Its material flow process is that, mining resources flow in the production process as raw materials, and then products made from raw materials access to trading market.
After purchased and used by consumers, waste materials changed from products are released to the environment, while those generated in the production are directly discharged to the environment[4].
This industry converts waste materials generated during production and utilization into reutilizing resources and products, including two processes, firstly, wastes are converted into renewable resources, then renewable resources are processed into products[5].

In order to investigate the effects of TiN content on Al2O3/TiN ceramic material (ATN), the ATN ceramic materials were prepared of TiN content in 30%, 40%, 50%, 60% in the condition of hot press sintering.
It is indicated that the TiN content has important effect on microstructure and mechanical properties of ATN ceramic materials.
ATN ceramic materials have simple manufacturing process, better performance and lower cost, but their performances are general.
