利用沙漠砂合成硅酸盐材料——硅酸盐工业和沙漠治理可持续发展的新方向

Use of desert sand to synthesize silicate materials:A new sustainable-development direction of silicate industry and desertization governance

为揭示利用沙漠砂合成硅酸盐材料的优势和重要性,以内蒙古西部库布齐、乌兰布和、腾格里和巴丹吉林4大沙漠为例,通过实地考察并在沙漠边缘取样,研究了该沙漠砂的理化性质。总结了国内外沙漠砂材料的研究和应用现状,分析了利用沙漠砂合成硅酸盐材料的社会效益和经济效益,指出了其发展前景和面临的主要问题。

In order to clarify the advantages and significance of using desert sand to synthesize silicate materials,the author’s team has on-site investigated four deserts,namely Hobq,Ulanbuh,Tengri and Badain Jaran in the western Inner Mongolia of China,collected sand samples around the deserts and studied their basic physical and chemical characteristics.The research and application of desert-sand materials at home and abroad are also summarized,the social and economic benefits of using desert sand to synthesize silicate materials are expounded,and ultimately,the development prospects,main problems and countermeasures are pointed out.It is suggested that existing issues require comprehensive researches in term of the materials and manufacturing science,ecological environment,resource management,and policy to form a clear development goal and specific actions shared by the whole society.The results of this paper have important value for research,development,and application of desert-sand materials,exploitation of mineral resources,and desertization governance.
