摘要: An infrared detective element for detecting a dose of infrared rays by a change in electrical resistance of monofilaments composed mainly of silicon carbide upon infrared radiation thereto,
either the monofilaments having a resistivity of 1.0 x 10⁵ to 1.0 x 10³ Ω·cm at room temperature and a diameter of 3 to 200 µm,
or the monofilaments having a composition:
Si: 50 to 70 wt%
C: 28 to 40 wt%
O: 0 to 10 wt%
the balance (H and/or Ti or Zr): 0 to 10 wt%, and having a resistivity of 1.0 x 10⁵ to 1.0 x 10⁻¹ Ω·cm at room temperature and a diameter of 3 to 200 µm,
in either case, the monofilaments being arranged between electrodes without bringing them into contact with each other. The infrared detective elements of the present invention are excellent in properties, especially short response times.摘要翻译: 一种红外线检测元件,用于通过在红外辐射时主要由碳化硅组成的单丝的电阻变化来检测红外线的剂量,单丝的电阻率为1.0×10 5至1.0×10 3欧米茄 室温下的直径为3〜200μm的单丝或Si:50〜70重量%的单丝C:28〜40重量%O:0〜10重量%余量(H和/或 Ti或Zr):0〜10重量%,在室温下电阻率为1.0×10 5〜1.0×10 -3Ω·cm,直径3〜200μm, 情况下,单丝布置在电极之间,而不使它们彼此接触。 本发明的红外线检测元件的特性优异,反应时间短。
