| titleOfInvention | Preparation method of nano NTC ceramic powder suitable for tape casting and tape casting film |
| abstract | The invention discloses a nano NTC ceramic powder suitable for tape casting and a preparation method of a tape casting film, wherein the nominal chemical composition of the NTC ceramic powder is Mn 3‑x‑y‑z Ni x Fe y M z O 4 M represents Sn, Cu, Ti, Al; the preparation method comprises the steps of taking acetate, oxalate and oxalic acid which form cations as starting raw materials, controlling the molar ratio of all the cations to all oxalate ions, blending, grinding and mixing, drying at 80 ℃ for a certain time to reach a certain viscosity, heating to a certain temperature at a certain heating rate, and keeping the temperature for a certain time to obtain the NTC ceramic powder which is suitable for tape casting and has a fluffy average particle size of 250-400 nanometers, wherein an organic solvent route is adopted for preparing a tape casting film, an acetone isopropanol solution is adopted as a solvent, tributyl phosphate is adopted as a dispersing agent, an isopropanol solution of PVB is adopted as a binding agent, and DBP is adopted as a plasticizer. The preparation method can obtain the nano ceramic powder with accurately metered components, is environment-friendly and is suitable for batch production; the obtained ceramic powder has good tape-casting formability. |
