Sponge titanium is a porous form of titanium produced through a chemical reduction process. It is created by reducing titanium tetrachloride with magnesium in a vacuum or inert atmosphere, resulting in a spongy, metallic material. This form of titanium is essential for further processing, as it can be melted and shaped into various products. Due to its lightweight and high strength, sponge titanium is widely used in industries such as aerospace and medical implants. Its unique properties make it ideal for applications where durability and resistance to corrosion are crucial, contributing to advancements in technology and engineering.
