Description
Technical field
The present invention relates to a kind of material compositions, relate more particularly to a kind of ceramic substrate composition and be used for preparing purposes and the method for tangible family tree, belong to inorganic materials and applied technical field thereof.
Background technology
By giving birth to and being extremely the life course that all animals and the mankind must experience, especially for there are the mankind of senior emotion and thinking, remains setting is all very important " after one's death thing " since ancient times, this has just had many spectacular emperor's tombs in ancient times, the pyramid of such as ancient egypt, Chinese many of tremendous momentum emperor mounds are (as the Ming Dynasty Ming Tombs, The Eastern Tombs of the Qing Emperors, The Western Tombs of the Qing Emperors, Tang Zhaoling, and not yet by Qin Shihuang Tomb of excavating etc.), these are all the external embodiments thirsted for for a kind of demutation, and carry out holding a memorial ceremony for visiing as offspring descendants, the ground of giving expression to one's grief over sb.'s death.
And along with the progress of human civilization, and the transformation of idea, also progressive and change is had constantly for the funeral and interment form after death, such as in the city of China, be even popularized for rural area now, realized from the large burial in the ground form of floor space, after changing into cremation, bone ash is loaded the dramatic shift of cinerary casket, change so, brings many benefits, such as, take up an area sharply reducing of volume.
Exactly because also like this, how to preserve the remains of the dead, such as bone ash, nail, hair, tooth, clothing etc. also exist huge demand, therefore, there is a kind of sacrifice that there is variform and pattern, that be used for depositing above-mentioned remains at present or hold a memorial ceremony for and visit apparatus, be generally called " tangible family tree ".
Tangible family tree, has the cavity that some can hold above-mentioned article usually, thus can the above-mentioned remains of goner deposit in wherein, then tangible family tree can be placed on memorial tablet or in mourning hall, hold a memorial ceremony for visit and cherish the memory of for relatives.
But current tangible family tree, is generally wooden or plastics and makes, therefore there is many defects, such as occur as time goes by damaging by worms, be out of shape, aging, more because it can not resist high temperature, and fire often put by mourning hall, memorial tablet, therefore there is disaster hidden-trouble.
Although at present common cinerary casket, various informative, its maximum purposes is only used for laying up hone ash, and its shape is single, purpose clear and definite, thus it openly and legally is put and there is certain affective disorder, is also respectful to the relatives that die.
Therefore, how to develop and there is better quality, performance and do not hinder the tangible family tree of sight, still there is the demand proceeding to study.
All these, it is all the power place that the present invention is accomplished, the present invention is intended to develop a kind of novel ceramic substrate composition, its suitable screening by component and particular combination, it is made to can be used to prepare tangible family tree, there is good performance simultaneously, thus be with a wide range of applications and marketable value in field of funeral and interment, more can be used as the Emotion carrier that alive people cherish the memory of relatives, give expression to one's grief over sb.'s death.

performance test
Respectively the formed substrates that above-described embodiment and comparative example obtain is tested, measure folding strength and thermal stability respectively, respective
(1) mensuration of folding strength: measure according to the universal measurement method of folding strength, the results are shown in following table:
| Numbering | Folding strength (MPa) |
| JT1-JT3 | 155-158 |
| D1-D3 | 144-146 |
| D4-D6 | 140-143 |
| D7-D9 | 142-145 |

| D13-D15 | 119-124 |
| D16-D21 | 139-142 |
As seen from the above table, when aluminum oxide, sepiolite do not carry out modification; Metal-salt does not carry out process like this of the present invention, and when not adopting secondary temperature elevation to calcine and change temperature rise rate, folding strength all will be caused to have and significantly reduce.
Can find out simultaneously, after first low temperature calcination, high-temperature calcination can obtain best technique effect, do not experience low temperature calcination and directly adopt high-temperature calcination (see D13-D15) on the contrary effect reduce the most obvious, even want, significantly lower than directly adopting low temperature calcination, to demonstrate specific secondary clacining processing parameter of the present invention thus and there is beyond thought technique effect.
(2) in the mensuration of 300-700 DEG C of constant interval thermal expansion coefficient, the results are shown in following table:
| Numbering | Thermal expansivity (× 10 -6/℃) |
| JT1-JT3 | 3.83-3.94 |

| D13-D15 | 5.12-5.17 |
| D16-D21 | 4.56-4.63 |
As seen from the above table, when aluminum oxide, sepiolite do not carry out modification; Metal-salt does not carry out process like this of the present invention, and when not adopting secondary temperature elevation to calcine and change temperature rise rate, thermal expansivity all will be caused to have and significantly raise.
Can find out simultaneously, after first low temperature calcination, high-temperature calcination can obtain best thermal expansivity, when not experiencing high-temperature calcination (see D10-D12), thermal expansivity is maximum, demonstrates necessity and the unobviousness of high-temperature calcination after first low temperature calcination thus.
(3) mensuration of thermostability, under high temperature and low temperature, specifically carry out hydrothermal exchange (specifically through 200 DEG C of-20 DEG C of hydrothermal exchange 1 time), investigate matrix whether because of can not withstand temp sharply change and break, measure 100 samples of each embodiment and/or comparative example respectively, measurement is broken percentage, the results are shown in following table:
| Numbering | Break percentage (%) |
| JT1-JT3 | 0 |
| D1-D3 | 1 |
| D4-D6 | 1 |
| D7-D9 | 2 |
| D10-D12 | 3 |
| D13-D15 | 2 |
| D16-D21 | 2 |
As seen from the above table, when aluminum oxide, sepiolite do not carry out modification; Metal-salt does not carry out process like this of the present invention, and when not adopting secondary temperature elevation to calcine and change temperature rise rate, all thermostability is had remarkable reduction; Can also can find out, when composite metal salt does not carry out process like this of the present invention, rupture rate will be caused to have and significantly raise, this is non-obvious.
Can find out, when only carrying out low temperature calcination, the rupture rate of product is maximum simultaneously, may be now to sinter not, causes crystalline phase state labile wherein, can not stand the sharply change of temperature.Also find, when temperature rise rate changes to some extent, rupture rate also significantly raises simultaneously, demonstrates the temperature rise rate only having 40 DEG C/min thus optimum, even if increase to 50 DEG C/min or be reduced to 30 DEG C/min, thermostability also all will be caused significantly to reduce.
Comprehensively above-mentioned, when ceramic substrate composition of the present invention comprises base-material, modified nano-alumina particle, composite metal oxide powder, modified meerschaum micro mist, zinc sulfate, organic binder bond, composite metal salt powder, tourmalinite micro mist, magnesium borate crystal whisker and compounded mix, and when adopting suitable preparation technology parameter, the formed substrates with premium properties can be obtained, thus can on the basis of this formed substrates, through follow-up conventional processing, the tangible family tree with superperformance just can be obtained.
Should be appreciated that the purposes of these embodiments is only not intended to for illustration of the present invention limit the scope of the invention.In addition; also should understand; after having read technology contents of the present invention, those skilled in the art can make various change, amendment and/or modification to the present invention, and these all equivalent form of values fall within the protection domain that the application's appended claims limits equally.
