Layered ceramic material - Ti3SiC2 2024-08-24
In recent years, materials scientists have synthesized a new class of type 312 ceramic materials, whose general formula is M3XZ2, in which M is one or several transition metal elements (such as Ti, V, etc.), X is one or several main group elements, and many III and IV main group elements (such as Al, Ge, Si, etc.). Z is one or several non-metallic elements (such as C, N, B, etc.), 312-sex ternary compounds currently studied are mainly Ti3SiC2, Ti3AlC2, Ti3GeC2. They have the same crystal structure and belong to the P63/mmc space group. A typical example of this class of compounds is Ti3SiC2. This paper briefly introduces the Ti3SiC2 ceramic material.

Review on the application of vanadium 2024-06-22
In the iron and steel metallurgy industry, vanadium is an important alloying element additive, which can effectively increase the strength, toughness and ductility of steel, accounting for 85% of the amount of vanadium. In the aerospace industry, adding a small amount of vanadium to titanium alloys can play the role of strengthener and stabilizer, and the amount is about 10%. In addition, vanadium is mainly used as a catalyst and colorant in the chemical industry, with the amount of about 5%. In other industries, vanadium is also used to produce vanadium batteries, vanadium nanomaterials, vanadium films and so on.

The outbreak of new energy and the acceleration of "vanadium batteries" 2024-05-07
On new energy batteries, a battle surrounding the periodic table has begun. From the previous lithium "nouveau riche" to the current vanadium. Vanadium batteries have once again caught people's attention, with the leading Panzhihua Iron and Steel Vanadium Titanium doubling its stock price in nearly 19 trading days. And the sector index has risen by nearly 4%. In the vanadium market, it is basically "whoever obtains vanadium gains the world".
Cerium boride 2024-04-20
Cerium boride is an inorganic compound with the chemical formula CeB6, which is composed of cerium and boron elements. Cerium boride has various applications, especially in the fields of electronics and materials science. Its relative atomic mass is also an important parameter that plays an important role in research and application. Cerium hexaboride (CeB6) is a cathode material with extremely high electron emissivity due to its lower work function. It is more resistant to carbon pollution and has a longer lifespan than lanthanum boride cathodes. It is widely used in fields such as electron microscopy, microwave tubes, electron beam etching, electron beam welding, X-ray tubes, and free electron lasers. Cerium hexaboride crystals have been successfully applied in desktop scanning electron microscopes, becoming excellent and stable filament materials.
Silver paste for photovoltaic auxiliary materials 2024-04-13
Photovoltaic silver paste is mainly composed of high-purity silver powder, glass oxides, and organic carriers, and is mainly used to estimate the current generated by the front and back electrodes of photovoltaic cells and silicon-based photovoltaics.
Vanadium 2024-03-02
In 1801, Mexican mineralogist A.M. DelRio discovered a new element while studying brown lead ore. Its chemical properties were similar to chromium and uranium, and its salts turned red when heated in acid. Therefore, it was named "erythronium", meaning "red element", but later it was mistaken for alkaline lead chromate. In 1831, Swedish chemist N.G. Sefstrom discovered a new element while smelting pig iron, which had beautiful and colorful compounds. He named it Vanadium after the Swedish goddess Vanadius. Vanadium was used as a coloring agent in 1860. In 1867, British chemist H.E. Roscoe reduced VCl with hydrogen to obtain the first pure silver gray metallic vanadium powder. In 1869, France studied the use of vanadium as an alloying agent in the production of armor steel plates. In 1896, vanadium was used as a special steel additive in Europe. Vanadium was used as a catalyst in 1870. Vanadium containing alloy steel was used as a raw material in the automotive industry around 1905. In 1927, J.W. Marden and M.N. Rich in the United States produced industrial metal vanadium using an electric furnace calcium thermal reduction method.
