Abstract
Zirconia nanofiber mats containing filaments with the average diameter of less than 100 nm were fabricated. It is found that the hardness and Young’s modulus of the mats are sensitive to the microstructure, phase composition and average diameter of the zirconia nanofibers. The hardness and Young’s modulus of the prepared zirconia nanofiber mats vary from 0.86 to 1.67 MPa and from 133 to 362 MPa, respectively, wherein an increase in hardness is accompanied by the rise in Young’s modulus.
Highlights
Among all the variety of nanofibers only ceramic ones possess increased thermal and chemical resistance [1,2]

It is well known that the mechanical characteristics of bulk zirconia ceramics can be significantly improved by adding 3 mol% Y2O3 to pure zirconia to obtain tetragonal zirconia polycrystalline ceramics [4]
Summary

Abstract: Zirconia nanofiber mats containing filaments with the average diameter of less than 100 nm were fabricated. It is found that the hardness and Young’s modulus of the mats are sensitive to the microstructure, phase composition and average diameter of the zirconia nanofibers.
