Introduction Elemental beryllium is a steel gray appearing alkaline earth metal with properties like brittleness and high rigidity being the lightest among metals. The majority of beryllium is found in minerals and soils rather than in its elemental form. Beryllium is found in about 30 different mineral species like different compounds including aluminium e.g. Beryl (beryllium aluminium silicate).
Evaluation of brittleness index (BI) is a fundamental principle hydraulic fracturing design. A wide variety BI calculations often baffle field engineers. The traditional value comparison may also not make the best BI. Moreover, it mixed up with fracability in applications, thus causing concerns. We, therefore, redefine as pressure under certain rock mechanical (mainly brittleness), geological a...
