Boros

Boros is a chemical element with the symbol "B" and atomic number 5. It is a metalloid, meaning it has properties between metals and nonmetals. Boros is typically used in high-strength, heat-resistant materials, such as borosilicate glass (like Pyrex), insulators, and ceramics. It appears as a black or dark brown crystalline substance and is rarely found in free form in nature but is part of compounds like borates and borax. Its unique properties make it valuable in industry, electronics, and chemical manufacturing.
