Lithium oxide facts for kids
Lithium oxide is a chemical compound that you might hear about in science class! Its chemical formula is Li2O. This means it's made up of two lithium atoms and one oxygen atom. It's a special type of compound that contains lithium and oxide ions, which are tiny charged particles.

What is Lithium Oxide Like?
Lithium oxide is a white solid. Think of it like a white powder. It's known as a strong base. In chemistry, a base is the opposite of an acid. When lithium oxide dissolves in water, it becomes very corrosive, meaning it can damage or wear away other materials. When it mixes with water, it forms another compound called lithium hydroxide.
Lithium oxide also reacts with acids to create different types of lithium salts. If it reacts with carbon dioxide (the gas we breathe out), it forms lithium carbonate. Lithium carbonate is much less corrosive than lithium oxide. A cool fact is that if you put lithium oxide in a flame, it makes the flame turn a bright red color!
How is Lithium Oxide Made?
One way to make lithium oxide is by burning lithium metal in the air. When lithium burns, it reacts with the oxygen in the air to form lithium oxide. This process can also create a small amount of lithium nitride. Another way to get lithium oxide is by heating up lithium peroxide, which is another lithium compound.
What is Lithium Oxide Used For?
Lithium oxide has several interesting uses:
- Glazing Ceramics: It's often used as a flux when making ceramics. A flux helps materials melt and flow more easily, which is important for creating smooth, shiny glazes on pottery and tiles.
- Scientific Research: Scientists use lithium oxide in their labs for various experiments and studies because of its unique chemical properties.
- Batteries: It could also be used in lithium-ion batteries, which power many of our electronic devices like phones and laptops.
Is Lithium Oxide Safe?
It's important to know that lithium oxide is a very corrosive substance. This means it can be harmful if it touches your skin or if you breathe it in. When it mixes with water, it creates lithium hydroxide, which is also very strong and can cause burns. Because it's a strong base (also called an alkali), it's considered toxic and should always be handled with great care by trained professionals.
