Latest Patents

One of Ho Yong Lee's latest patents is a method for manufacturing surface-modified alumina-based ceramics. This innovative method involves sintering a powder compact of iron-containing alumina powder in a low oxygen partial pressure atmosphere. The process includes annealing in a higher oxygen partial pressure atmosphere, resulting in an alumina-based ceramic with a grain-boundary migration layer on its surface. This unique feature improves short-crack toughness by suppressing and deflecting crack propagation, thereby enhancing durability and wear resistance.

Another notable patent by Lee is a method for making BaTiO3-based dielectrics. This method aims to produce a dielectric with a high dielectric constant and low dielectric loss. The process involves subjecting a BaTiO3-based body to a pre-heat treatment in a hydrogen atmosphere before the sintering process. This treatment results in a reduced average grain size of BaTiO3, leading to improved dielectric properties.
