Brief overview
Ulexite is hydrated sodium calcium borate hydroxide represented as NaCaB5O6(OH)6·5H2O. It is predominately found in California and Nevada in the US, in Chile and Kazaksthan. It is often referred to as TV rock, for its silky white rounded crystalline appearance. Ulexite is also found in a vein-like bedding habit composed of closely packed fibrous crystals. Ulexite crystals contain three structural groups, isolated pentaborate polyanions, calcium coordinated polyhedra, and sodium coordinated octahedra that are joined together and cross-linked by hydrogen bonding.
