I. Metallic characteristics of titanium
Titanium material has high specific strength (strength to density ratio). Although the strength of titanium alloy material is slightly lower than that of the traditional material alloy steel, it has the advantage of low density, making it higher specific strength. It is widely used in the aerospace field in pursuit of light weight and high strength materials.
Titanium metal materials have excellent corrosion resistance. Corrosion is the main cause of industrial equipment failure. Although titanium element is more active, titanium alloy material can form a dense oxide film on the surface under working environment, the oxide film blocks the contact between metal and corrosive medium, so that the metal is not easy to be corroded, even because of mechanical wear will quickly self-healing or regenerated. The dielectric temperature below 315℃ titanium oxide film always maintains this property.
Titanium metal material is non-magnetic and non-toxic, and has very good biocompatibility. Titanium itself is a component of the human body and is soluble in human tissues and blood. It is basically harmless to the human body and is widely used in the medical field.
A wide range of temperatures are used. The new titanium alloy can be used at 600℃ or higher temperature for a long time. The low temperature titanium alloy represented by titanium alloys TA7 and TC4 increases its strength with the decrease of temperature, but the plastic change is little. Good ductility and toughness at -196 to -253℃, avoiding cold brittleness of metal, is the ideal material for low temperature containers, storage tanks and other equipment.
There is still room for improvement in the performance of titanium materials. Titanium alloy is a hot field of material research, and performance improvement is rapid, now the largest TC4 titanium alloy tensile strength is about 900MPa, and by the Northwest Institute of non-ferrous metals research of new titanium alloy TC21 tensile strength has reached about 1200MPa.
Ii. Products and Uses
At present, titanium products are mainly divided into titanium dioxide, titanium sponge and titanium processing materials three categories, other products also include titanium ingot, titanium powder and titanium equipment, can be widely used in aerospace, industrial production and civil production. Among them, titanium dioxide is the main component of titanium dioxide, is a kind of white pigment, mainly used in paints, plastics, ink and paper; Sponge titanium for titanium processing materials and other products of raw materials, generally light gray particles; Titanium processing material refers to titanium ingot formed by sponge titanium smelting, and then processed by forging, rolling and extrusion plastic materials, mainly divided into titanium plate, titanium bar, titanium pipe, titanium castings, etc.
Iii. Reserves
Titanium reserves on the earth are very rich, the earth's crust abundance is 0.61%, its content is higher than common copper, nickel, tin, lead, zinc, there are about 140 kinds of known minerals, but there are only more than 10 kinds of mining value. The mined titanium mineral deposits can be divided into rock deposits and placer deposits.
At the titanium end, according to the data of the United States Geological Survey, the global titanium reserves show a trend of first growth and then decline. In 2012, the global titanium ore reserves reached 650 million tons. After that, the discovered titanium reserves kept growing until reaching the peak of 880 million tons in 2018. With the substantial growth of titanium production in 2019, the global titanium reserves declined for the first time, dropping to 700 million tons in 2020.
More than 30 countries have titanium resources. But titanium is mainly found in countries such as Australia, South Africa, Canada, China and India. The types of titanium ore resources in different regions are different. Canada, China and India are mainly rock ore. Australia, the United States is mainly placer ore; South Africa is rich in rock and placer. Among them, China has the highest ilmenite reserves, reaching 230 million tons, accounting for about 32.86% of the global total reserves. Australia is the next region, reserves of 150 million tons, accounting for 21.43% of the global total reserves.The origin and use of omnipotent metal
Titanium, the element symbol Ti, is 22nd on the periodic table. In people's impression, titanium is often used in aerospace and other high-end fields, is a kind of "advanced" metal, but in fact it has been deeply into every aspect of people's lives: you may every day in the toothpaste containing titanium dioxide whitening agent brush your teeth, live in the bedroom with added titanium dioxide paint painted, with titanium alloy made of glasses frames...
Due to its good high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, high strength, low density and other characteristics, Titanium and Titanium Welded Tube is recognized as the replacement of steel, stainless steel, copper and its alloy, lead, nickel, zinc, graphite, rock and other materials ideal metal, its application range has been more and more broad. Therefore, titanium is called "omnipotent metal" in the kingdom of metal materials, and it is a "third metal", "strategic metal" and "space metal" with great development prospects after iron and aluminum.
But because titanium is difficult to separate, it can not be found in nature, its discovery and application has gone through a long process. Although the English clergyman W.Regor discovered titanium as a new metallic element in black magnetite in 1791, it wasn't officially established until 1795, when the German chemist M.H.Kraproth discovered it while studying rutile, naming it after the Greek god Titans.
After more than a century of difficult exploration, in 1910, American scientist M. A. Hunter made the first pure titanium by reducing TiCl4 with sodium. In 1940, the Luxembourg scientist W.J. roll made pure titanium by reducing TiCl4 with magnesium. Since then, magnesium reduction (also known as Klauer process) and sodium reduction (also known as Hunter process) have become industrial methods for producing titanium sponge. The United States began the industrial production of titanium in 1948 by producing 2 tons of titanium sponge by magnesium reduction process.
