From these tests, it was concluded that using fused silica--instead of alumino-silicate for the slurry and stucco (or even for just the slurry)--makes for a more autoclave crack resistant shell.
A comparison of fused silica and alumino-silicate (test specimens made with only backup shells) shows that when both types of shells are held for 2 hr in a preheat furnace at 2012F (1100C), the same dimensions result.
Figure 2 compares hot creep behavior of an all fused silica specimen with another where the slurry was of the low viscosity fused silica type and the stucco alumino-silicate.
ADM's selection of GE as their exclusive provider of PET and fused imaging is a reinforcement of our technology leadership.
GE Discovery Series of fused imaging systems represents one of the most significant technological advancements in medicine in the past 20 years according to healthcare experts.
Fused imaging can be compared to the images shown during a television weather report.
The experiment will determine the long-term effects a space environment has on various materials, one of which is Corning's HPFS(R) fused silica glass material.
The fused silica will remain exposed for approximately 18 months.
Fused components are important passive fiber optic devices used for both splitting and combining optical signals in high capacity transport networks utilizing DWDM technology, as well as for network monitoring applications.
The key to FONS' fused products is our successful development of semi-automated manufacturing equipment and processes that result in high volume capacity, exceptional reliability and low cost manufacturing," states Michael J.
