Color perception, through radiation of visible light, the light of the material meeting some wave bands of selective absorbing, and shows the face of the light of its commplementary wave length
Color.In the range of visible ray, wavelength is different, produces different colour visions.Color shown by material is that it absorbs minimum that
The color of a part of visible ray.
Zirconia ceramics has high intensity, high rigidity, and good toughness is corrosion-resistant to wait premium properties, is widely applied to each
Field., can be with if colorful translucent polycrystalline zirconia material is made because zirconia ceramics has higher refractive index
It is beautiful as heaven and earth jewel.As people improve constantly to the demand of ornament, colored zirconia ceramics are with its excellent machine
Tool performance, chromatic colour, metallic luster and the features such as acted on without allergy, the new material as top grade decoration.But production at present
Colored zirconia ceramics color it is more dull, mostly black and white, thus colored zirconia ceramics research and development have it is wide
Market prospects.
The preparation of common color ceramics is usually that colouring agent or colorant are added in ceramic idiosome or glaze, passes through high temperature
Burn till（General temperature is less than 1300 DEG C）And obtain.And the sintering temperature of zirconia ceramics is higher, 1400 ~ 1650 are commonly reached
℃.At this temperature, most colorant or colouring agent can decompose, volatilize and no longer develop the color or color reduction.Therefore, simply add
The method of additive color material or colouring agent, it is difficult to the bright-coloured colored zirconia ceramics of colour generation are made.
