Effect of Ta on the oxidation resistance of a cast Nickel-base die material with low Cr and high W content Qing Li 1, a , Chengbo Xiao 1 , Jinxia Song 1, Dinggang Wang 1 and Yafang Han 1 1 National Key Laboratory of Advanced High-Temperature Structural Materials, Beijing Institute of Aeronautical Materials�BIAM�, Beijing 100095, P.R.
Molybdenum alloys, such as TZM alloys are used as die materials, which are able to work at temperatures up to 1700� [3].
A more economical way is using nickel-base superalloy or Ni3Al-base alloys as die materials working in air, which was reported in Russia and Japan [4,5].

Study Formation Process of Cement Clinker Minerals by Using Calcium Carbide Slag as Raw Material Wang Yali1,a, Dong Shijie1,b, Liu Linlin1,c ,Cui Suping1,d and Xu Haibo2,e 1College of Materials Science and Engineering, Beijing University of Technology, Beijing, China 2Equipment Department, Army Aviation Institute, Beijing, China a wangyali1978@bjut.edu.cn , b dongshijie_rain@emails.bjut.edu.cn, c lllydcg@emails.bjut.edu.cn , d cuisuping@bjut.edu.cn Keywords: Industrial waste, Calcium carbide slag, Limestone, Calcium containing raw material.
But, there are many differences in decomposition temperatures between the calcium containing raw materials.
Compared with limestone materials, calcium carbide slag has a higher content of CaO, less loss on ignition, a lower alkali content, higher sulfur and chlorine contents.
There are many differences in decomposition temperatures between the two raw materials.

Applying ion chromatography to analyze the decomposition products, it is proved that nano-titanium dioxide can decompose NOx, HC, CO and other harmful gases into nitrate and carbonate.Then, an excellent concrete protection materials- anticorrosive of silane solvent is selected as dispersion solvent, and a certain amount of titanium dioxide is dispersed evenly in the solvent to make the coating material with photocatalytic performance, the brushing method and decomposition effect of the coating material are discussed.
Compared with other photocatalytic materials ZnO, CdS, WO3, Fe2O3, TiO2 owns good chemical stability, reactivity and other characteristics [7].
