Albite (Plagioclase Feldspar NaAlSi₃O₈)
Categories:	Ceramic; Oxide; Aluminum Oxide; Silicon Oxide
Material Notes:	Two cleavage directions. Weathering end products: Kaolinite, illite. Occurrence: Igneous and metamorphic rocks. All feldspars are good indicators of the rock freshness. Albite is a limiting composition for the plagioclase feldspar series (Na_xCa_1-x)(Al_2-xSi_2+x)O₈ (x = 0.9 to 1 for Albite) Property values are typical of naturally occurring Albite (Feldspar NaAlSi₃O₈). Actual property values will vary from sample to sample.
