WebThorium based nuclear fuel is of immense interest to India by virtue of the abundance of Thorium and relative shortage of Uranium. Thorium metal tubes were being cold drawn using copper as cladding to prevent die seizure. After cold drawing, the copper was removed by dissolution in nitric acid. Thorium does not dissolve being passivated by nitric acid.

WebThorium dioxide (ThO 2), also called thorium(IV) oxide, is a crystalline solid, often white or yellow in colour.Also known as thoria, it is produced mainly as a by-product of lanthanide and uranium production. Thorianite is the name of the mineralogical form of thorium dioxide. It is moderately rare and crystallizes in an isometric system. The melting point of … WebAug 2, 2024 · Th: The principal oxide of thorium is ThO 2, which is insoluble in acids except hot, concentrated sulfuric acid. It is not affected by fusion with the alkalis. Thorium hydroxide, when freshly precipitated, is readily soluble in acids, but after drying is more resistant. It is soluble in the alkali carbonates. Web1.
