GreenSpar is derived from the igneous rock Anorthosite, which is composed of 90% Plagioclase Feldspar, formed in a low quartz environment, resulting in a dense and consistent formation, with less than 10% being other minerals. Purity levels increase with the removal of iron bearing micas during processing which results in a monomineralic Anorthite.

2018-8-11 · Feldspars - all about the plagioclases and K-feldspars. Feldspars are alumosilicates of alcalic metals and form a significant portion of many volcanic and metamorphic rocks. As such, they are one of the most important mineral groups on the Earths surface: some estimate that they form between 50-60 % of the Earths crust.
Albite and anorthite feldspar-based ceramics were synthetized and sintered in the range 1000−1070 °C and 1300−1500 °C, respectively. They observed that a slow cooling (0.5 °C/min) during sintering improved dielectric properties regarding fast cooling. .
