"Disintegrating Frac Balls One of the key challenges in using frac balls is ensuring that they are fully removed after fracturing each stage. To overcome this challenge, a new generation of frac balls has been developed using controlled electrolytic metallic nanos- tructured material that is lighter than alu- minum and stronger than some mild steels, but disintegrates when exposed to the appropriate fluid. The disintegration process works through electrochemical reactions that are controlled by nanoscale coatings within the composite grain struc- ture."
