Morphology
thoriate = thorium (transparent) = thori + ate
Formed by adding the verb-forming suffix '-ate' to the element name 'thorium' (via the combining stem 'thori-'), so knowing 'thorium' makes the meaning clear.
Etymology
Thoriate comes from the element thorium, which was named after the Norse god Thor, and the ending -ate is a common chemical verb meaning 'to treat with', as in carbonate or nitrate. So to thoriate something is to treat or coat it with thorium (often as thorium oxide), which explains why engineers use it to increase emission.
