A uranate is a ternary oxide involving the element uranium in one of the oxidation states 4, 5 or 6. A typical chemical formula is M x U y O z , where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. [ 1 ]
Clarkeite is a uranium oxide mineral with the chemical formula (Na,Ca,Pb) 2 (UO 2) 2 (O,OH) 3 or (Na,Ca,Pb)(UO 2)O(OH)·0-1H 2 O.. Its color varies from dark brown to reddish orange. Clarkeite forms by oxidation and replacement of uraninite late during pegmatite crystallizat

Thesaurus Linguae Latinae. A modern english thesaurus. A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms ...
WordNet is a lexical database of semantic relations between words that links words into semantic relations including synonyms, hyponyms, and meronyms. The synonyms are grouped into synsets with short definitions and usage examples. It can thus be seen as a combination and extension of a dictionary and thesaurus.
Sodium uranate may be obtained in the amorphous form by heating together urano-uranic oxide and sodium chlorate; or by heating sodium uranyl acetate or carbonate. The crystalline form is produced by adding the green oxide in small quantities to fused sodium chloride, or by dissolving the amorphous form in fused sodium chloride, and allowing ...
The compound can be prepared by treating uranium trioxide]] with acetic acid: . UO 3 + 2 CH 3 COOH + H 2 O → UO 2 (CH 3 COO) 2 ·2H 2 O. The acetate ligands of uranyl acetate can be replaced to give a variety of uranyl complexes. [6]
