na-Feldspar. Soda Feldspar is generally a clean white mineral that sources sodium, alumina and silica along with some potassium and calcium. No actual materials have the ideal formula shown here, they all have some K2O and small amounts of other contaminants. Manufacturers refer to their materials as 'soda' if Na2O predominates over K2O (often manufacturers refer to their materials at soda-potash feldspars (or vice versa) if neither of the oxides predominates). Nepheline Syenite is often used in similar circumstances, however it has a higher alumina content (often the lower alumina content of soda feldspar provides more room in glaze recipes for alumina sourcing ball clay or kaolin to help suspend the slurry). In ceramic bodies, soda feldspar is main fluxing agent. The flux is defined as that portion of the body which develops glass phase in the ceramic industry. This is provided mostly by feldspar.The amount of flux in a ceramic body should be only in such a proportion as to develop the desired amount of vitrification. If excess of flux is added, the fired body becomes very glassy and consequently, brittle. Basically, the two properties which make feldspars useful for downstream industries are their alkali and alumina content. Feldspars play an important role as fluxing agents in ceramics and glass applications, and also are used as functional fillers in the paint, plastic, rubber and adhesive industries.
