title = "Characterization of Nano-porous silica-zirconia aerogels",
abstract = "Highly Nano-porous SiO2-ZrO2 aerogels were manufactured with tetraethylorthosilicate (TEOS) and zirconyl nitrate dihydrate (ZrO(NO3)25H2O) by the sol-gel method followed by supercritical drying technique. The prepared aerogels are performed by SEM, FT-IR and BET to characterize and analyze the morphology and pore structure of SiO2-ZiCh aerogels. The results showed that:(i) The areogels are the typical of nano pores in the interval between 1p<30 nm; (ii) the specific surface areas varied from 300 to 620 m2/g with (S BET)MAX = 615.5 m2/g with 35wt\% Zirconia and the surface areas decreased with the increase of zirconia; The thermal conductivity attains 0.015 W/(m k) ; (iii) a mass of Si-O-Zr bands existed in the aerogels indicating a homogeneous distribution of the components on the nano scale.",
