在过去的几年里，通过“地聚合物”等新材料和“溶胶-凝胶”等新技术的发展，取得了惊人的技术进步。在地聚合反应的帮助下设计的最先进的新材料正在开辟新的应用和程序，并改变无机化学中被认为理所当然的想法。高温技术不再需要获得结构和性能类似陶瓷的材料。这些材料可以像有机聚合物一样在低于100摄氏度的温度下进行缩聚。这种新一代材料，无论是纯使用，还是添加填料或增强，都已经在所有工业领域得到了应用。例如：纯的：用于储存有毒化学或放射性废物等；填充：用于制造特殊混凝土，成型热塑性塑料的模具等；增强：用于制造模具，工具，铝合金铸造厂和冶金等。这些应用可以在汽车和航空航天工业，有色金属铸造厂和冶金，土木工程，塑料工业等中找到。
Spectacular technological progress has been made in the last few years through the development of new materials such as ‘geopolymers’, and new techniques, such as ‘sol-gel’. New state-of-the-art materials designed with the help of geopolymerisation reactions are opening up new applications and procedures and transforming ideas that have been taken for granted in inorganic chemistry. High temperature techniques are no longer necessary to obtain materials which are ceramiclike in their structures and properties. These materials can polycondense just like organic polymers, at temperatures lower than 100 deg. C. This new generation of materials, whether used pure, with fillers or reinforced, is already finding applications in all fields of industry. Some examples:pure: for storing toxic chemical or radioactive waste, etc.filled: for the manufacture of special concretes, molds for molding thermoplastics, etc.reinforced: for the manufacture of molds, tooling, in aluminum alloy foundries and metallurgy, etc.These applications are to be found in the automobile and aerospace industries, non-ferrous foundries and metallurgy, civil engineering, plastics industries, etc.
