An unstable monoclinic form, isomorphous with rubidium and ammonium dichromates, has been obtained adnhxed with the triclinic variety, by concentrating, after filtration from aluminium hydroxide, a mixture of potassium chromate and aluminium sulphate, and allowing the solution to crystallise. It may also be obtained in yellowish brown, doubly refracting monoelinic plates by crystallisation of a mixture of solutions of potassium diehromate and potassium thiocyanate. ... [Pg.61]

L. Grandeau prepared rubidium chromate, Rb2Cr04, by neutralizing a soln. of the dichromate with rubidium carbonate, and by melting chromic oxide with rubidium nitrate, or with rubidium carbonate in air. The spontaneous evaporation of the aq. soln. furnishes first a crop of crystals of the dichromate, and then the... [Pg.137]
