    • A method of producing a higher-purity glass element capable of attaining the higher-purity of a glass element while restricting the deformation thereof high-dimensionally; and a high- purity glass element. A method of producing a glass tube capable of obtaining a high-purity glass tube and a device therefore. The method of producing a higher-purity glass element comprising applying a voltage to a glass pipe (11) in an almost radical direction of the glass pipe (11) from electrodes (1, 2) in contact with the glass pipe (11) while the glass pipe (11) is being heated to temperatures less than 1300°C. The method of producing a glass tube comprises applying a voltage to the inner peripheral side and the outer peripheral side of a glass tube (106) to generate a voltage gradient in the radical direction of the glass tube (106) when a glass rod (103) is heated and softened, and a drilling jig (130) is brought into contact with the softened area of the glass rod (103) to thereby gradually form the glass rod (103) into the glass tube (106).
    • 制造能够获得玻璃元件的高纯度同时限制其高度变形的高纯度玻璃元件的方法; 和高纯度玻璃元件。 因此,能够得到高纯度玻璃管的玻璃管的制造方法和装置。 一种高纯度玻璃元件的制造方法,其特征在于,包括从与玻璃管(11)接触的电极(1,2)向玻璃管(11)的玻璃管(11)的大致自由方向施加电压,同时 玻璃管(11)被加热到低于1300℃的温度。 制造玻璃管的方法包括向玻璃管(106)的内周侧和外周侧施加电压,以在玻璃管(103)处产生玻璃管(106)的自由基方向的电压梯度 )被加热软化,钻孔夹具(130)与玻璃棒(103)的软化区域接触,从而逐渐将玻璃棒(103)形成玻璃管(106)。
