Abstract
The sintering aid for preparing the garnet-based transparent ceramic fluorescent material comprises ethyl orthosilicate and magnesium oxide, wherein the ethyl orthosilicate with the silicon oxide content of not less than 28.4 percent accounts for 0.3-0.7 wt% of the garnet-based transparent ceramic fluorescent powder raw material, and the magnesium oxide with the purity of not less than 99.9 percent accounts for 0.01-0.8 wt% of the garnet-based transparent ceramic fluorescent powder raw material. The garnet matrix transparent ceramic fluorescent material prepared by adopting the sintering aid has a compact microstructure and uniform grain size distribution.
Description
Technical field
The present invention relates to garnet-base transparent ceramic, particularly a kind of sintering aid and using method thereof that is used to prepare the garnet-base transparent ceramic fluorescent material.
Background technology
Fluorescent material transformant photodiode (being designated hereinafter simply as LED) is the mainstream technology route of commercial white light LEDs instantly, and its specific implementation form is mixed the white light emission that realizes for excite Ce:YAG fluorescent material by the GaInN blue-ray LED after.Because this kind white light LEDs the time is normally sneaked into Ce:YAG fluorescent material in Resins, epoxy or the silica gel in encapsulation, and the heat dispersion of these two kinds of organic packaged materials is all relatively poor and aging easily, and light decay is serious in time to make the device luminous efficiency.In recent years, the crystalline ceramics fluorescent material uses organic packaged material owing to avoiding or reduce, thereby can weaken the light decay effect to a great extent, may reform the packaging process of LED simultaneously.
As everyone knows, the acquisition of High-quality transparent pottery is the coefficient results of factor such as selection, blank forming technology and sintering temperature system of micro/nano-scale powder preparing technology, sintering aid.Wherein, the vital role of additive highlights more, and suitable additive is to the formation of liquid phase sintering, the purification of crystal grain lattice, and even grain size distributes and the control of microstructure of ceramics etc. often all has decisive role.
Be tetraethoxy (TEOS) for the most normal sintering aid that uses of garnet-base transparent ceramic material, its effect is to form a small amount of liquid phase with acceleration of sintering in sintering process.Yet we find only to use TEOS to be difficult to obtain microstructure densification, uniform high quality garnet-base transparent ceramic fluorescent material as sintering aid.Though this is because the use of TEOS can form liquid phase sintering, but being difficult to evenly control even grain size distributes, be difficult to suppress growing up unusually of some crystal grain in the sintering process, thereby the microstructure inequality that causes prepared stupalith is enclosed with pore etc. in the crystal grain inside of growing up unusually.
Summary of the invention
The object of the present invention is to provide a kind of sintering aid and using method thereof that is used to prepare garnet matrix crystalline ceramics fluorescent material, the use of this sintering aid helps obtaining microstructure densification, even, has the garnet matrix crystalline ceramics fluorescent material of high optical quality.
Technical solution of the present invention is as follows:
A kind of sintering aid that is used to prepare garnet matrix crystalline ceramics fluorescent material, its characteristics are that the concrete component of this sintering aid is tetraethoxy and magnesium oxide, described magnesian purity is not less than 99.9%, the content of reduced silicon oxide is not less than 28.4% in the solution of described tetraethoxy, described magnesian consumption is 0.01%～0.8wt% of garnet matrix crystalline ceramics fluorescent powder material, and the consumption of described tetraethoxy is 0.3～0.7wt% of garnet matrix crystalline ceramics fluorescent powder raw material.
The using method of this sintering aid is to add silica content to be not less than tetraethoxy 0.3wt%～0.7wt% of 28.4% in the garnet matrix crystalline ceramics fluorescent powder raw material that configures, add purity simultaneously and be not less than magnesium oxide 0.01%～0.8wt% of 99.9%, with powder mixing, refinement, powder oven dry is after granulation, compressing tablet through means such as ball millings; The back imposes the above cold isostatic pressure of 200MPa to it and is pressed into base substrate, and organic composition is removed in pre-burning again; Put into the general technology flow process of crystalline ceramics preparations such as vacuum or hot-pressed sintering furnace sintering at last, obtain high-quality garnet-base transparent ceramic fluorescent material.
Technique effect of the present invention:
Experiment shows, sintering aid among the present invention can play the effect that forms liquid phase sintering and evenly control grain size distribution to the garnet-base transparent ceramic fluorescent material simultaneously in sintering process, be to obtain microstructure densification, evenly, and the crystalline ceramics fluorescent material with high optical quality provides favourable condition.
