Titanium diboride can be prepared by a variety of methods, including but not limited to direct synthesis, boron thermal method, molten electrolysis, assisted immersion metal method, carbon thermal method, self-propagating high temperature synthesis (SHS), vapor deposition method and sol-gel method. The specific introduction is as follows: 12

Direct synthesis method: titanium powder and high-purity boron powder are directly combined at high temperature to form titanium diboride. This method is expensive and usually only used in laboratories.



Self-propagating high-temperature synthesis (SHS): This method uses magnesium powder as a reducing agent, initiates the reaction through an igniter, and uses the heat released by the reaction to complete the synthesis. The titanium diboride produced by this method has small and uniform particle size, but there are technical difficulties.
Vapor deposition method and sol-gel method: These two methods use the gas phase and sol state as the starting state, respectively, to prepare titanium diboride through chemical reactions and gelation processes. These two methods are generally suitable for laboratory-scale preparation.
