So far, cubic boron arsenide has only been manufactured and tested on a laboratory scale, these products are not uniform, and more work is needed to determine if cubic boron arsenide can be made in a practical, economical form. But researchers say that in the near future, people may find some useful uses for the material, and its unique properties could make a significant difference. Read More »

Ceramic target can be divided into semiconductor related ceramic target, display ceramic target, magnetic recording ceramic target, optical recording ceramic target, superconducting ceramic target, giant magnetoresistance ceramic target and so on. Read More »

Titanium dioxide (TiO2)​, commonly known in industry, titanium dioxide, is also a typical semiconductor photocatalyst. Calcium carbonate (CaCO3) is a common inorganic nonmetal powder, widely used filler. The preparation of composite photocatalyst (CAT-CC) by supporting nano-tio2 with calcium carbonate particles as a carrier can improve the function of TiO2 by reducing the particle size and improving the particle dispersion.

It involves two aspects of nanomaterials, which is a hot spot. It involves matter and matter. Read More »

Cadmium was discovered in 1817 by Strohmeier, a professor of chemical medicine at the University of Gottingen in Germany. In 1990, FAO and the World Health Organization divided trace elements into three categories. The first category is essential to human body, there are 8 kinds, including iodine, iron, zinc, selenium, copper, molybdenum, chromium and cobalt. Read More »

Tungsten trioxide, chemical formula: WO3, is the oxide of tungsten (VI), which is an important intermediate of tungsten industry from tungsten ore. Yellow powder, melting point: 1472℃, relative density (water =1) 7.16, boiling point 1837℃; Insoluble in water, soluble in lye, slightly soluble in acid. It can be obtained by adding acid after eumelting tungsten ore and soda. Read More »

In the world, people generally "alumina" is divided into two categories: metallurgical grade alumina and non-metallurgical grade alumina. Non-metallurgical grade alumina is also known as multiple varieties of alumina, chemical alumina. Among them, pseudo-boehmite, boehmite, super fine aluminum hydroxide, activated alumina, calcined alumina and corundum are all belong to the chemical alumina this category. Read More »

Through chemical or physical methods to form a film on the tool surface (that is, coating process), so that the cutting tool to obtain excellent comprehensive cutting performance, so as to meet the requirements of high-speed cutting; Since the advent of hard coating tools in the early 1970s, chemical vapor deposition (CVD) technology and physical vapor deposition (PVD) technology have been developed, which has opened a new chapter in the history of improving the performance of tools.

Titanium is a chemical element, chemical symbol Ti, atomic number 22, in the periodic table of chemical elements in the fourth period, IVB group. It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine corrosion. The most common compound of titanium is titanium dioxide​, which is used to make white pigments. In the past, titanium ore was mined mainly for titanium dioxide. Read More »

Magnesium oxide was born in 1930s as a new material. In the early days of the founding of the People's Republic of China, due to the increasing demand of rubber products for magnesium oxide, a number of small workshop factories first emerged in Shanghai, but the production variety is relatively single. Until 1956 have developed light magnesium oxide and heavy magnesium oxide two specifications of varieties. Read More »

Alumina ceramic​ is a kind of a-al2o3 based crystal structure ceramic material, because of its own high melting point, high hardness, heat resistance, corrosion resistance, electrical insulation characteristics, so it can be used in more demanding conditions. Alumina ceramics, with low price and mature production process, is one of the largest and most widely used ceramic materials, mainly used in the field of cutting tools, wear-resistant parts and bioceramics.
