... While a number of beryllium-containing minerals have been identified, only beryl (3BeO-Al 2 O 3 -6SiO 2 ) and bertrandite (4BeO-2SiO 2 -H 2 O) have been commercially significant to date. Beryl occurs in isolated pockets in pegmatites and, with the possible exception of operations in the Soviet Union...

... to avoid incipient melting. Sodium peroxide, the most common sintering agent, may be applied to many minerals and ores, including feldspar, quartz, scheelite, beryl, and rutile. If the sample contains little sulfur, and the temperature remains below 500 °C (930 °F), a platinum crucible may be used. A 1:2...

When the silica rings degenerate into chains, the structures are referred to as pyroxenes if they contain single-ring chains and amphiboles if they contain double-ring chains ( Fig. 8 ). Compounds of this type include diopside, CaMg...
