At Trio Ceramics, we have started the production of silicon nitride. Silicon nitride is a type of non-oxide ceramic known for its excellent wear resistance (as a liner), toughness, thermal shock resistance, and mechanical strength at high temperatures. It is primarily used in components that operate in harsh environments at high temperatures, such as protective tubes for aluminum molten metal, heater tubes, stokes, and parts for engines and turbines. Trio Ceramics has acquired production facilities for silicon nitride and established a new factory. We are setting up a production system and also planning to maintain a regular inventory of the material. *For more details, please contact us.*

For a long time, our company has walked the path related to ceramics, and we have stepped into the realm of grinding processing, discovering the world of "machinery" and "engineering." In this world, there are traditional skills passed down from old times and cutting-edge new technologies. To fuse and develop these, we decided to establish "Trio Engineering." This world of engineering is also an incredibly vast and endless "path of craftsmanship." Over the next 50 years and 100 years, we want to take small but certain steps to ensure that the wonderful "skills" and "wisdom" are passed down to future generations. We aim to embark on new challenges and strive forward in our daily endeavors. Additionally, we will continue to walk alongside "Trio Shoji Co., Ltd." with the goal of being a company that can contribute to the industrial world, albeit with limited power. *There is also a "Trio Engineering" page within Ipros.
