〈産業上の利用分野)
本発明は、天然石のメノウからつくられるオニキスと称
される黒色石の代替品となる黒色結晶化ガラス組成に関
するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a black crystallized glass composition that is a substitute for black stone called onyx, which is made from the natural stone agate.
(従来の技術)
従来から、オニキスと称される天然石のメノウからつく

ヤモンド、・ルビー等の天然石と同様に装飾品用の材料
として非常に需要の高いものであった。(Prior art) Black stones made from agate, a natural stone known as onyx (hereinafter referred to as natural stone oikis), have been in great demand as materials for decorative items, similar to natural stones such as diamonds and rubies. It was expensive.
ところが、天然石オニキスは天然石のメツ「りに炭素粒

出形態から加工製品の輸出形態への変化に伴い原石供給
の安定性に欠けてきたという問題もあった。However, natural stone onyx contains carbon grains (such as furfural, which is the raw material for nylon 66).
After impregnating the carbon particles, the carbon particles are steam-baked at 300 to 400°C to be colored black.The dyeing process to impregnate the carbon particles takes several months, and it takes a long time to obtain the final processed product. It required a long period of time. In addition, natural onyx has low heat resistance and many variations in quality, so cracks occur during the steaming process, resulting in a very low yield.
Also, due to its low heat resistance, it cannot be baked at temperatures above 500° C., making it impossible to perform secondary processing such as full printing. Furthermore, the majority of natural agate rough stones are imported from overseas such as Brazil, and with the shift from exporting rough stones to exporting processed products, there has been a problem that the supply of rough stones has become less stable. .

のである。(Problems to be Solved by the Invention) The present invention solves the above-mentioned conventional problems and provides a black crystallized glass that can be used as a decorative material equivalent to natural stone onyx, and can be produced into a final processed product in a short period of time. It is possible to obtain high-quality materials with little variation in quality (and has excellent heat resistance, resulting in a very high molding yield; furthermore, secondary processing such as full printing is possible, and material It was completed with the aim of creating a black crystallized glass composition that would be a substitute for natural onyx and ensure a stable supply.

.. The reason why the Al2O3 content was set at 0%7 is because the meltability deteriorates when it is out of this range, and the reason why the Al2O3 content was set at 3.0% to 8.0% is because if it is less than 3.0%, the tendency to devitrify increases. This is because if it exceeds 0%, the main crystals become beta-spodumene-based, making it impossible to obtain the desired black color. Li2O 7
.. If P2O5 is set to 0 to 13.0% and P2O5 is set to 0.7 to 2.5%, these will act as nucleating agents and crystal components for glass crystallization, and if it is outside the above range, it will not be sufficient. This is because crystallization cannot be achieved. Incidentally, the glass crystallization process is as shown in a later example, but by using these nucleating agents, lithium disilicate (Li
20.2Si02) can be precipitated to ensure strength and hardness. The reason for setting K2O to 0.5 to 3.5% is that if it is less than 0.5%, the melting temperature will be high (3.5%
This is because if it exceeds this amount, there is a risk that the glass will be deformed during the heat treatment process of crystallization.

It is possible to obtain black crystallized glass having a color tone equivalent to that of natural onyx by blocking the visible light range. Also,
