WebAug 1, 2001 · The age-related graphitization of carbon and/or low-alloy steel in elevated-temperature fossil plants (or other) service is an example of secondary graphitization. In contrary to expected primary ... WebThe low degree of graphitization of carbon in the shell structure has a lower dielectric constant, which effectively reduces the dielectric constant of the ZIF-67 derived composites and is beneficial to the impedance match. In addition, the presence of the shell structure enables as-prepared composites to maintain a complete cubic octahedral ...
