Description
(54) УСТРОЙСТВ041ЛЯ ИЗМЕРЕНИЯ ТЕМПЕРАТУРЫ РАСПЛАВА ПРЕИМУЩЕСТВЕННО В ТИГЛЕ(54) DEVICES FOR MEASURING THE MELTING TEMPERATURE MOSTLY IN THE TIGLE
1one
Изобретение относитс к области термометрии и может быть использовано дл контрол температуры расплава в уста новках дл выращивани монокристаллов.The invention relates to the field of thermometry and can be used to control the temperature of a melt in single crystal growth plants.
Известно устройство дл измерени температуры расплава преимущественно в тигле, содержащее двухэлектродный чувствительный элемент 1 .A device for measuring the temperature of a melt, preferably in a crucible, containing a two-electrode sensing element 1 is known.
Однако известное устройство не обеспечивает требуемой точности измерени , иэ-оа погрешности, обусловленной химическим взаимодействием чувствительного элемента с расплавом.However, the known device does not provide the required accuracy of measurement, and the error due to the chemical interaction of the sensitive element with the melt.
Наиболее близким к предлагаемому $юл етс устройство дл измерени температуры расплава преимущественно в т гле , содержащее двухэлектродный чувствительный элемент, электроды которого выполнены из материалов, обладающих различным парциальным давлением кислорода , а между электродами введен твердый электролит с кислородно-анионной проводимостью ,The closest to the proposed device for measuring the temperature of the melt is predominantly in gas, containing a two-electrode sensing element, the electrodes of which are made of materials having different oxygen partial pressure, and a solid electrolyte with oxygen-anionic conductivity is introduced between the electrodes
Однако известное устройство не обладает требуемой точностью измерени из-за погрешности, обусловленной разрушениект твердого электролита и электродов, помещенных в расплав.However, the known device does not have the required measurement accuracy due to the error caused by the destruction of the solid electrolyte and the electrodes placed in the melt.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
Указанна цель достигаетс тем, что. в качестве твердого электролита использован тигель, а одним из электродов служит This goal is achieved by the fact that. a crucible is used as a solid electrolyte, and one of the electrodes is
10 расплав, подключенный к вторичному прибору через лигатуру, а второй электрод выполнен в виде введенного в устройство подвижного контакта.10, the melt is connected to the secondary device through a ligature, and the second electrode is made in the form of a moving contact introduced into the device.
На чертеже схематически изображено The drawing schematically shows
15 предлагаемое устройство.15 proposed device.
Устройство содержит электрод 1, в качестве которого служит расплав, монокристалл 2, тигель 3, лигатура 4, вторичный прибор 5, второй электрод 6, вы10 в вцде подвижного контакта, держатель 7 подвижного контакта, платформа 8, индуктор 9, механизм 10 перемещени индуктор а.The device contains an electrode 1, which serves as a melt, a single crystal 2, a crucible 3, a ligature 4, a secondary device 5, a second electrode 6, in the vce of the movable contact, a movable contact holder 7, platform 8, inductor 9, movement mechanism 10 inductor a .
