Abstract
BERZELIUS1 reported that boric acid precipitates white flocculent thorium borate when added to a solution of a salt of that element; the precipitate is insoluble in an excess of boric acid. Karl2 discussed the composition of the amorphous white precipitate obtained by treating an aqueous solution of thorium nitrate with a hot solution of borax and showed that the composition corresponded with thorium orthoborate, Th3 (BO3)4. Guertler3 could not prepare thorium borate by fusing thoria with boric oxide on account of the very sparing solubility of the thoria. A search of the literature revealed that no work is on record on the formation of the hydrosol and the hydrogel of thorium borate. An attempt has now been successfully made in this laboratory to prepare thorium borate hydrosol and hydrogel.
