Main Difference
Aluminum gets defined as the type of metal that has a light silver or gray outlook and becomes a chemical element with the atomic number 13 and symbol of Al. Alumina gets defined as the type of substance that has a white outlook and robust base and becomes a major part of many rocks and minerals along with corundum and sapphire.

Aluminum
Aluminum gets defined as the type of metal that has a light silver or gray outlook and becomes a chemical element with the atomic number 13 and symbol of Al. It had many uses and became standard as an industrial item because of its properties that help it to work in extreme conditions. Aluminum is a shiny white metal, the 13th component in the periodic table. One astonishing actuality about aluminum is that it’s the most boundless metal on Earth, making up over 8% of the Earth’s center mass. It’s additionally the third most basic compound component on our planet after oxygen and silicon. In the meantime, since it effortlessly ties with different elements, pure aluminum does not happen in nature. It is the reason that individuals found out about it moderately as of late. Formally aluminum delivered without precedent for 1824, and it took people an additional fifty years to figure out how to create it on a universal scale. The most widely recognized type of aluminum found in nature is aluminum sulfates. These are minerals that consolidate two sulphuric acids: one given an antacid metal and one in the light of metal from the third gathering of the occasional table, fundamentally aluminum. Aluminum sulfates are utilized right up ’til today to clean water, for cooking, in prescription, in cosmetology, in the synthetic business, and different divisions. Coincidentally, aluminum got its name from aluminum sulfates which in Latin were called alumen. Bauxite is a mud mineral including various alterations of aluminum hydroxide blended with iron, silicon, titanium, sulfur, gallium, chromium, vanadium oxides, and sulphuric calcium, iron and magnesium carbonates.
Alumina
Alumina gets defined as the type of substance that has a white outlook and robust base and becomes a major part of many rocks and minerals along with corundum and sapphire. Beside silicates, aluminas are the richest mineral of the earth outside. In this manner, it is imperative for concoction specialists to know some science about aluminas since they are found and utilized as a part of such a variety of better places and advances. Moreover, aluminum particles frequently supplant silicon particles in silicates shaping aluminosilicates, which gets talked about on the following page. From the dialog on this page, you will be acquainted with different types of alumina, their structures, and properties so that when you experience them, you can connect their resources with their concoction personalities arrangements and structures. The most widely recognized mineral is bauxite, which is aluminum oxide, Al2O3, blended with oxides of silicon, iron, and different components and shifting little rates of dirt and various silicates. Physically, bauxite can be as hard as a shake or as delicate as mud, and its shading might be red, white, buff, pink, yellow or any blend of these. The photo demonstrates the mining of bauxite at Gove in Australia Bauxite is the result of extreme substance weathering of aluminum-rich rocks. It additionally fills in as the crude material for a broad scope of cutting edge clay items and as a dynamic operator in concoction handling.
Key Differences
- Aluminum gets defined as the type of metal that has a light silver or gray outlook and becomes a chemical element with the atomic number 13 and symbol of Al.
- Alumina gets defined as the type of substance that has a white outlook and robust base and becomes a major part of many rocks and minerals along with corundum and sapphire.
- Aluminum exists on its own in natural form in the atmosphere, on the other hand, alumina, also known as aluminum oxide exists only when mixed with oxygen.
- One critical difference between these two comes when we talk about the electrical properties. Aluminum becomes one of the best electrical conductors, on the other hand, alumina becomes one of the best electrical insulators.
- Aluminum becomes highly reactive and acts with hydrogen and oxygen along with others to form different substances. On the other hand, alumina does not react well with others and therefore serves as a protective layer over the original material.
- Aluminum reacts with oxygen to form aluminum oxide, also called alumina. On the other hand, alumina decomposes to form aluminum.
- Aluminum has extensive use in industry whereas the use of alumina becomes enough.
