Abstract:
It is not quite difficult to demonstrate the narrow relationship existing between the chemistry of cements and the chemistry of ceramics. In fact there exist some very well known hybrid process for fabricating ceramic elements through the routes followed in cement manufacture. For example, refractory materials from high alumina cement. If mechanisms of formation of cements and ceramics are checked it is easily deduced that: a) several alternative mechanisms are possible for both type of materials; b) one only sol-gel mechanism could explain the synthesis for both type of materials. Even, when comparing cements and ceramics, another very interesting common characteristic can be found. The production of such Ceramic Matrix Composites is usual as cements like ceramics are brittle materials. In this paper a general view of Mineral Alkaline Polymers is given. These type of materials are gaining more and more interest as they can be considered like an important connecting element between conventional cements and traditional ceramics. Mineral Alkaline Polymers can be produced by attacking some particular clay minerals, or industrial by-products, with a highly concentrated alkaline dissolution. Some aspects concerning the synthesis, characterisation, properties and applications of Mineral Alkaline Polymers are presented.
