The raw material for preparing metal titanium is mainly rutile, which contains more than 96% TiO2. Countries that lack rutile ore, such as the Soviet Union, use "high-titanium slag" made of ilmenite, which contains about 90% TiO2. Due to the rising price of natural rutile and the decreasing reserves, all countries tend to use ilmenite to make titanium-rich materials, namely high-titanium slag and artificial rutile. Titanium was discovered in 1791, and the first pure titanium was made in 1910, more than a hundred years later. The reason is that titanium is very active at high temperature, and it is easy to combine with oxygen, nitrogen, carbon and other elements, and very harsh conditions are required to extract pure titanium.

Content distribution

By the end of 1995, the world's rutile (including anatase) reserves and reserve base were 33.3 million tons and 164.4 million tons respectively, and the total resources were about 230 million tons (TiO2 content, the same below), mainly concentrated in South Africa, India, Sri Lanka, Australia. The world's ilmenite (TiO2) reserves and reserve base are 274.3 million tons and 435.3 million tons respectively, with a total resource of about 1 billion tons; mainly concentrated in South Africa, Norway, Australia, Canada and India.

Application of Titanium Alloy

Titanium is corrosion-resistant, so it is often used in the chemical industry. In the past, stainless steel was used for the components in chemical reactors that contained hot nitric acid. Stainless steel is also afraid of the strong corrosive agent - hot nitric acid. Every six months, this kind of parts must be replaced. Making these parts out of titanium, while a little more expensive than stainless steel parts, can last five years and is far more cost-effective to calculate.

Titanium compounds

The oxide of titanium is titanium dioxide, which is the highest valence oxide of titanium. Natural TiO2 is rutile, pure TiO2 is snow-white powder and is the best white pigment, commonly known as titanium dioxide, white when cold and light yellow when hot. In the past, the main purpose of mining titanium ore was to obtain titanium dioxide. Titanium dioxide has strong adhesion and is not easy to chemically change. It is always snow-white and is an excellent white paint. It has high refractive index, strong coloring, high hiding power and stable chemical properties. Other white coatings, such as zinc white ZnO and lead white 2PbCO3·Pb(OH)2, etc., do not have these excellent properties of titanium white. Especially valuable is that titanium dioxide is non-toxic. It has a high melting point and is used to make refractory glass, glaze, enamel, clay, and high-temperature laboratory utensils.

chemical reaction

Titanium is a chemically very active metal, but its melting point is as high as 1668°C. Titanium can also react with many elements and compounds at higher temperatures. According to its different reactions with titanium, it can be divided into the following four categories: The first category: halogen and oxygen group elements and titanium to form covalent bonds and ionic bond compounds;

physical properties

Titanium alloys have good low temperature resistance. Titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo are represented by low-temperature titanium alloys, and their strength decreases with temperature. The increase, but the plastic change is not large. It maintains good ductility and toughness at a low temperature of -196-253 °C, and avoids the cold brittleness of metals. It is an ideal material for low-temperature containers, storage tanks and other equipment.

Domestic development history

China's titanium industry started in the 1950s. In 1954, Beijing Nonferrous Metals Research Institute began to study the preparation process of titanium sponge. In 1956, China included titanium as a strategic metal in its 12-year development plan. The first sponge titanium production workshop, and China's first titanium plate and strip processing material production test workshop was established in Shenyang Nonferrous Metal Processing Plant. Baoji titanium processing equipment, technical level and production capacity all rank first in the country, with production capacity accounting for about 60% of China's total, market share accounting for 85% of China's domestic titanium processing material market, accounting for 22% of the world's output, responsible for 90% of China's The production task of high-end titanium products above % is known as China Titanium Valley.

Development history abroad

In 1940, Luxembourg scientist W.J.Kroll obtained pure titanium by reducing TiCl4 with magnesium. Since then, the magnesium reduction method (also known as the Krauer method) and the sodium reduction method (also known as the Hunter method) have become the industrial methods for producing sponge titanium. In 1948, the United States produced 2 tons of titanium sponge by the magnesium reduction method, and the industrial production of titanium began.
