摘要： A crucible for preparing a single crystal which comprises an iridium-rhenium alloy comprised of from about 80 to about 99 parts of iridium and from about 1 to about 20 parts of rhenium. The crucible has excellent creep resistance and compatability properties and is especially useful for the preparation of gadolinium-gallium-garnet crystal.

摘要： A thick film thermocouple matching the performance of solid wire thermocouples and capable of operating at high temperatures with minimal drift is produced by (1) forming two powdered metal pastes of differing compositions, each including a frit which is substantially neutral with respect to the metal components of the respective paste and has essentially no effect upon the thermoelectric EMF, (2) applying the pastes to a surface to form a pair of thick film elements overlapping at one point which form a thermocouple upon firing, (3) firing the applied pastes, and (4) attaching leads to the fired elements and assembling the finished thermocouple. Optionally, the thermocouple elements or legs may be overglazed to protect them against damage to the metal films and to improve stability during continuous use at high temperatures.
摘要翻译：通过（1）形成两种不同组成的粉末状金属浆料，其中产生了相当于金属部件基本上为中性的玻璃料，产生了匹配实心线热电偶性能并且能够在高温下以最小漂移运行的厚膜热电偶并且对热电EMF基本上没有影响，（2）将糊剂施加到表面以形成一个在一点烧结时形成热电偶重叠的厚膜元件，（3）烧制所施加的糊料，和（4）将引线连接到烧制元件并组装完成的热电偶。任选地，热电偶元件或支脚可以被过釉，以保护它们免受金属膜的损伤，并提高在高温连续使用期间的稳定性。
