Abstract

Lithium octoborate is prepared by melting 74 parts by weight of lithium carbonate or 48 parts by weight of lithium hydroxide together with 500 parts by weight of boric acid in a graphite crucible or in a free flame at 650 DEG C. The melt is allowed to cool slowly, the resulting solid mass disintegrated to a grain size of less than 3 mm., any soluble portions of the mass extracted with water, and the residue dried and graded. Lithium metaborate is prepared by dissolving 62 parts by weight of boric acid in 300 parts by weight of hot water and mixing the resulting solution with a solution of 42 parts by weight of the hydrate of lithium hydroxide (LiOH.H2O) in 400 parts by weight of water. The resulting solution is concentrated, whereby the octohydrate of lithium metaborate (LiBO2.8H2O) is precipitated in the form of coarse crystals which are filtered off, dried, ground and graded.
