• Why can silicon carbide and boron carbide ceramics be bulletproof

  In everyone's impression, ceramics is fragile, but after modern technology processing, ceramics "suddenly changed", has become a hard, high strength new material, since the 21st century, bullet-proof ceramics developed rapidly, there are many kinds, including alumina, silicon carbide​, boron carbide, silicon nitride, titanium boride, etc. Among them, alumina ceramics (Al2O3), silicon carbide ceramics (SiC), boron carbide ceramics (B4C) are widely used.

• 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".

• Pressure working properties of magnesium alloys

  The pressure machinability of metallic materials depends on two relatively independent factors of the material: the machinability related to stress state (SOS) and the machinability inherent in the material itself. The machinability of SOS depends on the geometrical relationship of the deformation zone, and the workpiece is in three-dimensional stress state in the deformation zone.
