Alumina ceramic, or aluminum oxide (Al₂O₃), is one of the most versatile and widely used materials in the industrial ceramics sector.

Optical coatings are thin layers of material applied to the surface of optical components, such as lenses, mirrors, and prisms. These coatings play a crucial role in controlling the way light interacts with optical surfaces, improving properties such as reflection, transmission, and durability.

Crucibles play a vital role in laboratory testing, providing a controlled environment for conducting experiments and analyzing samples. One type of crucible that has gained popularity in recent years is the sintered crucible.
