Hibonite is a rare calcium-aluminum oxide mineral that is found in meteorites and is a source of aluminum. It has the chemical formula CaAl12O19. Due to its unique properties, it is sometimes referred to as a "super mineral". Synonyms for hibonite include vonbezingite, khibinskite, and hydrogrossular. These minerals are similar to hibonite in terms of chemical composition and crystal structure. However, they may have different physical and chemical properties, such as color, density, and hardness. Studying these minerals can provide valuable insights into the formation of planets and the composition of the universe.
