結晶化ガラスが記載されている。[Conventional technology] Conventionally, crystallized glass has been used to take advantage of its excellent properties.
It is often used as an exterior and interior material for buildings in place of natural stones such as marble, but with the diversification of buildings in recent years, there is a need for diversification of building materials as well. One direction of such diversification is the diversification of color tones, and in the case of crystallized glass, a method of adding colored oxides to glass raw materials to color them in various tones has been developed, such as the invention of the present applicant. Special Public Service 1986
No. 49145 describes crystallized glass colored using the above-mentioned colored oxide.
［発明が解決しようとする問題点］

いう問題を有している。However, it is very difficult to obtain such a color tone with conventional crystallized glass, and the
Even in No. 49145, only a deep green (dark green) color tone can be obtained, and the actual situation is that it does not meet the needs of consumers. Moreover, the above-mentioned crystallized glass has a problem in that it is insufficient in chemical durability and mechanical strength required as a building material.

である。[Means for Solving the Problems] The present inventors have conducted various studies to solve the above problems, and as a result, they have developed gahnite (ZnO.Al2) as the main crystal.

It has been discovered that a light green color tone can be obtained by placing it on an appropriate stand, and this is proposed as the present invention.

［作用］
本発明は、旧イオンを固溶しうるガーナイトを主結晶と
して析出する。Ｎｉイオンはガラスマトリックス相中で
カッ色を呈する為、結晶化前の原ガラスはカッ色を呈す
るが、これを結晶化熱処理してガーナイトを主結晶とし
て析出させると、Ｎｉイオンの多くがガーナイトに固溶
されるために、結晶化ガラスはライトグリーンの色調を
呈する。[Function] In the present invention, gahnite that can dissolve old ions is precipitated as a main crystal. Since Ni ions exhibit a brown color in the glass matrix phase, the raw glass before crystallization exhibits a brown color, but when this is subjected to crystallization heat treatment to precipitate gahnite as the main crystal, most of the Ni ions become gahnite. Because it is a solid solution, crystallized glass exhibits a light green color.
また異種結晶、例えばフォルステライト（２Ｍｇｏ・Ｓ
ＮｉＯ゜）は結晶化ガラスに白色の色調を与え、この白
色がガーナイトに固溶されたＮｌイオンの色調より強い
ために、フォルステライトが結晶化ガラス中に少しでも
析出すると色調がぼやけたり、あるいはかき消されて白
色になってしまうおそれがある。それゆえ結晶化ガラス
がライトグリーンの色調を？するためには、ガーナイト
以外の異種結晶を析出させないことが必要である。Also, foreign crystals such as forsterite (2Mgo・S
NiO゜) gives crystallized glass a white tone, and this white color is stronger than the color tone of Nl ions dissolved in gahnite, so if even a small amount of forsterite precipitates in crystallized glass, the color tone may become blurred or There is a risk that it will be drowned out and become white. Is that why crystallized glass has a light green tone? In order to achieve this, it is necessary to prevent the precipitation of foreign crystals other than gahnite.
本発明のライトグリーンの色調を呈する結晶化ガラスの
主結晶であるガーナイトは高い機械的強度を有する。ま
たガーナイトは構成成分に５ＩＯ３を含まないために、
相対的にガラスマトリックス相中に５ＩＯ３が多量含有
される。このため得られる結晶化ガラスは機械的強度及
び化学耐久性に優れている。Gahnite, which is the main crystal of the light green-colored crystallized glass of the present invention, has high mechanical strength. Also, since Garnite does not contain 5IO3 as a constituent,
A relatively large amount of 5IO3 is contained in the glass matrix phase. Therefore, the obtained crystallized glass has excellent mechanical strength and chemical durability.
次に本発明のライトグリーンの色調を呈する結晶化ガラ
スの組成範囲を完配のように限定した理由を示す。Next, the reason why the composition range of the crystallized glass exhibiting a light green color tone of the present invention is completely limited will be explained.
５ＩＯ３は化学耐久性を高める成分であり、その含有量
は４０〜６０％である。ＳＩＯ□が４０％より少ないと
耐候性が著しく悪くなり、６０％より多いとガラス溶融
が困難になる。5IO3 is a component that increases chemical durability, and its content is 40 to 60%. If SIO□ is less than 40%, weather resistance will be extremely poor, and if it is more than 60%, glass melting will become difficult.
Ａｌ２Ｏ３はガーナイトの構成成分であり、その含を量
は１４〜２５％である。Ａｌ２Ｏ３が１４％より少ない
と結晶化しにくくなり、２５％より多いとガラスの溶融
性が悪くなる。Al2O3 is a constituent of gahnite, and its content is 14 to 25%. If Al2O3 is less than 14%, it will be difficult to crystallize, and if it is more than 25%, the meltability of the glass will be poor.
ＺｎＯとＭｇＯは合量で４〜１５％含有する。ＭｇＯと
ＺｎＯの合量が４％より少ないと結晶化しにくくなり、
１５％より多いと結晶化物の表面光沢がなくなる。また
ＺｎＯとＭｇＯはその割合がＺｎＯ／ＭｇＯ≧１となる
ように含有する。これはガーナイトの構成成分であるＺ
ｎＯをＭｇＯより多量含有させることでガーナイトを主
結晶として析出させるためである。ZnO and MgO are contained in a total amount of 4 to 15%. If the total amount of MgO and ZnO is less than 4%, it will be difficult to crystallize,
If it exceeds 15%, the surface gloss of the crystallized product will be lost. Further, ZnO and MgO are contained so that the ratio thereof is ZnO/MgO≧1. This is Z, which is a constituent of gahnite.
This is because by containing nO in a larger amount than MgO, gahnite is precipitated as the main crystal.
それゆえＺｎＯ／ＭｇＯ＜ １となればフォルステライ
トが主結晶として析出し、結晶化ガラスの機械的強度や
化学耐久性が不十分となり、またライトグリーンの色調
を早さない。なおＭｇＯは分相防止のために少量含有す
ることが好ましい。Therefore, if ZnO/MgO<1, forsterite will precipitate as the main crystal, the mechanical strength and chemical durability of the crystallized glass will be insufficient, and the light green color tone will not change quickly. Note that it is preferable to contain a small amount of MgO in order to prevent phase separation.
ＺｒＯ２とＴｌＯ２は核成形剤として合量で２〜１２％

