然而’當使用上述⑴所揭露之方法將板狀破璃進行熱處理而 製造結晶化玻璃物品時,由於板狀玻璃中不含核形成劑,所以, 結晶會從板狀玻璃的表面、背面及端面向内部析出並且成長。因 此例如尽度大約1〇馳的板狀結晶化玻璃物品,其中心部分沒 有被結晶化,並且殘留厚度大約4mm的玻璃母體,而這些玻璃母 體部分會發生龜裂的情形。 一 以下,這種狀態可藉由圖式作進一步的說明,圖3係顯示上 述板,玻璃經由熱處理所得到之結晶化玻璃物品的斷面圖。‘在圖3 中,符號100表示結晶化玻璃物品,11〇表示結晶化玻璃體, 表示未結晶化的結晶性玻璃母體,130表示龜裂。如圖3所示,結 晶從板狀玻璃的表面、背面以及端面向内部成長,在已結晶化之 結晶化玻璃體110所包圍的區域(板狀玻璃物品的中心部)内存 在有未結晶化之結晶性玻璃母體12〇,而在這些結晶性玻璃母體 120内會發生龜裂13〇。 因此’對於經由上述(1)所揭露之製造方法而得到的結晶化玻 ,物品100而言’雖然從外觀上觀察不出龜裂13〇,但由於内部確 貫存在有龜裂130,所以會導致強度的不足。 另一方面,當使用上述(2)所揭露之集積法製造結晶化玻璃物 品,將結晶性破璃小體集積於耐火性模型内時,空氣會被密封在 結晶性玻璃小體間的空隙内。因此,所製造之結晶化玻璃物品的 内部容易產生氣泡。為了對結晶化玻璃物品的表面進行精細處理 而加以研磨時,這些氣泡容易在表面產生半圓形狀的氣孔缺陷。However, when the crystallized glass article is produced by heat-treating the plate-shaped glass by the method disclosed in the above (1), since the plate-like glass does not contain a core forming agent, the crystallizes from the surface, the back surface and the end of the plate glass. Develop and grow internally. Therefore, for example, a plate-like crystallized glass article having a fullness of about 1 pacing has no central portion to be crystallized, and a glass matrix having a thickness of about 4 mm remains, and the glass matrix portion is cracked. Hereinafter, this state can be further illustrated by the drawings, and Fig. 3 is a cross-sectional view showing the crystallized glass article obtained by heat treatment of the above-mentioned plate. In Fig. 3, reference numeral 100 denotes a crystallized glass article, 11A denotes a crystallized glass body, and a crystallized glass precursor which is not crystallized, and 130 denotes a crack. As shown in Fig. 3, the crystal grows from the front surface, the back surface, and the end surface of the sheet glass, and there is uncrystallized in the region surrounded by the crystallized crystallized glass body 110 (the center portion of the sheet glass article). The crystallized glass precursor 12 〇, and cracks 13 会 occur in the crystallized glass precursor 120. Therefore, in the case of the crystallized glass obtained by the production method disclosed in the above (1), the article 100 does not have cracks 13 外观 from the appearance, but since there is a crack 130 in the interior, Lead to insufficient strength. On the other hand, when the crystallized glass article is produced by the accumulation method disclosed in the above (2), when the crystallized glass body is accumulated in the fire resistance model, the air is sealed in the space between the crystallized glass bodies. . Therefore, bubbles are easily generated inside the crystallized glass article to be produced. In order to polish the surface of the crystallized glass article by grinding, these bubbles easily cause a semicircular pore defect on the surface.
