Abstract
Methods of preparing boron suboxide are provided herein. In some embodiments, a method for preparing boron suboxide may include loading elemental boron powder into a furnace; purging the furnace by flowing a first gas comprising one of nitrogen or an inert gas into the furnace; heating the boron powder in a reactive atmosphere comprising a mixture of argon and a non-reducing oxygen-containing gas to convert elemental boron powder into boron suboxide powder, wherein the amount of oxygen in the reactive atmosphere is no greater than about 1%.
Claims20
A method of preparing a boron suboxide powder, comprising:
- loading elemental boron powder into a furnace;
- purging the furnace by flowing a gas selected from the group consisting of nitrogen or another inert gas and mixtures thereof into the furnace;
- heating the boron powder in a reactive atmosphere comprising a mixture of an inert gas and a non-reducing oxygen-containing gas to convert elemental boron powder into boron suboxide powder, wherein the amount of oxygen in the reactive atmosphere is no greater than about 1%;
- and
- removing the boron suboxide powder from the furnace.
A method of preparing a boron suboxide powder, comprising:
- loading elemental boron powder into a furnace;
- purging the furnace by flowing nitrogen, an inert gas, or a mixture thereof into the furnace;
- heating the boron powder to a temperature of about 1200 degrees Celsius to about 1500 degrees Celsius and at a pressure of about atmospheric pressure in a reactive atmosphere comprising a mixture of argon and water vapor to convert elemental boron powder into boron suboxide powder, wherein the amount of oxygen in the reactive atmosphere is no greater than about 1%;
- agitating the boron powder within the furnace;
- and
- removing the boron suboxide powder from the furnace.
