Description
Technical field
The present invention is to provide a kind of preparation methods of light porous aluminum phosphate-alumina titanate ceramics ball, belong to special cermacis
Technical field of material.
Background technology
Porous alumionphosphate（AlPO4）- aluminium titanates（Al2TiO5) Ceramic Balls being widely used in the industrial production be general, it can
Using as catalyst carrier, chemical filler, heat preservation and refractory material etc..It is urged as carrier of photocatalyst and other liquid phase reactors
Agent carrier and as in water during the adsorbent of noxious material, in order to ensure with efficient catalytic effect and（Or）Absorption
Efficiency often requires that porous ceramic ball in water in suspended state, this just needs to prepare a kind of light porous ceramic ball.Mesh
Before, it is mainly then removed both at home and abroad using " core " of the sphere made of the organic matter lost as spherical green body is easily burnt by firing
Spherical organic " core " is removed, so as to prepare a kind of suspensible porous ceramics hollow ball.The disadvantages of this method is：Molding is more difficult,
And during organic matter burns and loses, easily lead to ceramics cracking or destroy, reduce the yield rate of product；In addition, this technique mistake
Journey is more complicated, and cost is higher, deficiency in economic performance, environment easy to pollute.In order to overcome above-mentioned problem, invention provides a kind of high
Effect, the preparation method of simple, safe and reliable, easily operated, low-cost light porous aluminum phosphate-alumina titanate ceramics ball.
Invention content
The technology of the present invention provides a kind of efficient, simple, safe and reliable, easily operated, low-cost light porous phosphoric acid
The preparation method of aluminium-alumina titanate ceramics ball, technical solution are：
A kind of preparation method of light porous aluminum phosphate-alumina titanate ceramics ball, it is characterised in that using following steps：（1）
Aluminum titanate powder, alumina powder, biphosphate aluminium powder, frit powder is 2 according to mass ratio：1：3.11：0.03 ratio
Example carries out dry-mixed；Wherein, the silica containing 50 wt% lithias, the sodium oxide molybdena of 30 wt% and 20 wt% in frit；（2）Add
Adding the poly-vinyl alcohol solution of a concentration of 8 wt%, the additive amount of binding agent is the 5% of blank gross mass as binding agent；Then it makes
Grain, molding, are made cylindric green body；（3）After 70 DEG C of dry base substrates 5 hours, it is for semicircle spherical that green body is put into interior bottom
In alumina crucible, 150 DEG C are heated to the speed of 5 DEG C/min under air atmosphere and keep the temperature 2 hours, then with 10-
The speed of 20 DEG C/min heats to 380 DEG C and keeps the temperature 1 hour, is then heated to the speed of 1 DEG C/min
680 DEG C and 2 hours are kept the temperature, finally heat to 1100 DEG C with the speed of 5 DEG C/min and keeps the temperature 2 hours, it is then natural
Room temperature is cooled to, obtains light porous aluminum phosphate-alumina titanate ceramics ball.
A kind of preparation method of the light porous aluminum phosphate-alumina titanate ceramics ball, it is characterised in that：Step（1）In
Aluminum titanate powder and oxide powder average grain diameter all for 0.6 micron, aluminium dihydrogen phosphate powder average particle size is 0.5 micron,
The average grain diameter of frit powder is 0.7 micron.
A kind of preparation method of the light porous aluminum phosphate-alumina titanate ceramics ball, it is characterised in that：Step（2）In
Molding refer to powder carry out dry-pressing formed, briquetting pressure 10-25MPa.
Fig. 1 is the photo that light porous aluminum phosphate-alumina titanate ceramics ball prepared by the technology of the present invention floats on the water surface；From
It can see in figure：Aluminum phosphate-alumina titanate ceramics ball is floated in water, illustrates that the volume of aluminum phosphate-alumina titanate ceramics ball is close
Degree is less than the density of water, i.e., the material that prepared by the technology of the present invention belongs to light porous ceramic material.
The principle of this technology invention is as follows：
It is fusible at a lower temperature for liquid using aluminium dihydrogen phosphate, the then property of solidifiable again at relatively high temperatures
It can so that green body is spontaneously formed in sintering process as sphere, and concrete principle is as follows：Aluminium dihydrogen phosphate be heated to 150 DEG C,
After heat preservation 2 hours, aluminium dihydrogen phosphate is changed into as liquid, is then heated rapidly to 380 DEG C and keeps the temperature 1 hour, the purpose is to make
Various raw materials form a kind of very big viscous body of viscosity at such a temperature.The effect for adding in frit is on the one hand can to promote raw material
Melt the viscous body very big for a kind of viscosity, on the other hand can also increase surface tension so that viscous physical efficiency spontaneously form for
Sphere.It is heated slowly to during 680 DEG C, aluminium dihydrogen phosphate is gradually solidified as solid；In temperature-rise period, aluminium dihydrogen phosphate meeting
Aluminum phosphate, vapor and phosphoric acid are decomposed into, the phosphoric acid of generation can be reacted with magnesium carbonate generates aluminum phosphate-aluminium titanates, and vapor
There is pore-forming with carbon dioxide etc., can thus prepare light porous aluminum phosphate-alumina titanate ceramics.
