brief introduction is presented for the methods of corn bustion synthesizing TiN including gas-solid,liquid-solid, and solid-solid methods.The effective factors of all these methods are also-discussed in detail. The results show that solid-solid methos is insensitive to nitrogen pressure and diluent,it is one of the simplest technology in the three methods.However,the most typical and common method is gas-solid cormbustion synthesizing method,due to the avilable of nitrogen resoursce.
