Abstract
A method of making Si3N4 nanotubes and nanorods comprising adding agricultural husk material powder to a container, wherein the container is a covered boron nitride crucible, creating an inert atmosphere of nitrogen inside the container, applying heat, heating the agricultural husk material, and reacting the agricultural husk material and forming silicon nitride, wherein the silicon nitride is nanotubes and nanorods.
Claims10
A method of making Si3N4 nanotubes and nanorods comprising:
- adding agricultural husk material powder to a container;
- wherein the container is a covered boron nitride crucible;
- creating an inert atmosphere of nitrogen inside the container;
- applying heat;
- heating the agricultural husk material;
- and
- reacting the agricultural husk material and forming silicon nitride;
- wherein the silicon nitride is nanotubes and nanorods.
A method of producing nanorods and nanoparticles of silicon nitride comprising:
- washing husks in distilled water;
- pulverizing husks into fine husk powder using high energy mill with stainless steel milling media;
- pressing the fine husk powder into pellets;
