Introduction
Black alumina is mostly used in semiconductor integrated circuits and electronic products. This is mainly because most electronic products have high photosensitivity and require a strong light-shielding property of the packaging materials. Black alumina ceramics are often made into ceramic substrates, ceramic packages, ceramic hair straighteners, ceramic heaters.
