• Rare earth materials | rare earth luminescent material

  Since ancient times, humans have preferred light and feared darkness, dreaming of controlling light at will, and now we have developed many practical luminous materials. In these luminescent materials, rare earth elements​ play a big role, far more than other elements. Due to the unique electron layer structure of rare earth elements, rare earth compounds show many excellent optical, electric and magnetic functions

• Application of silicon carbide in heat conduction materials

  Silicon carbide (SiC) has a broad application prospect in semiconductor, nuclear energy, national defense and space technology due to its good wear resistance, high temperature mechanical properties, oxidation resistance and other properties. With the development of society and the progress of science and technology, electronic equipment and instruments tend to be more and more precise, miniaturization and high performance, and put forward new requirements for heat conduction and heat dissipation.

• Properties and applications of magnesium oxide

  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.

• The influence of nano-alumina on the properties of alumina ceramics

  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.

• Silicon nitride thin film - the most important dielectric material in the manufacture of integrated circuits

  Silicon nitride​ (Si3N4) thin films are widely used as dielectric materials. As amorphous insulating material, dielectric properties of silicon nitride film is better than that of silica membranes, have to the movable ions blocking ability strong, compact structure, small pinhole density, good chemical stability, high dielectric constant, etc. In the field of integrated circuit manufacturing is widely used for surface passivation coating, insulation, impurity diffusion etching mask mask, as well as the surface of the semiconductor encapsulation and so on.

• What metal powder materials are used for 3D printing

  Metal 3D printing​ is a 3D printing technology that uses metal powder to directly print metal parts, also known as metal Powder sintering (SLM). In addition to good plasticity, 3D printed metal powders must also meet the requirements of small particle size, narrow particle size distribution, high sphericity, good fluidity and high bulk density. The metal powders used in most 3D printers include stainless steel, aluminum alloy, cobalt-chromium alloy, copper alloy, titanium alloy and nickel alloy.

• Why use iridium instead of wider chrome for the pen nib

  In order to increase the wear resistance of the nib, the small particles of osmium and iridium​ raw ore in the free state of nature were welded on the nib in the early stage of foreign countries. But the limitation and output and quality, with the development of metallurgical technology, osmium, iridium and other precious metals to join other metals into metal particles, because the alloy contains iridium, so called "iridium grain".
