Borate minerals - borate minerals

Japanese: ホウ酸塩鉱物(硼酸塩鉱物) - ほうさんえんこうぶつ(英語表記)borate mineral
Borate minerals - borate minerals
A mineral containing boric acid as a chemical component. The boron atoms are coordinated by oxygen atoms in planar triangles or tetrahedrally. These structural units can also polymerize with each other to form various macroanionic groups such as (B 2 O 5 ) 4− , (B 3 O 9 ) 9− , and others. As a result, more than 100 types of borate minerals are known. The main ones are kernite (Na 2 B 4 O 6 (OH) 2 ・3H 2 O), colemanite (CaB 3 O 4 (OH) 3 ・H 2 O), ludwigite (Mg,Fe 2+ ) 2 Fe 3+ (BO 3 ), and borax.

ホウ酸を化学成分として含む鉱物。ホウ素原子は酸素原子により平面三角形,あるいは四面体的に配位される。このような構造単位はまた互いに重合して,(B2O5)4-,(B3O9)9-などのほか種々の巨大陰イオン基を形成する。そのためホウ酸塩鉱物としては100種類以上知られている。主なものはカーン石kernite Na2B4O6(OH)2・3H2O,灰ホウ石colemanite CaB3O4(OH)3・H2O,ルードウィ石ludwigite (Mg,Fe2+)2Fe3+(BO3),ホウ砂などである。
