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.
The uses and application fields of rare earths 2024-02-07
Rare earth elements are known as "industrial vitamins" and have irreplaceable excellent magnetic, optical, and electrical properties. They play a huge role in improving product performance, increasing product variety, and improving production efficiency. Due to its importanteffect and low usage, rare earths have become an important element in improving product structure, increasing technological content, and promoting industry technological progress. They are widely used in fields such as metallurgy, military, petrochemicals, glass ceramics, agriculture, and new materials.

Application of titanium diboride in boron carbide ceramics 2024-02-05
Boron carbide, also known as black (diamond), is the third hard material after diamond and cubic boron nitride, so it has become an important member of the superhard material family. As a new type of non-oxide ceramic material, boron carbide is widely used in energy, military, nuclear and bulletproof fields because of its high melting point, high hardness, low density, good thermal stability, strong chemical corrosion resistance and neutron absorption ability. Boron carbide bulletproof material has been widely used in individual body armor, bulletproof armor, armored helicopter armor web and police, civilian special vehicles and other protection fields. At present, boron carbide bulletproof materials are mainly prepared by sintering method. In the sintering process of pure boron carbide, there are usually problems such as high sintering temperature required for densification, low density of sintered ceramics and poor fracture toughness.
