Abstract
The invention discloses a zirconia load bearing board. The board body is a composite bed structure, which comprises a sandwich load bearing board layer at a lower part and a zirconia composite layer painted on the surface of the sandwich load bearing board layer. The outer layer of the sandwich load bearing board layer is an alumina layer and the inner layer is a carborundum layer. The zirconia composite layer is 0.3 to 0.5mm in thickness and is evenly adulterated with nanoparticles. The zirconia load bearing board of the invention is suitable for electric pushed slab kiln sintering solid ferrite in an electronic component industry, which has the advantages of saving zirconia resources, convenient using and long service life.
Description
Technical field
The present invention relates to a kind of load bearing board of zirconia, the load bearing board of zirconia that uses when particularly being applicable to the electric pushed bat kiln sintered iron of electronic devices and components industry oxygen magnet.
Background technology
In the electronic devices and components industry, high-grade Ferrite needs high temperature to burn till, in sintering process, must be placed on the resistant to elevated temperatures load bearing board of a kind of energy, since very tight when high-grade Ferrite burns till to environmental requirement, can not be placed directly on the common load bearing board, must be placed on the zirconia material.Existing load bearing board of zirconia comprises two-layer, and lower floor is common load bearing board, and the upper strata is the zirconium white small raft.A load bearing board needs several piece zirconium white small raft usually.As a kind of size is 105 * 105 * 3 zirconium white small raft, just can be paved with a load bearing board of now using size 320 * 320 * 12, and the thickness of zirconium white backing plate reach 3mm with 9 small rafts.The zirconium white amount of Xiao Haoing is big like this, makes trouble, uses also inconvenient.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of load bearing board of zirconia, can reduce zirconic usage quantity, convenient simultaneously the use.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of load bearing board of zirconia is characterized in that: plate body is a lamination layer structure, comprises the sandwich setter plate layer and the zirconium white composite bed that is sprayed on sandwich setter plate layer upper surface of bottom.
As a kind of preferred, described sandwich setter plate layer skin is alumina layer, and internal layer is a silicon carbide layer.Can improve the work-ing life of load bearing board.
As a kind of preferred, described zirconium white composite bed thickness is 0.3-0.5mm.Can save zirconic usage quantity, and result of use is good.
As a kind of preferred, evenly be doped with nano particle in the described zirconium white composite bed.To improve the performance of sprayed coating.
Adopt technique scheme, saved the zirconium white resource, cost is low, and is easy to use, and the life-span is long.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a kind of load bearing board of zirconia structural representation of the present invention.
Embodiment
As Fig. 1, be a kind of load bearing board of zirconia of the present invention, its plate body is a lamination layer structure, comprises the sandwich setter plate layer 1 and the zirconium white composite bed 2 that is sprayed on sandwich setter plate layer 1 upper surface of bottom.Wherein Pen Tu zirconium white composite bed thickness is 0.3-0.5mm, and evenly is doped with nano particle.Described sandwich setter plate layer skin is alumina layer 11, and internal layer is a silicon carbide layer 12, and internal layer is closed by skin.
