Features of the Thin Film-Coated Powder (TFCP)
TFCP provides a smooth and precision-controlled nano-film on each particle of the base material powder (particulate).
Its features are presented below.
Synthesis through solution reaction process
Schematic diagram of the coating process
 |
- In TFCP, the nano-film is formed through a solution reaction. It is a desirable formation method for powdery base materials.
- Through a solution reaction, it is possible to generate a film precipitation that can coat the surface of particulate base material evenly, thanks to the surface energy of the base material particles in the solution. Moreover, a precision nano-film can be formed by promoting the reaction while retaining the dispersion state of base material particles in the solution.
- Please refer to the page "Principles of TFCP film formation" for details of the formation method.
Optical effects
Light interference by the multi-layered films
 |
- Because TFCP possesses a smooth and precision-controlled nano-film, it exhibits excellent optical properties.
- When coated with light interference film (dielectric film), brilliant interference color is generated even when the base material particle is opaque or the film is thin. Interference colors are shown in spherical form for spherical powder particles and in a plate form for plate-like powder particles.
- When coated with a light reflecting film (metallic film), high light reflection is exhibited even if the film is thin. When coated onto magnetic particles, highly magnetic white particles result.
- When dielectric film is formed on fluorescent particles as an insulating layer, luminescence intensity is improved.
Anti-oxidation properties
Excellent acid and heat resistance
 |
- TFCP with its smooth film controlled down to the nanometer level exhibits excellent acid resistance, anti-oxidation properties and heat resistance.
- When particles that are easily dissolved or oxidized with acid or heat, or those that undergo phase change accompanied by swelling are coated with silica or other nano-films, excellent acid resistance, anti-oxidation properties and heat resistance are exhibited.
- These effects are achieved for the first time with this smooth and minutely structured film.
