Borate mineral

The Borate Minerals are

Many borate minerals, such as borax, colemanite, and ulexite, are salts: soft, readily soluble, and found in evaporite contexts. However, some, such as boracite, are hard and resistant to weathering, more similar to the silicates.

There are over 100 different borate minerals.^[2][3] Borate minerals include:

• Kernite Na₂B₄O₆(OH)₂·3H₂O
• Borax Na₂B₄O₅(OH)₄·8H₂O
• Ulexite NaCaB₅O₆(OH)₆·5H₂O
• Colemanite CaB₃O₄(OH)₃·H₂O
• Boracite Mg₃B₇O₁₃Cl
• Painite CaZrAl₉O₁₅(BO₃)
