Explaining the material characteristics of GaN and how they relate to its practical performance advantages in power electronics!
In 2026, Technical Ceramics was published by AZO. The content spans approximately 80 pages and covers topics related to material development and processes. This eBook suggests issues related to processes, including explanations of why problems are occurring. Against the backdrop of decarbonization and the increasing power demand of AI infrastructure, gallium nitride (GaN) is gaining attention as a power semiconductor that exceeds the physical limits of silicon. On page 69, "The Role of Gallium Nitride in Power Electronics" explains the material characteristics of GaN, such as wide bandgap, high breakdown electric field, high electron mobility, and thermal stability, in comparison with Si and SiC. It also introduces specific application examples, including onboard chargers for EVs, data center power supplies, solar inverters, and fast chargers. The performance of devices is supported by the quality of substrate materials. Please read this as a prompt to reconsider the pre-treatment and heat treatment of material evaluation. *For more details, please download the PDF or feel free to contact us.*

Company information
Varda Scientific covers a wide range of products, from sample grinding, crushing, homogenization, and heat treatment for laboratory use, to particle size measurement, component analysis, cutting, polishing, embedding, and hardness testing. Varda Scientific has five brands: Leco, QATM, Carbolite Gero, Eltra, and MRB. Since 1999, we have been operating as Leco Corporation, handling products from Leco and Leco Technology. On January 1, 2014, we began handling Carbolite Gero, and at the same time, in line with the increase in the number of brands we handle, we changed our company name to Varda Scientific Corporation. In 2018, we started handling ATM and Qness, and in June 2019, MICROTRAC and Microtrac Bell joined the Varda Scientific Group. As of May 1, 2020, ATM and Qness merged to become QATM, further enhancing our capabilities and allowing us to better meet our customers' needs.
