Iron boride is like a really cool toy that is made up of two different things: iron and boron. Iron is a metal that is strong and can be made into all sorts of things like tools and machines. Boron is a type of element that is not a metal but is still really interesting.
When we mix the iron and boron together, we get something called iron boride. It's like mixing blue and yellow paint together to get green. Iron boride is super strong and can resist things like heat and wear and tear. That means it can be used in all sorts of places where things need to be tough and last a long time.
Scientists have figured out how to make iron boride in different shapes and sizes so it can be used in lots of different things. It's like making little Lego bricks out of iron boride so they can be put together to make big and strong things like planes and cars.
So, in summary, iron boride is a special material made of iron and boron that is super strong and used to make tough things that need to last a long time.
