Since the temperature is as high as 200°C, the heat treatment time for crystallization is long, and there is a problem that only ceramics can be used for parts 10 and 4 that use molds and the like. A composition patent (Japanese Patent Publication No. 53-39884) was proposed to solve this drawback. However, these composition patents describe the fluidity of the glass body during softening and sintering, but the bending of the crystallized glass after heat treatment xho. 'r.

Ｏが最ち効果があることが分かった。Conventionally, the bending workability of crystallized glass has not been studied. Therefore, as a result of various studies on components that would improve the bending properties of crystallized glass obtained by softening and sintering a coarse-grained glass body, that is, allowing bending at lower temperatures, we found that MgO, ZnO. BaO. MH in SrO
It was found that O was the most effective.
次に本発明の製法について以下に述べる。上述の組成と

で３０分〜６時間保持し，結晶化ガラスを得た。Next, the manufacturing method of the present invention will be described below. The above-mentioned composition was prepared using raw materials such as oxides, carbonates, and sulfates, and depending on the amount of glass required, it was melted in a crucible, tank, or kiln at a temperature of 1400-1580°C, and then cooled. rear,
This glass was heated to 900 to 1100°C and held at this temperature for 30 minutes to 6 hours to obtain crystallized glass.
本発明に於で上記の如く組成を限定した理由は以下の通
りである。The reason for limiting the composition as described above in the present invention is as follows.
Ｓ１０２が６８％以上の時はガラスの粘度が高くなるｔ
，：めガラス流出時の温度が高くなり成形が困難となり
、４８％以下の時は結晶化ガラスのｉ．ｔ候性が悪くな
り、いずれも好ましくない。When S102 is 68% or more, the viscosity of the glass becomes high.
,: The temperature when the glass flows out becomes high, making it difficult to form, and when the temperature is below 48%, the i. Both are unfavorable because the weatherability deteriorates.
Ｃ，３０が２１％以上の時は結晶成長速度が大きくなり
軟化焼結が困難となり、６％以下では結晶の析出飛が少
なくなり、いずれも好ましくない。When C,30 is 21% or more, the crystal growth rate increases and softening and sintering becomes difficult, and when C,30 is less than 6%, precipitation of crystals decreases, both of which are unfavorable.
Ｒ，＋Ｏ（ＮａｚＯ＋ Ｋ２ｏ）が２２％以上では耐候
性が悪く沁り、５％以下ではガラスの粘性が高くなりガ
ラスが得られ難《なるので、各れ６好ましくない。If R, +O (NazO + K2o) is 22% or more, the weather resistance will be poor and the glass will be stained, and if it is less than 5%, the viscosity of the glass will become high and it will be difficult to obtain glass, so each of them is not preferred.
Ａｌ２０．が０，５％以下では耐候性を向上ずるのに不

ラスが得られ難くなり、同時に結晶化速度も違くなるの
で、各れも好ましくない。Al20. If it is less than 0.5%, it is insufficient to improve the weather resistance, and if it is more than 17%, the viscosity of the glass increases, making it difficult to obtain glass, and at the same time, the crystallization rate will also differ, so each is preferable. do not have.

ると耐水性が悪くなるので好ましくない。820m. ZnO. BaO. MgO is effective in reducing the viscosity of the glass phase of crystallized glass and lowering the temperature during bending.6 However,
, B,0, is 6% or more and ZnO is 10% or more -L, the amount of crystal precipitation decreases, and BaO content of 10% or more is undesirable because water resistance deteriorates.
