FELDSPAR   Feldspar are aluminosilicates with varying amounts of K, Na and Ca in a solid solution series; the main commercial feldspars lie between the sodium(albite) and potash (Microcline) rich end members, and the sodium end of the sodium-calcium series (Oligoclase).   Properties & uses   In glassmaking feldspar is used a source of Al2O3, Na2O, and/or K2), and SiO2 [borosilicate glass; soda-lime glass; fiberglass; TV tube glass]. The alumina enhances the workability of molten glass, increases the resistance of glass to chemical corrosion, improves the hardness and durability, and inhibits devitrification, In ceramics, feldspar acts as a flux to form a glassy phase in bodies [vitreous and semi vitreous china; wall & floor tile; sanitary ware; electrical porcelain; frits, glazes & enamels]. Feldspar is also used as a mild abrasive [scouring powders] and welding rod coating; With properties such as sub-angular particle shape, H 6-6.5, G.E. brightness 0f 82-92%, non-photo reactivity, and low free silica content, fine-ground feldspar is a useful filler.   Grades we offer   We offer grades of sodium and potassium bases feldspar for the ceramic industry. For further details on grades available and offers please contact us.   Quality & specifications:   Soda spar is preferred in glass and potash spar in ceramics. Glass grade feldspar: 4-6% K2O, 5-7% Na2O, 19% Al2O3 with a max 0.08% Fe2O3. Pottery grade feldspar: 5-14% K2O, with max 0.07% Fe2O3.

Fused silica as an industrial raw material is used to make various refractory shapes such as crucibles, trays, shrouds, and rollers for many high-temperature thermal processes including steelmaking, investment casting, and glass manufacture.Refractory shapes made from fused silica have excellent thermal shock resistance and are chemically inert to most elements and compounds, including virtually all acids, regardless of concentration, except hydrofluoric acid, which is very reactive even in fairly low concentrations.Translucent fused-silica tubes are commonly used to sheathe electric elements in room heaters, industrial furnaces, and other similar applications.Quartz glassware is occasionally used in chemistry laboratories when standard borosilicate glass cannot withstand high temperatures; it is more commonly found as a very basic element, such as a tube in a furnace, or as a flask, the elements in direct exposure to the heat.

Glass Type: Fused Quartz / Silica  Fused quartz is a result of melting crystalline silica in the form of stone, sand or rock. It is sometimes used in the same applications as fused silica. The main differences are that fused quartz has a much lower OH content and fused silica transmits better in the UV. Both are highly pure, have high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient.   Thermal Properties Thermal Coefficient of Expansion (0/300°C): 5.5 X 10 -7/°C Annealing Point 1213.83°C / 2216.9 °F Softening Point 1683°C / 3061 °F Strain Point 1122°C / 2051.6 °F Mechanical Properties Density 2.21 g/cm3 Knoop Hardness >600 Kg/mm2 Young's Modulus 10.5 X 106 PSI (70 Gpa) Poisson's Ratio .17 Electrical Properties Dielectric Constant 3.75 @ 20°C, 1 MHz Resistivity 7 X 107 ohm * cm (350°C) Dielectric Strength 1270 volts/mil
