Addition Li described in step (2)2CO3Speed of agitator be 30~50 turns/min, after adding continue stir 45min.
Lithium ion adsorbent described in step (2) is porous silica or basic zirconium chloride, the use of lithium ion adsorbent
Measure as TiO2The 0.8~1.0% of quality.
Calcining drying condition described in step (3) is：Started to warm up by room temperature, be warming up to constant temperature 1h after 400~500 DEG C,
It is continuously heating to constant temperature 6h after 650~700 DEG C.
Soak time described in step (4) is 6~8h.
Tritium of the present invention breeds the ceramic material preparation method of metatitanic acid lithium, comprises the following steps that：
(1) preparation of titanium source presoma：
Metatitanic acid before salt treatment after sulfuric acid process removal of impurities is beaten, makes its TiO2Content in 300~400g/L, will
The 400g/L prepared in advance sal volatile is uniformly added in meta-titanium acid solution, in the addition and metatitanic acid of ammonium carbonate

Turn/min, be slowly added to, to make the sulfuric acid that metatitanic acid is mingled with fully be reacted with ammonium carbonate, addition is finished, continue to stir 30min
Afterwards, sheet frame squeezing is carried out, filtrate carries out condensing crystallizing, obtains ammonium sulfate product, filter cake enters next process.
(2) lithium source is inlayed reaction and adulterated with iontophoresis：
Preceding process filter cake is subjected to mashing processing using ionized water, TiO is formulated into2Concentration is 550~600g/L, control
Li2CO3/H2TiO3Mol ratio be 1.1~1.3：1 is fully beaten, and speed of agitator is 30~50 turns/min, stirs 45min
Afterwards, appropriate porous silica or basic zirconium chloride progress ion doping is added, continues to stir after 30min, sheet frame squeezing, filter
Liquid instead arrives preceding process and used as the solution for preparing ammonium carbonate, and filter cake enters subsequent processing.
(3) calcining and micro mist：
The filter cake of previous process is fitted into high purity quartz pallet, calcining drying is carried out, it is desirable to risen by room temperature, 400
~500 DEG C of constant temperature are continuously heating to after 650~700 DEG C after 1 hour, and constant temperature stops heating, cool the temperature to room temperature after 6 hours
Afterwards, after being crushed using super fine machine, tritium propagation ceramic material metatitanic acid lithium is obtained.
(4) post-process：
In order to reduce the influence of minimal residue lithium, the metatitanic acid lithium prepared is soaked 6~8 in the ionized water boiled
After hour, drying obtains tritium propagation ceramic material metatitanic acid lithium final products.
Li2TiO3Purity, granular size, particle diameter distribution of powder etc. all can be to Li2TiO3The preparation of ceramic bead and bead
Production tritium performance has a huge impact, so higher requirement is proposed to metatitanic acid lithium, to meet the metatitanic acid subsequently prepared
Lithium propagation ceramic performance is superior.
The present invention is during metatitanic acid lithium is prepared, and, particle diameter big to intensity is small, impurity is few, open-celled structure is abundant emphatically
Metatitanic acid lithium prepare studied.With the titanium partially of the activity in wide material sources, cheap sulfuric acid method titanium pigment production process
Acid is as titanium source, after ammonium carbonate is handled, and adds lithium carbonate, realizes that atom or the embedding lithium salts of molecular level level are reacted, instead
Appropriate iontophoresis doping is carried out after answering again, to improve performance of the metatitanic acid lithium in propagation ceramics.Because LiOH fusing point
Compare Li2CO3Fusing point it is low, so as to promote particle to become big during reaction, influence the performance of particle, thus lithium salts we select
Lithium carbonate is selected, while lithium carbonate is during reaction, more micro-channel holes are provided for metatitanic acid lithium, is follow-up inclined
Lithium titanate propagation ceramics create more open-celled structures, and there is provided more excellent performance.Calcination process strict temperature control
In 650~700 DEG C of temperature province, to ensure the particle for the Large ratio surface to form loose shape, specific surface energy is enough in 50m2/ g with
The particle of upper anatase titanium dioxide, because the grain graininess of rutile-type is hard and density is high, propagation ceramic performance reduction, and with relatively low
The anatase titanium dioxide particle of density is advantageously in the preparation of propagation ceramics.In order to reduce the influence of the lithium remained in micropore, it will make
After standby obtained metatitanic acid lithium crude product is soaked 6~8 hours in the ionized water boiled, drying obtains tritium propagation ceramic material and used
Metatitanic acid lithium final products.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, flow of the present invention is short, technique is simple, scientific and reasonable, low production cost, production process are easily controllable, product matter
Amount is stable.
2nd, the metatitanic acid lithium intensity of the invention prepared is big, particle diameter is small, impurity is few, open-celled structure is abundant.
