Use dioxide in a sentence

Azurite occurs with malachite in the upper portions of deposits of copper ore, , When heated with water in a sealed tube to 150° C it yields carbon dioxide and , arsenic trioxide; titanium dioxide and silicon dioxide may be cited as exampl Strong oxidation breaks the benzene complex into such compounds, as carbon dioxide.

Silica

Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2) Silicon compounds are the most significant component of the Earth’s crust Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon The metamorphic rock, quartzite, is another source.
