玻璃基体的成型方法
摘要：
一种玻璃基体的成型方法，其中，使至少模具表面具有导电性的旋转或轮转的成型模具的上述模具表面与具有一对主面且包含含有碱金属氧化物的玻璃材料的玻璃基体的上述主面中的一个主面接触，并且，一边在将上述玻璃基体的与上述模具表面接触的接触面保持在高于100℃且(Tg+50℃)以下(其中，Tg表示上述玻璃材料的玻璃化转变温度)的温度的状态下，对上述玻璃基体施加使上述接触面侧相对于相反的主面侧为高电压的直流电压，一边使上述成型模具旋转或轮转，同时使上述成型模具或上述玻璃基体沿与上述玻璃基体的接触面平行的方向按照上述成型模具的旋转或轮转速度进行移动，从而将上述玻璃基体的上述接触面成型。
摘要（英）：

A glass substrate molding method includes: preparing a rotatable or wheelable molding die having a die surface and contacting the die surface with one of a pair of principal surfaces of a glass substrate made of a glass material containing an alkali metal oxide, the die having conductivity; keeping the one of principal surfaces contacted with the die surface at a temperature over 100°C and equal to or lower than Tg + 50°C; applying direct-current voltage to the substrate to be higher voltage on the contacted one of principal surfaces than voltage on an opposite surface of the contacted one of principal surfaces; and rotating or wheeling the die and simultaneously moving the die or the substrate in a direction parallel to the contacted one of principal surfaces in conformity with rotation or wheeling speed of the die, to mold the contacted one of principal surfaces of the substrate.