出する。ZrO2 and TlO2 are 2 to 12% in total as nucleating agents.
include When the total amount of Zr09 and TlO2 is less than 2%, nucleation is insufficient, and when it is more than 12%, devitrification becomes significant. Also, the ratio of ZrO3 and TlO2 is ZrO3
/T1o2≧1. This is ZrO2
is mainly ROAl. This is because it acts to precipitate 03 (R is an alkaline earth metal) crystal, and is suitable for precipitating Garnai (ZnO, Al2O3), which is the main crystal of the present invention. TlO3 causes cloudiness that precipitates crystals such as forsterite, so Zr09/TlO2<
1, these undesirable crystals will precipitate as main crystals.
なおＴｊＯ□は失透と分相の防止のために少量含有する
ことが好ましい。Note that it is preferable to contain a small amount of TjO□ in order to prevent devitrification and phase separation.
Ｂ２Ｏ３の含有量は２〜１５％である。Ｂ２Ｏ３が２％
より少ないとガラスの溶融性が悪くなり、１５％より多
いと結晶化を阻害する。The content of B2O3 is 2-15%. B2O3 is 2%
If it is less than 15%, the melting properties of the glass will deteriorate, and if it is more than 15%, crystallization will be inhibited.
Ｎａ２Ｏの含有量は０．５〜１５％である。Ｎａ２Ｏが
０．５％より少ないとガラスの溶融性が劣り、１５％よ
り多いと耐候性が悪くなる。The content of Na2O is 0.5-15%. If Na2O is less than 0.5%, the meltability of the glass will be poor, and if it is more than 15%, the weather resistance will be poor.
Ｌ２Ｏの含有量は０．５〜８％である。Ｌ２Ｏが０．５
％より少ないとガラスの溶融性が劣り、８％より多いと
結晶化しにくくなる。The content of L2O is 0.5-8%. L2O is 0.5
If it is less than 8%, the meltability of the glass will be poor, and if it is more than 8%, it will be difficult to crystallize.
Ｌｉ２Ｏは溶融性を高めるために０〜５％含有する。Li2O is contained in an amount of 0 to 5% to improve meltability.
ＣａＯとＢａＯの含有量はそれぞれ０〜４％である。The contents of CaO and BaO are each 0 to 4%.
ＣａＯ及びＢａＯがそれぞれ４％より多いと結晶化しに
くくなる。If CaO and BaO are each more than 4%, crystallization becomes difficult.
Ａｓ２Ｏ３とＳｂ２Ｏ３は清澄剤としてそれぞれ０〜１

、２．８％より多いと失透が著しくなる。NIO is a colored oxide that gives crystallized glass a light green tone, and its content ranges from 0.005 to 2.8%.
It is. If NiO is less than 0.005%, it will not be possible to give the crystallized glass a sufficient light green tone, and if it is more than 2.8%, devitrification will become significant.
