In this paper,the properties and utilities of TiB2ceramic were introduced. When different sintering additives were used,the influence on sintering character of TiB2ceramic was emphasized. The different sintering techniques were compared. In this paper,the properties of TiSi2were expounded. The paper analyzed the evidence that TiSi2as sintering additive can improve the sintering and antioxidant properties of TiB2ceramic. In the paper,some urgent problems that TiSi2can enhance the sintering and antioxidant properties were put forward. The viewpoint of paper provides a new road about enhancing sintering properties of TiB2ceramic and the viewpoint has theoretical significance and application of value.
