Combination of materials for mercury-dispensing devices and devices containing said combination of materials |
摘要 |
An improved mercury-dispensing combination of materials is made up of a compound A including mercury and a second metal selected among titanium, zirconium and mixtures thereof and an alloy or an intermetallic compound B including copper and tin, said mercury-dispensing combination of materials further containing an amount of oxygen comprised between 0.03% and 0.48% with respect to the overall weight of the composition A+B. It is also possible to add a getter material C that includes metals such as titanium, zirconium, tantalum, niobium, vanadium and mixtures thereof or their alloys with other metals such as nickel, iron, aluminum. |

1. A mercury-dispensing combination of materials, comprising:
a mercury-dispensing powder compound A including mercury and a second metal selected among titanium, zirconium and mixtures thereof; and an alloy or an intermetallic powder compound B including copper and tin, copper being present in an amount comprising between 35% and 90% by weight with respect to the weight of said compound B,
wherein the mercury-dispensing combination of materials further contains an amount of oxygen comprised between 0.03% and 0.48% with respect to the overall weight of the mercury-dispensing combination of materials, andwherein the alloy or intermetallic compound B further contains at least a third metal selected among the transition metals iron, nickel, manganese and zinc and wherein the transition metals are present in an amount not greater than 1% of the overall weight of compound B. |
