In the present study, the synthesis of nano structured materials such as nano alumina (Al2O3), nano silica (SiO2), and nano hydroxyapatite (HAp) have been discussed for industrial applications. The oxide nano materials are prepared employing chemical methods from natural resources. The HAp is prepared employing sol-gel process using chemical precursors. The synthesised nano alumina (Al2O3) powder has been used to improve the physicochemical properties of refractories. The prepared nano particles employing different process techniques have been characterized using XRD, FTIR, EDAX and SEM studies. The silica nano particles have been coated on textiles to get the wrinkle free/antibacterial textile cloths/products. The synthesized nanoparticles from natural resources have been used in various industrial applications such as refractories, textiles and biomedical field.
