Titanium phosphate is a plate-shaped filler with characteristics such as high refractive index (1.79), high whiteness, and photocatalytic inactivity. Our unique synthesis technology allows us to provide particles with uniform size and thickness. In recent years, to reduce the emissions of PFAS, which are difficult to decompose and have the potential for long-term environmental persistence, regulations are being considered in Europe, leading to a narrowing of material options in the solid lubricant industry. Titanium phosphate has the following three characteristics as a solid lubricant: 1) When added to grease, it improves durability (resistance to seizure and wear). 2) Due to its high whiteness, it does not cause black contamination in the surrounding area. 3) Depending on the particle size, it can maintain its plate-like shape up to around 700°C. Additionally, it tends to excel in durability compared to common solid lubricants such as molybdenum disulfide, PTFE, and boron nitride. Furthermore, titanium phosphate has the following optical characteristics: - It achieves both light diffusion and light transmission. Light-diffusing particles represented by acrylic particles and silicone particles also have excellent light diffusion properties, but materials that can achieve compatibility with light transmission are rare, making it promising for applications in light-diffusing films and light-diffusing plates.

The cemented carbide punch shown in the image was fabricated by Japan Layered Manufacturing Co., Ltd.

In recent years, the high functionality of communication and mobility has led to issues with heat generation in electronic devices, increasing expectations for heat dissipation materials. Zinc oxide, like common alumina (aluminum oxide) and magnesia (magnesium oxide), has high thermal conductivity and possesses the following advantages: - Low Mohs hardness, resulting in low aggressiveness towards equipment used to manufacture heat dissipation materials - Low thermal expansion coefficient, leading to minimal impact on dimensional changes of heat dissipation materials - Superior water resistance compared to magnesia Our company has successfully developed rod-shaped zinc oxide using our unique particle synthesis technology. Rod-shaped zinc oxide is expected to have three effective benefits for heat dissipation materials: 1) Its high aspect ratio makes it easy to form thermal conduction paths 2) Its rounded corners, due to the crystal structure, make it easy to fill into resins and other materials 3) It is easier to secure contact surface area between fillers compared to spherical particles If you have any of the following challenges, please feel free to contact us: - You want to try heat dissipation/thermal conduction fillers with unique shapes - You are struggling with the difficulty of filling boron nitride fillers (to be combined as a bulking filler) - You are facing issues with water resistance measures for aluminum nitride

In recent years, to reduce the emissions of PFAS, which are difficult to decompose and have the potential for long-term environmental persistence, regulations are being considered in Europe. This has narrowed the options for materials in the solid lubricant industry, and alternatives to PTFE are limited. In response to such challenges, we have developed titanium phosphate in a plate-like form with a controlled aspect ratio. Our synthesis technology allows for control of particle sizes from 0.3 to 5 µm, providing uniform plate-like particles. Plate-like titanium phosphate has the following three characteristics for solid lubricant applications: 1) Excellent sliding properties due to the shape characteristics of the plate-like particles. 2) High whiteness, which prevents black contamination of the surroundings. 3) Composed of materials that do not contain fluorine compounds.
