Abstract
The invention discloses a method for preparing ceramics capable of repeatedly storing heat. The method is characterized in that titanium oxide black blue powder and pottery clay are weighed according to a weight percentage, raw materials are injected into a ball mill after being mixed, and are ground after water is added; well ground slurry subsides; supernatant liquid is pumped out after subsiding, precipitates are taken out to be placed on the clean ground to be dried in the sun; the dried soil is placed into a pugmill to be pugged, and the air in the soil is discharged. Well pugged mud is made into corresponding green bodies and is dried, and the dried green bodies are put into a fire ceramic body to be calcined, and a ceramic product which can repeatedly store heat can be obtained after natural cooling. The ceramic product capable of repeatedly storing heat is placed in an illumination position, titanium oxide can be converted into lambda-titanium oxide, can store heat, and is converted into beta-titanium oxide to release heat under definite conditions, then the beta-titanium oxide is converted into lambada-titanium oxide after the ceramic product is heated, and the ceramic product can continuous to absorb and store heat.
Description
Technical field
The present invention relates to a kind of can the preparation method of the pottery of heat accumulation repeatedly, belong to ceramic technology field.
Background technology
The researchist of Tokyo Univ Japan have developed a kind of type material that can store heat energy for a long time, and this material is called heat accumulation porcelain (heatstorageceramic) by them.This is that one can be used as solar heat power generation system or effectively utilize industrial exhaust heat, can make the heat accumulating of heat energy recycling, because this material just can discharge the heat energy of storage under weak pressure condition.
The material of heat accumulation can comprise brick or concrete, the heat of storage can be discharged lentamente, and other materials be as water or ethylene glycol, when they from solid-state convert liquid state to time can absorb heat.But neither one can heat energy storage for a long time in these materials because they can along with the time lentamente, release of heat naturally.Can long-time storage heat energy and in the time of specifying the material of release of heat, be a Gospel for field of renewable energy.
The research team that graduate school of Tokyo Univ Japan Ohkoshi teaches develops this heat accumulation porcelain (heatstorageceramic) that can store heat energy for a long time.This material, is called as strip λ five and is oxidized Tritanium/Trititanium, be only made up of titanium atom and Sauerstoffatom, can absorb and discharge a large amount of heat energy (230kJL-1).The thermal energy stored is very large, is equivalent to 70% phase-change accumulation energy with the water at fusing point.In addition, under weak pressure condition, 60MPa (megaPascal) just impels strip λ five to be oxidized Tritanium/Trititanium to be phase-changed into β five and to be oxidized Tritanium/Trititanium, discharge the heat of storage.Except direct heat application, heat also can be stored, and to pass through the electric current of material or to use light-struck mode, impels material repeatedly to absorb and release of heat by various method.
It is a kind of simple titanium oxide, the element that standing stock are abundant and very environmental protection that strip λ five is oxidized Tritanium/Trititanium.Current heat accumulation porcelain (heatstorageceramic) is expected to become the novel material applied in solar power system, and European countries are promoting its application energetically, and it effectively can also utilize industrial exhaust heat.This material can also be applied in advanced electronic device, as pressure-sensitive, and the heating cushion that can reuse, pressure sensitive conductive sensor, current drive-type resistive ram (ReRAM), and optical memory etc.The application of this technology on pottery yet there are no.
Summary of the invention
Problem to be solved by this invention be to provide a kind of can the preparation method of the pottery of heat accumulation repeatedly.
In order to solve the problem, the invention provides a kind of can the preparation method of the pottery of heat accumulation repeatedly, it is characterized in that, comprise the following steps:
Step 1): take 10 ~ 15% 5 oxidation Tritanium/Trititanium black blue powders by weight percentage, 85 ~ 90% potter's clay, inject ball mill after being mixed by raw material, carry out grinding after adding water, the material-mud fineness requiring grinding to go out is 300 ~ 500 orders;
Step 2): the material-mud of milled is precipitated; Extract supernatant liquid out after precipitation, and taken out by throw out and be placed on clean ground and dry, the time of drying is 60 ~ 90 days;
Step 3): the earth after drying is put into soil kneader and carries out mud refining, get rid of the air in mud simultaneously;
Step 4): the mud refined is made corresponding base substrate, and dries in the baking room of 80 ~ 100 DEG C;
Step 5): the base substrate after drying is put into firing ceramics base substrate, calcines 6 ~ 10 hours at 800 ~ 1250 DEG C, obtaining after naturally cooling can the ceramic of heat accumulation repeatedly.
This ceramic is placed on illumination place, five oxidation Tritanium/Trititaniums can change into λ-five and be oxidized Tritanium/Trititanium, can store heat, time in holding chamber, under weak press strip part, its structure will change, being transformed into " β-five is oxidized Tritanium/Trititanium " can release of heat, and then by ceramic after heating (80 ~ 100 DEG C), β-five is oxidized Tritanium/Trititanium and is converted into λ-five oxidation Tritanium/Trititanium, can continue to absorb and store heat.
