  Preparation technology and application field of pyrolytic graphite crucible

  2023-04-25

  Chemical vapor deposition (CVD) is a process that uses gaseous substances to produce chemical reactions and transport reactions on solids and produce solid deposits. It roughly includes three steps: 1. Form volatile substances; 2. transfer the above substance to the deposition area; 3.A chemical reaction occurs on the solid and produces a solid substance. The most basic chemical vapor deposition r

  Square graphite crucible and maintenance tips

  2023-03-14

  Square graphite crucibles are processed from square graphite blocks. Graphite block can be formed by molding process, vibration forming process or isostatic pressing. Graphite crucible has excellent performance, and has a small coefficient of thermal expansion during high temperature use, and has certain strain resistance to rapid cooling and rapid heating, so it is widely used in the smelting of
