ha ha ha . . .whew. . .
sorry, just had to chuckle
"that was a retarded comment" followed by "u need to make a titanium brain"
wow.
good luck with your ceramic seal development.
better lookout glassman, i think your market share is about to fall off
thanks for this

nippon steel have made seals for 787 for 1989 24 hour race, they have done alot of "r&d". more then glassman x3...It might be the company thats making seal for him. ima give them a call

i can also pretty much guarantee you it isn't silicon nitride ceramic, though perhaps someone has tested it the yield strength is still far too low.
OEM cast iron the shear strength of the mazda seals is over 120,000psi.
non porous alumina is probably the highest rated for the temperatures it may see but it still has only a fraction of the tensile strength of the cast iron seals which are still quite brittle. next closest would be zirconia ceramic which is much closer but it breaks down under extreme heat above 1500F.
the benefit ceramic has is it will not see the same temperatures that the metallic seals will, so it will hold a higher shear strength longer.
yes i know, holy thread resurrection but i'm doing research.
zirconia is generally made for bearings and cutlery since it has a high shear strength, holds an edge but isn't nearly as strong under extreme temperatures. problem isn't only finding raw material it is also cutting it, requiring diamond cutting equipment.
