ulexite

[′ü·lek‚sīt] (mineralogy) NaCaB₅O₉·8H₂O A white mineral that crystallizes in the triclinic system and forms rounded reniform masses of extremely fine acicular crystals. Also known as cotton ball.

Ulexite

(named after the German chemist G. L. Ulex [1811-83]), a mineral of the subclass of hydrous borates, NaCa[B₅0₉]-8H₂0. Ulexite crystallizes in the monoclinic system. It forms white compact masses of fine fibers or radiating aggre gates. It has a hardness of 1 on Mohs’ scale and a density of 1,650 kg/m³. Ulexite occurs as a supergene mineral in lake deposits and is a substitution product in argillaceous gypsum-bearing ores in salt domes. It is an ore of boron. Ulexite deposits are found at Inder (USSR) and in Nevada (USA).
