The importance of platinum thimble in thermocouple applications and features

Today the use of platinum in glass industry is very important, because the platinum only is wetting to glass, metal to improve its used in direct contact with the service life of the components of the molten glass platinum.

in this article, we discuss a platinum alloy, Known as hardening of the platinum) Specially developed for molten glass with thermocouple temperature measurement. Casing is made from special platinum alloy containing 10% rh, a small percentage of zirconium oxide or yttrium oxide ( As the particle stabilizers) , specially developed for the application of glass industry. 。 These materials provide significantly improved the performance of the conventional platinum and its alloys. It is a kind of new materials, and has set up a special optimize it.

应用：

高强度，在高温范围（ As much as 1700 & deg; C) Have good ductility.

良好的焊接能力，同时保持强度。

卓越的耐腐蚀性和更长的使用寿命下的更稳定的微观结构次。

重结晶少

这些特性允许更长的使用寿命单个组件和允许珍贵金属，例如，更经济地使用通过减小的壁厚。 The higher the strength of the material also has stable effect on the equipment manufactured by it. Strengthen the e. G。 In ceramics or refractory metal molybdenum, therefore become redundancy effectively. Fine contains dispersed zirconia as dispersoid to prevent grain growth to just below the temperature of the melting point. Due to improvements, finer microstructure, it is not sensitive to fairly along the grain boundary corrosion process than similar materials. This ensures a better corrosion resistance.
