| titleOfInvention | Method for producing hard particles with surface treatment film and hard particles with surface treatment film |
| abstract | A method of producing hard particles with a surface-treated film having good dispersibility by forming a uniform surface-treated film on the surface of inert hard particles such as diamond and CBN using a wet process that can be produced at low cost. I will provide a. A step of preparing hard particles 2 having a Knoop hardness of 1000 or more, and the hard particles 2 are selected from Zr, Ti, Si, Cr, Ta, Hf, Sn, Mo, W, Zn, In and V Holding in an aqueous solution containing one or more metal fluoride complexes to form a hydrated oxide-containing film 3 'of the metal on the surface of the hard particles 2, and hydration of the metal The hard particles 1 with a surface-treated film were produced by a method comprising: drying the hard particles on which the oxide-containing film 3 ′ was formed. It is preferable to provide a contact step with an aqueous solution containing a phosphorus compound between the hydrated oxide-containing film forming step and the drying step.
