Thus, five basic structural units are usually distinguished in borates according to the coordination number of the boron atoms and to the number of BOs and NBOs belonging to the given boron atom: [B.sub.3][0.sub.3] symmetric triangle ([empty set] is BO), [[B[[empty set].sub.4]].sup.-] borate tetrahedron, B[[empty set].sub.2][O.sup.-] metaborate triangle, B[empty set][O.sub.2.sup.2-] pyroborate unit, and B[O.sub.3.sup.3-] orthoborate anion.
Zinc borate (2ZnO x 3[B.sub.2][O.sub.3] x 3[H.sub.2]O) was observed to react with MgO to form of a different crystalline phase, magnesium orthoborate, with crystalline ZnO as a by-product of the reaction.
