Related Research on Hard Material Molybdenum Diboride

Synthesis method of molybdenum diboride：

The main synthesis methods of MoB2 are high-temperature synthesis and chemical vapour deposition. The high-temperature synthesis method directly reacts with molybdenum and boron to produce MoB2 at high temperatures. The advantage of this method is that the process is simple but requires higher temperature and longer reaction time. Chemical vapour deposition (CVD) is a method of deposition and growth of MoB2 film on a substrate by controlling the composition of reaction gas and reaction conditions. The advantage of this method is that high-quality MoB2 film can be prepared at a lower temperature.

In addition to the above two methods, there is a sol-gel method, electrochemical deposition method, ion implantation method and other methods to prepare MoB2. For example, the sol-gel method can prepare MoB2 powder with high purity and dispersion, but the process is more complicated. MoB2 films with specific morphology and size can be prepared by electrochemical deposition, but the preparation conditions are strict.
