Elemental Uses Of Titanium

Titanium is strong, with pure titanium having a tensile strength of up to 180 kg/mm². Some steel strength is higher than titanium alloy, but the specific strength of titanium alloy (tensile strength and density ratio) is more than the quality steel. Titanium alloy has good heat-resistant strength, low temperature toughness and fracture toughness, so more used as aircraft engine parts and rockets, missile structure. Titanium alloy can also be used as fuel and oxidizer storage tanks and high-pressure containers. Now there are titanium alloys used in the manufacture of automatic rifles, mortar plates and recoilless cannon launch tubes. In the petroleum industry, mainly for a variety of containers, reactors, heat exchangers, distillation towers, pipelines, pumps and valves. Titanium can be used as electrodes and power station condensers and environmental pollution control devices. Titanium-nickel shape memory alloy has been widely used in instrumentation. In the medical treatment, titanium can be used as artificial bones and various appliances. Titanium is also a deoxidizer for steelmaking and a component of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints. Titanium carbide, titanium carbide (hydrogen) is a new type of hard alloy material. Titanium nitride color close to gold, widely used in decoration.

Titanium and titanium alloys are widely used in the aviation industry, known as "space metal"; in addition, there is an increasingly wide range of applications in the shipbuilding industry, the chemical industry, the manufacture of mechanical components, telecommunications equipment, cemented carbide and other aspects.

In addition, because titanium alloy also has good compatibility with the human body, so titanium alloy can also be used as artificial bone.
Titanium corrosion resistance zirconium is an application in the atomic energy industry and used as corrosion-resistant chemical materials at high temperatures and pressures, but its activity in solution is second only to sodium.
So, adding a solution of active zirconium nitrate to a solution of titanium hydroxide reveals that titanium rejects zirconium nitrate (as shown in the figure).

As you can see, there is a clear delamination in the figure, with zirconium nitrate on the top and titanium hydroxide on the bottom.

We know that titanium hydroxide is less dense than zirconium nitrate, but it still maintains the obvious layering and keeps zirconium nitrate in the upper layer, which proves the corrosion resistance of titanium.

According to the experiment, titanium will not be corroded when it is put into the seabed for 20~50 years.
