Description
Известны высокоомные сопротивлени , получаемые путем нанесени методом распылени на изолирующее основание тонкого провод щего сло на основе окиси олова с добавкой окиси сурьмы.High resistances are known that are obtained by spraying a thin conductive layer based on tin oxide with the addition of antimony oxide on the insulating base.
Предлагаемое сопротивление отличаетс от известных тем, что со ,держание окиси сурьмы составл ет 1% вес. и дополнительно введена окись цинка в количестве 5-8% вес.The proposed resistance differs from that known in that with, the retention of antimony oxide is 1% by weight. and additionally introduced zinc oxide in the amount of 5-8% weight.
Такое выполнение сопротивлени позвол ет получить пленки, обладающие высоким удельным сопротивлением при низком температурном коэффициенте и высокой стабильностью в интервале температур -60 -+250.Such an embodiment of the resistance allows to obtain films with high specific resistance with a low temperature coefficient and high stability in the temperature range of -60 - + 250.
Согласно предлагаемому способу пленки нанос тс на предварительно нагретые штабики из тугоплавкого бесщелочного стекла методом пульверизации. Стекло нагреваетс до 750°; врем обработки пленкообразующим раствором составл ет 20 сек.According to the proposed method, films are deposited onto preheated rods of refractory alkali free glass by sputtering. The glass is heated to 750 °; the processing time of the film-forming solution is 20 seconds.
Удельное поверхностное сопротивление пленок, полученных таким способом, колеблетс от 10 до 2000 ом. Пленки с удельным поверхностным сопротивлением от 10 до 300 ом имеют температурный коэффициент сопротивлени (ТКС) меньще 1,5.10-4 а пленки с сопротивлением 400-2000 ом имеют ТКС меньще 6,0.10-4 Пленки стабильны в интервале температур от -60 до +250° (изменение сопротивлени при температуре 250° в течение 50 час не превыщает ±1%).The surface resistivity of the films obtained in this way ranges from 10 to 2000 ohms. Films with specific surface resistance from 10 to 300 ohms have a temperature coefficient of resistance (TKS) less than 1.5.10-4 and films with a resistance of 400-2000 ohms have TKS less than 6.0.10-4 Films are stable in the temperature range from -60 to +250 ° (change of resistance at a temperature of 250 ° for 50 hours does not exceed ± 1%).
