Hello! I am just wondering if anyone would be able to give me a bit of information about CRT displays. I know eMacs use them and I saw the CRT in one break. There was a cloud of gas that came out, and apparently it is phosphorus from the CRT display. Is that correct?
Computer Destruction - Sledgehammer Meets Apple eMac - YouTube - This video shows it breaking (Sadly) (0:55 shows the most gas coming out)
MacBook Air, macOS High Sierra (10.13.1)
Phosphorus is a solid not a gas, and CRTs are a vaccum vessel tht implodes when broken. Likely anything jetting out to the CRT would be outside air that rushes in to fill the now -broken vacuum that rebounds as ambient pressures normalize. Any phosphorus would be in dust form, plus there are insulating coatings on the inside of the tube that would contribute to the dust cloud. Also the violent implosion will reduces some of the broken glass to near powder size.
This Wikipedia article is quite good:

The cloud could also include dust from the outside of the CRT. The high voltage attracts dust.
Thanks for the information!
