• Very "magnesium" is very strong, crack plastic poor!

  As the lightest metal structure material, magnesium​ has broad application prospects in aerospace, automotive, high-speed rail, electronic products and medical and other fields. However, compared with traditional metal materials, magnesium has poor plasticity, difficult deformation processing of profiles and parts, and high process cost. This severely restricts the wide application of magnesium as a structural material.

• Crucible material selection for OLED evaporation

  In the manufacturing process of OLED, "evaporation" is the essence part but also the difficulty. It refers to a coating technology in which the materials to be evaporated are heated by resistance or electron beam, and the atoms are vaporized by crucible in the vacuum chamber to reach and adhere to the substrate surface under high vacuum condition.

• The difference between alumina, pseudo-boehmite and boehmite

  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.
