Abstract

PURPOSE:To enable desirable coloring on various kinds of materials by heating and oxidizing a zinc powder containing a coloring element in a specific temp. range. CONSTITUTION:In the pure zinc powder, about 0.01-10.0wt.% of element of Ti, Mn, V, etc., is added as the adding element for coloring. Particularly, in the case of obtaining the powder after adding the above adding element and pulverizing, this adding element is desirably added to so much extent as about 0.5-10.0wt.% to make this powder brittle. The pulverized powder is heated and oxidized at 350 deg.C-<450 deg.C to obtain the colored zinc powder. In this case, the oxidizing time is for 3sec-100min. According to the length of this time, the various kinds of the fixed color is obtd. For example, in the case of adding titanium, color is changed to blue, dark blue, blue-purple, red-purple, golden, etc.

Colored zinc powder is obtained by heating and oxidizing this pulverized powder at a temperature below 350 to 450°C. Although this temperature is originally below the melting point of the zinc alloy, it is surprising that the powder has a surprisingly vivid color.

Furthermore, in order to obtain more vivid coloring, inert gas (e.g. Ar gas, etc.) or neutral gas (N, etc.) is introduced until the desired oxidation temperature is reached, and then an oxygen-containing gas such as air is introduced. Oxidation is desirable. This is to prevent the grain surface from being oxidized before the temperature rises, which would interfere with color development.

When this alloy powder was used in a temperature range of 350° C. to less than 450° C., the speed at which the color changed as described above became even slower, making it much easier to control the oxide film thickness. That is, as shown in FIG. 1, colored zinc powder having a desired color tone could be obtained at specific temperatures: golden yellow at 350°C, reddish-purple at 400°C, and blue at 425°C.

An alloy containing (m, p, 450°C) was melted at 350°C, and an alloy powder was obtained by spraying with N and gas. In this case, spherical zinc powder was obtained by controlling the atmosphere in the chamber after spraying to have a trace amount of oxygen (3%). Using this raw material, alloy powder was heated in a temperature range of 350°C to less than 450°C. As shown in FIG. 2, colored zinc powder having a desired color tone could be obtained at specific temperatures: golden yellow at 350°C, reddish-purple at 400°C, and blue at 425°C.
