boric oxide
Quick Summary
Boric oxide, also known as boric anhydride, is the trioxide of boron with the chemical formula B2O3. It is typically obtained as a transparent, glassy solid by fusing boric acid. Boric acid (H3BO3) is a white crystalline acid of boron found in certain minerals and volcanic waters. Boron itself is a semimetal essential for plant growth and has various industrial applications. Boric oxide is formed when boric acid is heated and loses water.123
