A process for producing high-porosity non-evaporable getter materials and materials thus obtained |
摘要 |
A process is disclosed for producing non-evaporable getter materials having good mechanical strength, high porosity and improved gas sorption rate, including mixing a metallic getter element, one or more getter alloys and a solid organic compound, with all components being in the form of powders having specific particle sizes. The thus obtained mixture is subjected to compression at a pressure lower than 1000 Kg/cm<2> and sintered at a temperature between 900 and 1200 DEG C for a time between 5 minutes and 1 hour. The thus obtained getter material is used to produce getter bodies shaped as pellets, sheets or discs having an improved mechanical strength with respect to similar bodies obtained by a getter material of known type having comparable porosity values. <IMAGE> <IMAGE> |
