Abstract: A thermal insulating cover which can be easily fitted on an object. [Means for solution] A thermal insulating cover 10 to be fitted on a battery B so that a wall portion 12 in a cylindrical form of the cover covers the entire periphery of the side surface of the battery B. The wall portion 12 has a general portion 18, which is disposed to be separate from the side surface of the battery B, and a sealing portion 20, which is formed to protrude inward more than the general portion 18 and elastically abutting on the side surface of the battery B. The thermal insulating cover 10 closes an upper side of a space G formed between the side surface of the battery B and the general portion 18 by the sealing portion 20.

Abstract: The present invention provides a method of synthesizing hydroxy apatite comprising the steps of preparing a mixed material slurry by dispersing calcium hydroxide (Ca(OH)2) powder into a phosphoric acid (H3PO4) solution; conducting a mechanochemical milling treatment in which shearing force and compressive force based on a centrifugal force of a mechanical rotating body are imparted to the mixed material slurry, and reacting the calcium hydrate component with the phosphoric acid component under normal temperature and pressure thereby to prepare hydroxy apatite (HAp) powder having fine crystals. According to the structure described above, there can be provided a method of synthesizing hydroxy apatite having fine and uniform particle size which can be directly synthesized under normal temperature and pressure in a short time through simple and single process.

Abstract: The present invention provides a method of manufacturing calcium phosphate powder comprising the steps of preparing a mixed material by mixing calcium hydroxide (Ca(OH)2) powder and calcium hydrogenphosphate powder so that a molar ratio (Ca/P) of calcium to phosphor is set to a range of 1.45-1.72; conducting a mixing/milling treatment to the mixed material to cause a soft-mechanochemical compositing reaction thereby to prepare a calcium phosphate precursor; and conducting a heat treatment to thus obtained precursor at a temperature of 600° C. or more thereby to prepare calcium phosphate powder. According to the present invention, the manufacturing process is simple and the manufacturing cost can be remarkably reduced. In addition, fine calcium phosphate powder excellent in characteristics can be easily manufactured in a short time.
