Abstract
The invention provides a manufacturing method for gray zirconia ceramics, which comprises the following steps: providing white zirconia ceramics; placing zirconia ceramics in a vacuum graphite furnace to be fired at a high temperature to produce black zirconia ceramics; and oxidizing and sintering the black zirconia ceramics in a sintering furnace to obtain the gray zirconia ceramics. According to the manufacturing method for gray zirconia ceramics, the gray zirconia ceramics are obtained through high temperature firing, the color is fashionable and permanent, and products made of the gray zirconia ceramics are attractive in appearance and fashionable in color.
Description
Technical field
The present invention relates to the stupalith field, relate in particular to a kind of making method of canescence zirconia ceramics.
Background technology
Stupalith is widely used in the fields such as building materials, utensil and ornament, and the product that wherein zirconia ceramics material is made is because of good characteristics such as its hardness is high, wear-resistant, good toughness, electroless plating pollutions, very popular.Zirconia ceramics product in the market, as ceramic wrist-watch, is solid color mostly, and its color is to obtain by adding therein toner, and for the interpolation of toner, wayward, and the color formed is not lasting.
Summary of the invention
A purpose of the present invention is, a kind of making method of canescence zirconia ceramics is provided, and can obtain the canescence pottery, attractive in appearance with the ornaments of its making, color fashion is permanent.
For achieving the above object, the invention provides a kind of making method of canescence zirconia ceramics, it comprises the steps:
Step 1, provide white zirconia ceramics;
Step 2, be placed in the Vacuum graphite oven high-temperature firing by white zirconia ceramics, generates black zirconia ceramics;
Step 3, be placed in the sintering oven oxidation and sinter by black zirconia ceramics, obtains linen zirconia ceramics.
In step 2, firing temperature is 1400-1550 ℃, insulation 1-4 hour.
In step 3, sintering temperature is 600-1000 ℃, insulation 0.5-4 hour.
In step 3, black zirconia ceramics in sintering oven under natural atmosphere oxidation and sinter.
Beneficial effect of the present invention: the making method of canescence zirconia ceramics of the present invention, obtain the canescence zirconia ceramics by high-temperature firing, color fashion is permanent, attractive in appearance with the product of its making, color fashion.
Embodiment
The invention provides a kind of making method of canescence zirconia ceramics, comprise the steps:
Step 1, provide white zirconia ceramics as raw material, and it can be the zirconia ceramics that prior art obtains, and can have predetermined shape, as the shape of the products such as wristwatch case, various jewellery.
Step 2, be placed in Vacuum graphite oven by white zirconia ceramics, under 1400-1550 ℃, fires, and insulation 1-4 hour, generate black zirconia ceramics.Fired rear employing naturally cooling.
Step 3, by black zirconia ceramics oxidation and sinter in sintering oven, sintering temperature is 600-1000 ℃, insulation 0.5-4 hour, obtain linen zirconia ceramics.Wherein black zirconia ceramics in sintering oven under natural atmosphere oxidation and sinter, after sintering, product adopts naturally cooling.In step 3, described canescence is mixed into by black and white, and temperature is higher, the time is longer, and white proportion is larger, by controlling sintering temperature and time, generates required color effects.The canescence zirconia ceramics that this makes has greyish white alternate marble lines, presents greyish white alternate effect, and has the quality of beautiful matter effect, excellent in appearance.
This making method of the present invention can be applicable to the making of various products as various jewellery, wrist-watch etc., the product of making fashion attractive in appearance, and its color had is different from prior art adds toner formation, therefore colour-fast, permanent.
In sum, the making method of canescence zirconia ceramics of the present invention, obtain the canescence zirconia ceramics by high-temperature firing, and color fashion is permanent, attractive in appearance with the product of its making, color fashion.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of the accompanying claim of the present invention.
