Solutions for Cathode Ray Tubes Cathode Ray Tube (CRT) is still one of the major television industry display technology. In spite of its age, and the onset of new flat screen technologies, the CRT is still by far the least costly technology capable of meeting the consumer display demands. For years flat panel technologies have attempted to penetrate this market, and since year 2000 color Plasma and LCD technologies made significant market growth, mainly due to aggressive marketing strategies and technology improvements reducing manufacturing costs and cost to the consumer. The CRT is a source of electrons (cathode) that must pass through the vacuum and strike the phosphor screen (anode) giving light. When scanned and modulated, the beam can create a high‐resolution image. High vacuum is necessary, otherwise, the cathode will be damaged reducing electron emission and tube brightness. The SAES Getters Group has worked closely with CRT television tube manufacturers since its very first business inception, by developing and marketing getter breakthroughs required to boost CRT lifetime expectancy and performances. With its state‐of‐the‐art laboratories and production facilities, SAES Getters actively partners with the CRT industries worldwide, designing getters to meet production and consumer demands. Continuous innovation of its getter products and breakthrough technologies enable CCRT makers worldwide to achieve very challenging technical targets. SAES Getters promotes deep technical collaboration with its customers, to identify the most viable getter solution for any kind of CRTs, with sizes ranging from 1” for camera viewfinders to 43” for consumer TVs. Through steady investments in R&D and a firm mastering of the production processes involving metallurgy, vacuum technology and getter manufacturing, the SAES Getters Group has developed and supplied an incredible variety of products. Soft Flash Getters improved production of CCRTs with a much lower Arc Current. With the advent of Soft Flash CCRTs, TV sets became less expensive, as the electronic driving circuitry could be drastically simplified. SAES Frittable Getters met the desire of the CCRT industry to design large flat CCRT screen with low stray emission and uniform brightness. Frittable Getters can withstand the sealing process of the funnel and panel sections which require baking in air at a peak temperature near to 450 °C. This feature dramatically increases the freedom of the CCRT industry allowing the CCRT makers the flexibility to mount the getter in the most proper place inside the kinescope. www.saesgetters.com This paper contains no confidential information © 2012 SAES Getters.

In air or in vacuum barium chemically reacts with moisture and gases (except the noble gases like Ar and He), forming stable compounds like oxides and carbonates. The BaAl4 alloy is more stable, thus facilitating the handling of such a reactive element as barium is. The getter is made by compressing at high pressure a mixture of BaAl4 and nickel powders inside a stainless steel container. Boost your product performance with SAES Getters solutions: 
