This is fascinating. I am a bit skeptical if this actually happened.

I had an opportunity to meet an engineer that was involved with early 
HDTV development. Apparently early in his career he invented a color 
projection CRT for cinema. It had some sort of target inside of it (I 
think plastic) that was subjected to the electron beam but would outgas 
hydrogen in significant amounts and that hydrogen would ionize in the 
electron beam which was undesired. So they incorporated a band of 
titanium around the neck of the tube and the titanium apparently allows 
hydrogen to collect and migrate through it even though there is a vacuum 
inside the tube. It worked as intended. Then the Chinese tried to 
replicate the design and did not use a titanium band because they had no 
idea it had a purpose. Their tubes failed miserably.
