In the changing world, the threats from riots, burglary, terror and war process have escalated and become more versatile.As a result, the transparent armors with rapidly deployable, light weight, low cost and high performance are being designed and developed competitively by many advanced countries. For providing high level protection,relatively big armour thickness is needed, which subsequently results in high armour weight. At the same time, the light transmission will decreases with increasing thickness of transparent material.Obviously,the main limiting factors for the armours are weight and thickness. .The lightweight of transparent armor mainly depends on the hard panel materials with high impact resistance.This problem of high thickness and weight of transparent armours is presently solved by developing new transparent ceramics with high hardness such as aluminium oxynitride (AlON), spinel (MgAl2O4) and sapphire (Al2O3 single crystal).However, available production technologies of these materials do not meet the criteria for requested properties(dimensions,transparency etc.) and their purchase is very expensive or even unfeasible (AlON).. Based on the application background of new transparent armor, the design techniques, preparation technology and the correlation between composition, process, structure and performance for the oxynitride glass with high ballistic energy dissipation ability（BEDA） will be investigated in order to alternative those ceramics such as sapphire and polycrystalline AlON which have high price and are difficult to prepare. The fabrication process and performance system will be established to provide the reference for the application or follow-up study of the oxynitride glass. This study has important practical value in promoting the progress of preparation science and technology for oxynitride glass and the development of new transparent armor, accelerating their practical application and meeting the demand of the national security, national defense construction and social development for high-performance transparent armor materials. Meanwhile, it is expected to obtain the correlation between composition, process, structure and performance according to the investigation results, which will provide the guidance to realize controllable preparation, performance optimization and tailoring of oxynitride glass. The theoretical value is obvious.
