Nano-structured particles with high thermal stability

The invention relates to ensure with the upper section face area and high fever stable nanometre structure particles. Through the aged nano-particles precursor, a processing them of the recesses state, the people can producing to be in the nanometre structure of the catalyst for. Is increased stabilizer, the people further can improve the upper thermostability. The nanometre structure of tundish for advantageously catalyst for or the use of catalytic agent of the high-temperature.
