For any semiconducting metal oxides, dielectric properties of nanomaterial play an important role, which determines various activities such as sensing, catalytic activity, adsorption, etc. These properties depend on the chemical composition, method of synthesis and surface characteristics. Various physical and chemical properties of nanomaterials can be tuned by choosing various chemical treatments...
The effect of α-alumina seed particles on the densification and microstructure development of the sol-gel derived alumina-zirconia composites has been studied. The alumina-zirconia sols have been prepared from two different alumina sols (polymer and particulate) and two different types of zirconia particles. Addition of the seed particles decreases the θ to α-alumina transformation temperature by...
