Limits Beyond the Sky for Ceramic Materials
Silicon nitride has "the right stuff" for demanding applications such as aerospace and defense.
The phrase “the sky’s the limit” became a cliché way back before the modern airplane. Now that we have the ability to actually fly around in the sky, we need to come up with a better saying. “Space is the limit” doesn’t have much of a ring to it. “The universe’s the limit” is too awkward, not to mention contradictory. Whatever we come up with, the truth is that “the limit” is being extended all the time—and often with the help of ceramic components.
Several advanced ceramic materials feature properties that make them particularly beneficial for use in harsh environments. Silicon nitride, in particular, has “the right stuff” for demanding applications such as aerospace and defense.
“Silicon nitride can replace legacy materials used in ball bearings, radomes and RF windows for extreme applications,” write the authors of “Silicon Nitride: From Supersonic to Hypersonic,” which can be found in this issue. “Resistance to otherwise normal mechanical wear and tear, oxidation, and thermal shock make silicon nitride a uniquely useful material that spans multiple industries.”
Exhibitors and speakers at Ceramics Expo 2019 will share details regarding their latest technologies and how they are helping push the limits in additional application areas such as electronics, biomedical, energy, and many more. Take a look at “Triple Win for Ceramics Expo” for details.
