Sodium peroxide is a strongly oxidizing alkali flux. Most of the minerals in silicate rocks can be rapidly decomposed by sinter with Na2 O 2 at a temperature of 480 ± 20 °C, and a sample-to-Na 2 O 2 ratio of 1:4 is usually used ( Rafter, 1950; Seelye and Rafter, 1950 ). Lower temperatures (below the melting point of Na 2 O 2) result in less ...
· Plagioclase minerals are hard, non-metallic minerals that exhibit two cleavage directions that meet at nearly right angles. The name 'plagioclase' refers to this cleavage pattern, coming from the Greek words for 'oblique' (plagios) and 'to break' (klasis).Apart from pegmatites, the plagioclase minerals seldom occur as well-defined isolated crystals, but instead occur as …
