    Aluminum Oxide—Aluminum oxide is high strength.
    High-Purity Aluminum Oxide Ceramic—High-purity aluminum oxide ceramic resists shrinking in casts, has a low level of contamination, and is a strong electrical insulator. It’s often used for constructing furnaces and handling liquid metal.
    Silicon Carbide—Silicon carbide has a high heat transfer rate, making it ideal for use in metal casting molds. It has the added benefit of excellent erosion and oxidation resistance.
    Silica—Silica withstands rapid changes in temperature without cracking and has a low rate of thermal expansion.
    Zirconium Oxide—Zirconium oxide is often used in metal handling applications. In addition to its high temperature resistance, it’s also chemical resistant.
