An example that is certainly almost pure advanced ceramics is corundum, which in its finest form is often a precious stone- sapphire or ruby-and in less beautiful forms is situated in such abrasives as emery. Alumina is also called aluminum oxide. In the form of a white powder, it can be employed in producing aluminum. Aluminum can be a metal of your silvery gray color.

It is an element, meaning it isn't made by combining other substances. Aluminum is advantageous in many ways. It really is lighter than most other metals. It never rusts. Being soft, it can be easily hammered, rolled or pressed into any desired shape. Aluminum is lighter than copper which is as good for conducting electricity. This makes it useful as electric wire and areas of electric machines. It can be rolled into sheets thinner than tissue paper, called foil, that are accustomed to wrap stuff that will be spoiled by dirt or water. The thing is that aluminum daily. Pans and pots are constructed with it. Its softness can make it good for toothpaste tubes. As it does not rust and is also so light, it is employed for making airplanes, railroad cars, truck bodies, boats, and bridges. Its silvery color can make it attractive in paints, signs, and a lot of other items.
