We propose bauxite, which has a high thermal conductivity equivalent to α-alumina, as a new thermal conductive filler.
The conventional bauxite has a low thermal conductivity, and its properties were not sufficient for heat dissipation applications. We have developed a high thermal conductivity type of bauxite with a thermal conductivity comparable to that of α-alumina using a special method. By filling it into plastics, rubber, sheets, greases, and other materials, it can impart high heat dissipation and thermal conductivity. Control over particle size (submicron to single micron) and particle shape (cubic, plate-like, flaky, needle-like, etc.) is possible. It can be used in various applications such as thermal conductive fillers, flame retardants, flame retardant aids, reinforcing materials, and abrasives. 【Features】 ■ High thermal conductivity comparable to α-alumina ■ Control over particle size (submicron to single micron) and particle shape (cubic, plate-like, flaky, needle-like, etc.) ■ High decomposition temperature (approximately 500°C) and excellent heat resistance ■ Low Mohs hardness (3.5 to 4) and small specific gravity (3.0 g/cm³) ■ Insoluble in acids and alkalis, demonstrating high chemical stability

Company information
Kawai Lime Industry Co., Ltd. has been manufacturing and selling quicklime, dolomite, and hydrated lime at its three domestic locations since its founding in 1885, with the main production of alumina hydrate bauxite "Serashur" taking place at its headquarters in Minato. The company is also actively engaged in the development of functional inorganic materials that add value based on lime and bauxite. As the Fourth Industrial Revolution progresses, we will incorporate this technology into production and quality management, continuously challenging ourselves to achieve optimal manufacturing and sales.
