Abstract

New examples of anhydrous and hydrous borates are presented to illustrate a recently published method for calculating the ratio of triangularly to tetrahedrally coordinated B atoms in advance from the borate formula [Z. Kristallogr. 217 (2002) 179]. Assuming that the bonding model upon which this method is based proves right, all borate phases obtained from one borate by a thermal treatment should have the same triangle-to-tetrahedron ratio. This includes all the crystallized and amorphous phases in a dehydration sequence of a hydrous borate and all the high-temperature modifications of an anhydrous borate. Selected examples for the thermal behavior of borates are discussed in view of the expected constancy of the triangle-to-tetrahedron ratio.
