Learn what is aluminum?

Aluminum is the name of a chemical element in the periodic table of elements, with the symbol AI.
So what color is aluminum? This is a silvery white metal, soft and light. Aluminum is the second softest metal after gold. When exposed to air, aluminum will quickly form a thin layer of oxidation. Compared with copper or iron, aluminum has a light density, only one-third. In addition, aluminum is also the sixth most malleable metal, easy to work with.

Aluminum metal also has the advantage of high corrosion resistance, durability due to the protective oxide layer. In nature, it is difficult to find pure aluminum. Usually, this metal is found when it combines with oxygen and other elements. That’s why it’s called aluminum alloy.
Aluminum was once considered a more precious metal than gold. For some industries, aluminum is a relatively new metal as it has only been produced for over 100 years.
In particular, aluminum is in the top 10 best conductive metals after silver, copper and gold. However, aluminum is rarely used as an electrical conductor because of its high cost. Instead, people use electrical conductors made of copper more because of economic suitability.

Physical properties of aluminum

What is aluminum physical properties?

To understand more about this metal and what color aluminum is, let’s take a look at the physical properties of aluminum below.

Color and status Solid, non-magnetic, non-glossy, silvery-white with a slight blue tint.
Structure Aluminum has a cubic structure, the center of the face is stable to the melting temperature
Surface Aluminum has a highly reflective surface
Stiffness Pure aluminum is soft, when alloyed and tempered, it will be hard
Flexibility High ductility, malleable, shaped or bent
Thermal expansion The coefficient of thermal expansion of aluminum is 23.2.
Thermal conductivity Good
Corrosive Has high resistance to corrosion
Melting point, boiling point Melting point 1220 degrees F and boiling point about 4,478 degrees F

Chemical properties of aluminum and some common compounds

Chemical properties of aluminum

What is aluminum chemical?
Atomic mass of aluminum

What is aluminum structure?

Chemical structure of aluminum

  • Configuration e: [Ne] 3s23p1
  • There are 3 outermost e layers
  • Electronegativity: 1.61
  • Oxidation number: +3
  • The lattice: Face-centered cube
Aluminum is a strong reducing agent, reacts with many other elements such as water, uses acids, bases, nonmetals, and aluminum endothermic.
Reacts with non-metals: Usually forms a protective oxide film, if aluminum powder is burned, it will react strongly
Reacting with acids:
Normal Acid: Easily reduces H+ ions to H2
Oxidizing acid: Inactive with H2SO4, cold concentrated HNO3, AI strongly reacts with dilute HNO3, hot, concentrated H2SO4.
React with metal oxides – Aluminum heat reaction: AI can reduce many metal ions in oxide such as Fe2O3, Cr2O3, CuO… to free metal.
Reaction with water: Aluminum objects do not react with H20 at any temperature because of the protective oxide. Aluminum when the protective layer is removed can reduce water at room temperature, but the reaction quickly stops because of the precipitation of Al(OH)3.

Some common aluminum compounds

  • Aluminum sulfate: A chemical compound of aluminum, the formula is Al2(SO4)3. Characteristic is that it can be dissolved in water, mainly used as a precipitant in drinking water filters and wastewater treatment plants.
  • Aluminum sulfide: Composed of two elements AI and sulfur, the formula is Al2S3. This compound is colorless, has an interesting structure, and exists in many different forms.
  • Aluminum Oxide: A protective layer for aluminum metal from corrosion. Formula is Al2O3, commonly used in ceramic materials, moisture resistant
  • Aluminum hydroxide: The chemical formula is Al(OH)3, found in nature as the mineral Gibbsite. This compound is used in the production of other aluminum compounds.
  • Aluminum Nitride: An inorganic chemical compound, the main components are Al and N. The chemical formula is AlN. This is a semiconductor material, which is used for intensive ultraviolet optoelectronics.
  • Aluminum chloride: A binary salt, formed by Al and with the formula AlCl3. This compound is produced and consumed in the field of AI metal production, chemical industry.
