Provided is a thermal-spray material capable of forming, with satisfactory productivity, a thermal-spray coating film which is constituted of a ceramic having a dense and fine structure. The thermal-spray material provided by the present invention contains ceramic particles having an average particle diameter of 30 µm or smaller and a specific surface area of 0.5 m 2 /g or larger. In a preferred embodiment, these ceramic particles are in the form of secondary particles each made up of primary particles three-dimensionally bonded together so as to leave interstices thereamong. |
