Ultrahigh-temperature ceramics are promising materials for protecting aircraft wings from friction during hypersonic flight—but thermal shock can cause these ceramics to crack. In the cover article for the March 2020 International Journal of Ceramic Engineering & Science, researchers in China report how wing shape affects thermal shock behavior of UHTCs.

Sol-gel is a relatively inexpensive and easily controlled coating method to potentially strengthen glass. In a recent ACerS journal article, researchers look at the three key factors affecting the ability of sol-gel coatings to strengthen glass: elastic modulus, residual stress, and filling ratio.

Just as car models build upon the successes and failures of the previous generation, so too do journal articles. See how such a process takes place through the comparison of two JACerS articles from 1981 and 2019 on indentation crack testing.

Fabricating dense, complex-shaped items from silicon carbide can be challenging due to the material’s properties. Manufacturers benefit from studies on reducing viscosity of SiC slurries, such as two recent ones published in an ACerS journal, but open access to the data behind such studies may benefit them even more.

Faster than a speeding bullet: A review on fiber reinforced UHTCMCs for hypersonic aircraft and more
Ultra-high temperature ceramic matrix composites could be used on some of the hottest portions of hypersonic aircraft if their brittleness is reduced. Research on using fibers to reinforce these materials increased greatly in the past decade, and a recent review article in an ACerS journal discusses the progress and challenges in this field.

Porous ceramics hold great promise as value-added products for waste materials because they can use ceramic and glass powders as starting materials. Two recent papers published in a special issue of ACT explore this idea by creating foam glass from waste.
