Applications
Sensors, including gas sensors, medical parts, electrodes, heaters, probe-pins, etc.
Prevents decrease in strength caused by crystal grain coarsening in high-temperature environments, increasing the range of applications in harsh temperature environments.
In high temperature environments, crystal grains become coarse, causing a significant decrease in strength. With nanoplat™, a strengthened platinum material with dispersed ZrO2 particles developed by TANAKA, the dispersed oxide particles work to hold the crystal grains together even at high temperatures, reducing the coarsening of the crystal grains and thereby preventing a decrease in strength and extending the lifespan.
Features
- Prevents crystal grain coarsening in high temperature environments and reduces strength loss
- Has the same electrical properties as the base Pt

nanoplat™BP
→For wire development of materials for platinum alloy equipment for glass manufacturing. Due to the presence of coarse oxide particles, can be used with wire diameters of Φ250µm and above.
nanoplat™TPW
→nanoplat™BP’s fine wire processing product. Fine oxide particles enable fine wire processing.
nanoplat™PW
→Although it has less strength due to the improvement of nanoplat™TPW’s thinning and reduction of Zr, it can be processed up to Φ15µm.
nanoplat™APW
→By adopting special coating technology, it provides low-cost support in the fine wire area.
