Titanium is a light, strong, corrosion-resistant transition metal that is commonly used in aerospace applications. It is extracted from ilmenite and rutile ores using the Kroll or Hunter processes. Titanium can be alloyed with other metals like aluminum and vanadium to produce high-strength, lightweight alloys used in aircraft, spacecraft, industrial equipment, and more. It has the highest strength-to-weight ratio of any metal and excellent corrosion resistance, making it well-suited for applications where strength and durability are important. Titanium reserves are abundant, though extraction is difficult.

1. titanium properties and uses
Titanium is a chemical element, chemical symbol Ti, atomic number 22,
is a silver-white transition metal, which is characterized by light weight,
high strength, with metallic luster, also has good corrosion resistance
(including sea water, And chlorine). Because of its stable chemical
properties, good resistance to high temperature, low temperature
resistance, strong acid, anti-alkali, and high strength, low density,
reputation as "space metal" . Titanium was discovered in 1791 by William
Gregor in Cornwall, England, and named by the Titan of Greek
mythology by Martin Heinrich Klaproth.

2. Titanium is considered to be a rare metal, due to its dispersion in nature
and difficult to extract. But its relative abundance ranks tenth among all
the elements. Titanium ore mainly ilmenite and rutile, widely distributed
in the crust and lithosphere. Titanium is also present in almost all
creatures, rocks, water bodies and soils. Extraction of titanium from the
main ore requires the use of the Crow method or the Hunt method.
Titanium is the most common compound, and titanium dioxide can be
used to make white pigments. Other compounds include titanium
tetrachloride (TiCl) (as a catalyst and for the manufacture of smoke or
air) and titanium trichloride (TiCl) (for the production of polypropylene).

3. Titanium can be alloyed with other elements such as iron,aluminum,
vanadium or molybdenum to produce high-strength light alloys,which are
widely used in all aspects, including aerospace (jet engines, missiles and
spacecraft), military, industrial processes Chemical and petroleum
products, desalination and papermaking),automobiles, agricultural
food,medicine (prostheses,orthopedic and dental instruments and fillers),
sporting goods,jewelery and cell phones.
Titanium The two most useful properties are corrosion resistance, and the
highest strength-to-weight ratio in metals . In the non-alloy state, the
strength of titanium with some steel, but still light 45% [8]. There are two
kinds of allotropes ,and five natural isotopes, from Ti to Ti, where the
highest abundance is Ti(73.8%) .The chemical properties and physical
properties of titanium are similar to those of zirconium,since the valence
electrons of the two are the same and are of the same family in the
periodic table.
In the

titanium
reserves
after iron,
aluminum,
magnesium, ranking fourth. As the titanium has a high melting point,
small specific gravity, high strength, good toughness, anti-fatigue,
corrosion resistance, low thermal conductivity, high and low temperature
tolerance performance, Century fifties began to be recognized, was
applied to aviation, aerospace and other high-tech fields. With the
continuous promotion of chemical, oil, electricity, desalination,
construction, daily necessities and other industries, titanium has been
increasingly valued, known as the "modern metal" and "strategic metal"
is to improve the level of national defense equipment indispensable Of
the important strategic materials.
