Many metal oxides and some tungstate have the electrical conductivity and thermal insulation properties, and can be used as infrared shielding material. By heating the mixture solution of ammonium metatungstate (AMT) and alkali carbonate to 80°C, it can prepare some kind of tungsten oxide and tungsten bronze, and all these resulting substances can be used as the raw material of light transmission conductive films with infrared shielding property. Thermal insulation additive is a kind of material which can stop the…

With the rapid development of modern science and technology, all kinds of high-energy rays (such as X-ray) have been more and more widely applied. Besides, since people have put more and more concern to the protection of high-energy rays, and thus, the research and manufacture of X-ray protection materials is emerging in endlessly. There are three ways for X-ray protection, respectively time, distance and shielding protection. Wherein, the shielding protection is using or setting a kind of shielding material which…
