What gem mineral is an oxide of aluminum?
Ruby and sapphire are both gem varieties of the mineral corundum, an aluminum oxide.
An aluminum oxide mineral called bauxite.
No, Aluminum ore is usually the mineral bauxite, which I believe is aluminum oxide.
No, it is an aluminum oxide. Silicates contain silicon oxide.
Aluminium/aluminum occurs naturally as the mineral called bauxite. This is an oxide of aluminium/aluminum.
Aluminum oxide is the scientific name. As a mineral it is called corundum.
Bauxite contains aluminum oxide, from which aluminum metal is refined.
Hematite is the main ore of iron, a reddish black mineral consisting of ferric oxide
One is oxidized aluminum and the other is oxidized iron. Iron oxide is magnetic. Aluminum oxide is not. Most of the clear semi precious gems like rubies and emeralds are made from aluminum oxide. Iron oxide is in hematite the black, opaque mineral.
Diamond is pure carbon Also, Sapphire is Aluminum Oxide. (Analogous to how Iron Oxide is rust!)
A variety of corundum, an aluminum oxide. Al2O3
Yes, ruby is the red gem variety of a mineral called corundum, an aluminum oxide. Interestingly enough, sapphire is also nothing but a trade name for corundum, and it's not just blue, it's found in a wide range of colors.
Yes, it is a silicate mineral. "Feldspar is the mineral name given to a group of minerals distinguished by the presence of aluminum (Al) and the silica ion (SiO4) in their chemistry. This group includes aluminum silicates of soda (sodium oxide), potassium (potassium oxide), or lime (calcium oxide). Feldspar is the single most abundant mineral group on Earth."

When exposed to air the surface of a piece of aluminum will oxidize and form a coating of aluminum oxide, known in its mineral form as corundum. Aluminum oxide is one of the hardest substances on Earth and so protects the aluminum from further oxidation. It is possible to get aluminum to corrode. Mercury will prevent the oxide from forming a protective coating.
Aluminum oxide, known in geology as the mineral corundum.
Bauxite is a Metallic Resource, its a Solid Mineral and derived from Aluminum. Bauxite is also called Aluminum Oxide.
Alumina is a compound of aluminum and oxygen. It is better known as aluminum oxide or, if it is in mineral form, corundum.
Sapphire is made of the mineral corundum (aluminum oxide) with impurities to give it color.
Rubies are made of the mineral corundum an contain impurities that give them a reddish color. Corundum is the mineral name for aluminum oxide.
Yes, it can. Aluminum oxide, saphires or rubys are all the same mineral. Just with minor elemental differences.
what is gem mineral
Bauxite is not on the periodic table as it is a mineral compound containing mainly aluminum oxide.
Sapphire is a form of aluminum oxide - alpha Al2O3.
Sapphire comes from the corundum mineral family, which is an aluminum oxide (Al2O3). Corundum consists of pure aluminum oxide, it also contains trace amounts of other elements such as iron, titanium and chromium.
Sapphire is the most precious and valuable blue gemstone. It is a very desirable gemstone due to its excellent color, hardness, durability, and luster. In the gem trade, Sapphire without any color prefix refers to the blue variety of the mineral corundum. Source: http://www.minerals.net/gemstone/sapphire_gemstone.aspx
No. A gem mineral is a mineral that can be considered a gemstone if it of a high enough quality. Garnet, for example, is a gem mineral, but many garnets are not gem-quality.
No, Al2O3 is aluminum oxide, it occurs naturally as the mineral corundum. Silica is silicon dioxide or SiO2, it occurs naturally as the mineral quartz.
Yes, it is an incredibly rare gem. It can be green, blue, or white in color and is a mineral that can be classified as a subcategory of jade. It contains sodium, aluminum, and iron and can be categorized under the pyroxene group.
No, aluminum oxide is not metallic. But aluminum is.
What is the definition of aluminum oxide Aluminum Oxide refers in particular to Fused Aluminum Oxide or Fused Alumina herehttpwwwiabrasivecomproductsabrasive-grains?
The definition of aluminum oxide is various forms of aluminum oxide. This only occurred naturally as corundum.
A diamond is both a mineral and a gem.
Yes, like the mineral Quartz is also a gem.
No. Ruby is the red variety of the mineral corundum or aluminum oxide (Al2O3). Beryl is a beryllium aluminum sillicate (Be3Al2Si3O18) and forms gemstones such as emerald and aquamarine.
Rubies are an element.These are compounds of a crystallized mineral called corundum that consists mostly of aluminum oxide (Al2O3).
Sapphire is a gemstone variety of the mineral corundum, an aluminum oxide (α-Al2O3), when it is a color other than red, in which case the gem would instead be a ruby.

Aluminum oxide = Al2O3
No No Aluminum Oxide Al_2(O_2)_3 has Al and O which are elements. Aluminum Oxide is a compound
Ruby is a Generation lll game. Diamond is a Generation IV game. They are set in different areas. Ruby is set in the Hoenn region, and Diamond, in the Sinnoh. Outside the world of Pokémon, ruby and diamond are gem stones. Diamond is a carbon crystal. Ruby is the mineral corundum (aluminum oxide) that has a red color because of the presence of chromium. Gem-quality corundum without chromium is called a saphire
Rubies (and sapphires also) are compounds of a crystallized mineral called corundum that consists mostly of aluminum oxide (Al2O3).
Rubies are a variety of corundum, the mineral name for aluminum oxide, Al2O3. The red color comes from trace amounts of chromium.
Aluminum and oxygen form aluminum oxide. Aluminum and iodine form aluminum iodide.
In general, for a mineral to be a gem it should be hard, durable, and colorful.
Aluminum oxide is Al2O3
Aluminum oxide has the formula Al2O3
No, Aluminum oxide is a pure substance.
Aluminum oxide is Al2O3 and when heated it is still Al2O3, so heating aluminum oxide does nothing to it.
No. Diamond is a crystalline form of the element carbon. Ruby is a red variety of the mineral corundum, the mineral form of aluminum oxide. Diamond is notably harder than corundum.
A mineral is generally considered to be of gem quality if it is hard, durable, and colorful.
Yes! a gem is a highly prized mineral which is prized for it beauty.
Topaz. [toh-paz] -noun; a mineral, a fluosilicate of aluminum, usually occouring in prismatic orthorhombic crystals of various colors, and used as a gem.
Aluminum oxide is an ionic compound.
