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 ...

German orthography uses "closed" compounds, concatenating nouns to form one long word. This is unlike most English compounds , which are separated using spaces or hyphens. Strictly speaking, it is made up of two words, because a hyphen at the end of a word is used to show that the word will end in the same way as the following.
