Summary

Sol-gel derived alumina was shown to produce microcomposite ceramic structures with microplastic properties at room temperature, achieving high strength through localized flow at structural defect sites. Understanding how microplastic flow in composite ceramics can be engineered through processing parallels ongoing research into modifying polymer composite structures to reduce microplastic generation.

The possibility of production of Al2O3 with a microcomposite structure and microplastic properties from solgel compositions at room temperatures is considered. It is demonstrated that high strength parameters are achieved owing to fluidity sites. The Al2O3 obtained from periodic sol-gel solutions can be used as a matrix for microcomposite ceramic material.
