Aluminum oxide, also known as alumina (Al₂O₃), is a remarkable ceramic material widely used in industries ranging from aerospace and electronics to abrasives and refractory linings. One of its most notable properties is its exceptionally high melting point, which enables it to withstand extreme temperatures and harsh environments. This article explores the scientific reasons behind the high melting point of aluminum oxide, delving into its atomic structure, bonding characteristics, and physical properties. We will also discuss the practical implications of this property in various applications. Read More
