Yeh, H.C.Chuang, E.W.Liu et al: Ceramics International.
Microwave heating offers advantages such as heating uniform, low sintering temperature, short sinter time and high product density, and it has been used in preparation of ceramic in the early 1990s[[]Ye Lin, Yewen Xu and Zheng Xu: Bulletin of the Chinese Ceramic Society.
This was believed that microwave heating caused different temperature gradient in the sample [[]Yuandong Peng, Jianhong Yi and Yingli Guo: submitted to Journal of Central South University (Science and Technology).
The results may also be due to the accelerating immigrant of the atoms of nitrogen in synthesis processing by microwaves [[]J.G.P.Binner, N.A.Hassine and T.E.Cross: Journal of Materials Science.

This paper describes the concept and connotation of green building materials, combing the domestic and international green building materials research status; analysis on direction and achievements of construction materials, like natural building materials, Cyclic regeneration of building materials, Low environmental load building materials, Environmental functional building materials and Renewable energy use composite material.
Composite materials refer to engineered or naturally-occurring materials made from two or more constituent materials with significantly different physical or chemical properties.
In recent years, the definition of green building materials and basic evaluation system were determined, and the third "China Beijing International Green Building Materials Exhibition" and the "China Green Building Materials Development Forum" were organized.
China only speed up the implementation of the system of environmental labeling certification, in order to place in the international market.
