It is characterized in that SrO is used as a main component instead of aO, and a small amount of MgO is contained in order to facilitate melting of glass.

が得られる。Since MgO also has the effect of lowering the melting temperature of glass, the glass raw material containing MgO in the present invention can be melted under ordinary glass melting conditions of 1400 to 1700 ° C., and monoclinic celsian crystals and / or cordiers can be used. A low-expansion, heat-resistant crystallized glass in which light crystals are deposited can be obtained.
【００１５】結晶化ガラスの組成範囲を上記のように限
定した理由を以下に述べる。ＳｒＯは１４％未満でも４
５％超でも単斜晶のセルシアンが析出しなくなり、本発
明の目的とする結晶化ガラスが得られない。The reason why the composition range of the crystallized glass is limited as described above will be described below. SrO is less than 14% 4
Even if it exceeds 5%, monoclinic celsian does not precipitate and the crystallized glass aimed at by the present invention cannot be obtained.

ｌ2 Ｏ4 などの結晶が析出するようになる。３５％超で
は、ガラスの熔融温度が高くなり、１７００℃以下の温
度での熔融が困難になる。When Al 2 O 3 is less than 10%, monoclinic celsian does not precipitate, and instead SrA having a low melting point is used.
Crystals such as l 2 O 4 will be deposited. If it exceeds 35%, the melting temperature of glass becomes high, and it becomes difficult to melt at a temperature of 1700 ° C. or less.
【００１７】ＳｉＯ2 は３７％未満では単斜晶のセルシ
アンもコージェライト結晶も析出しにくくなり、６２％
超では１７００℃以下の温度での熔融が困難になる。When SiO 2 is less than 37%, it becomes difficult to precipitate monoclinic celsian and cordierite crystals.
If it exceeds the above value, melting at a temperature of 1700 ° C. or less becomes difficult.
【００１８】ＭｇＯは、１７００℃以下の温度でガラス
を熔融するためには必要な成分であるが、１０％超では
単斜晶のセルシアンが主結晶ではなくなり、耐熱性が低
下し、熱膨張係数が大きくなる。０．１％未満ではガラ
スの熔融が困難になる。MgO is a necessary component for melting glass at a temperature of 1700 ° C. or lower, but if it exceeds 10%, monoclinic celsian is not the main crystal, the heat resistance is lowered, and the thermal expansion coefficient is increased. Grows larger. If it is less than 0.1%, it becomes difficult to melt the glass.
【００１９】ＳｒＯの一部をＢａＯに置換しても本発明
の目的は達せられるが、ＢａＯ／（ＳｒＯ＋ＢａＯ）の
重量比が０．５超では、主結晶が単斜晶セルシアンでは
なくバリウムオオスミライトなどが析出するようになる
ため、耐熱性が低下し好ましくない。Although the object of the present invention can be achieved by substituting a part of SrO with BaO, when the weight ratio of BaO / (SrO + BaO) exceeds 0.5, the main crystal is not monoclinic celsian but barium osumilite. And the like will be deposited, which lowers the heat resistance and is not preferable.
