Abstract
A method of making Nanostructured Zinc Silicate from renewable sources comprising preparing powders of husks, preparing powders of ZnO, mixing the powders of husks and the powders of ZnO and forming a homogenous sample powder, pressing the homogenous sample and forming pellets, heating the pellets and forming nanostructured zinc silicate. The nanostructured zinc silicate from renewable sources product of the process of preparing powders of husks, preparing powders of ZnO, mixing the powders of husks and the powders of ZnO and forming a homogenous sample powder, pressing the homogenous sample and forming pellets, heating the pellets and forming nanostructured zinc silicate.
Claims7
A method of making Nanostructured Zinc Silicate from renewable sources comprising:
- preparing powders of husks wherein the husks are selected from the group consisting of wheat husk, rice husk, and a combination of wheat husk and rice husk using ball milling including stainless steel milling media;
- preparing powders of ZnO using ball milling including stainless steel milling media;
- mixing the powders of husks and the powders of ZnO using ball milling including stainless steel milling media and thereby forming a homogenous sample powder;
- pressing the homogenous sample powder into disks having a diameter of 1 cm and thickness of 2-3 mm and forming pellets;
- heating the pellets at a temperature above 1400° C. and forming nanostructured zinc silicate pellets of 50-100 nm;
- and
- removing excess carbon by processing the nanostructured zinc silicate pellets in air at a temperature of 650° C.
