Compositions containing getter material and getter devices for which gettering activity can be activated at applied temperatures that are lower than those temperatures required for activating the getter material alone are disclosed. In one aspect, a getter composition that includes a getter component and an activator component is provided. The getter component is selected from the group consisting of evaporable and non-evaporable getter materials. The activator component is effective to heat said getter material to a temperature greater than about 500° C. when said activator material is heated to a temperature of between about 280° C. and about 500° C. In some embodiments, the activator component is effective to bring the temperature of the getter material to greater than about 1,000° C. These materials can be used in devices and locations for which low applied activation temperatures are required.

Composition according to claim 2, characterized in that the particle or particles (6) are loosely arranged in the interior of the cavity (4, 5). 4. Composition according to claim 2, characterized in that the cavity (4, 5) is substantially centrally arranged in the interior of the tablet (1). 5. Composition according to claim 2, characterized in that the particle or particles (6) are fixed in the interior of the cavity (4, 5). 6. Composition according to claim 5, characterized in that the particle or particles (6) are fixed by an adhesive in the interior of the cavity (4, 5). 7. Composition according to claim 2, characterized in that the tablet (1) has a single, substantially spherical cavity (4, 5). 8. Composition according to claim 7, characterized in that the cavity (4, 5) receives a single, substantially spherical particle (6), whose external diameter is smaller than the internal diameter of the cavity. 9. Composition according to claim 1, characterized in that the particle or all the particles (6'; 6") are received in at least one cavity (4') of the tablet (1') and which is only partly surrounded by the base composition (2'). 10. Composition according to claim 9, characterized in that the cavity has a depression (4') in one of the surfaces (11') of the tablet (1') in which the particle or particles (6'; 6") are at least partly received. 11. Composition according to claim 10, characterized in that the cavity or depression (4') is only open so wide to the surface or surfaces (11') that the particle or particles (6'; 6") received therein cannot pass through the opening or openings of the cavity or depression (4'). 12. Composition according to claim 11, characterized in that the particle or particles (6'; 6") are loosely arranged in the cavity or depression (4'). 13. Composition according to claim 10, characterized in that the particle or particles (6'; 6") are so received in the cavity or depression (4') that they do not project over the surface or surfaces (11') of the tablet (1'). 14. Composition according to claim 13, characterized in that the cavity or depression (4') is parallel to one of the surfaces (11'), to which it is open or in which it is located, and has a substantially circular cross-sectional face. 15. Composition according to claim 14, characterized in that the particle or particles (6'; 6") are fixed in the cavity or depression (4'). 16. Composition according to claim 15, characterized in that the particle or particles (6'; 6") are fixed with an adhesive (10') in the cavity or depression (4'). 17. Composition according to claim 1, characterized in that the covering (9; 9'; 9") comprises at least one compound, which is not or is only slightly soluble at the concentration of the specific ion prior to the inflow of fresh water and in which the concentration of the specific ion following the inflow of an adequate quantity of fresh water has a solubility such that it is so substantially dissolved or detached from the core or cores that there is an at least partial escape of the core material into the surrounding medium. 18. Composition according to claim 17, characterized in that the compound comprises K-carrageenan. 19. Composition according to claim 17, characterized in that the solubility of the compound increases with decreasing OH-ionic concentration and therefore decreasing pH-value in the surrounding medium. 20. Composition according to claim 19, characterized in that the compound comprises a polymer. 21. Composition according to claim 20, characterized in that the compound comprises a pH-sensitive polymer comprising at least one repeat unit, which has at least one basic function which is not part of the backbone chain of the polymer. 22. Composition according to claim 21, characterized in that the polymer comprises at least on repeat unit based on a compound selected from the group consisting of one or more vi
