👉 Kentallenite, also known as beryllium nitride (B4F6) or B4F8, is a type of solid that forms when nitrogen atoms are replaced by boron atoms. It is a very hard and brittle material with a high melting point and low density. Kentallenite has the following properties: 1. High tensile strength: Kentallenite can withstand extreme stress without breaking. 2. High hardness: Kentallenite is highly resistant to wear, which
