In principle, the strength of glass structure decreases with increasing Na content.
In glass structure, magnesium (Mg) and aluminium (Al) are network modifiers that can improve the structural strength and the weathering resistance of glass.
The amount of sodium in glass effect on the strength of glass structure.
The weathering resistant depends on the chemical composition focusing on alkaline/alkaline earth (Na2O, K2O, CaO, MgO) and glass structure modifier (Al2O3, ZrO2) [10].

A novel active Ni-Ce-Al-mixed oxide catalysts for oxidative dehydrogenation of propane Ruheng A a, Jiang Wangb and Bao Zhaorigetu c College of Chemistry and Environmental Science, Inner Mongolia Key Laboratory of Green Catalysis, Inner Mongolia Normal University, Hohhot 010022, China aangel8888462@yahoo.com.cn, bwangjiang@imnu.edu.cn, czrgt@imnu.edu.cn Keywords: Hydrotalcite-derived oxides, Oxidative dehydrogenation, Propane Abstract.
Ce can replace Al in a wide range of Ce/Al ratios to form Ni-Ce-Al-LDH with the unique layered structure of hydrotalcite.
The Ni-Ce-Al mixed oxide catalysts exhibit superior catalytic activity in oxidative dehydrogenation of propane and the excellent activities were attributed to mesoporous structure and the suppression of coke deposition.
The initial hydrotalcite was calcined at 600°C, where the layered structure has been destroyed.
The main contribution of the mesoporous struture in the catalytic reaction consists in the transfer of reactant streams, and thus the pore structure of the prepared catalyst is conducive to the adsorption, diffusion and desorption of gas molecular.

The synthesized materials were characterized by using Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR) and Thermogravimetric Analyzer (TGA) in order to determine structure, type of bonding and thermal stability.
Moreover, the resulted structures showed the formation of multiple hydrogen-bonding in the elastomers.
