Abstract

The invention discloses a hydrogen sensor for a high-pressure hydrothermal system and a making method thereof. The hydrogen sensor comprises a base, a conical pad, a conical sleeve, an electrolyte ceramic and an insulating ceramic, wherein the base is of a cylinder structure, a cylindrical hole and a conical hole which are parallel and symmetrical are formed in the base, the big-end-up bottom of the conical hole is connected with the cylindrical hole, the bottom of the conical hole is provided with the conical pad, the upper portion of the conical hole is provided with the conical sleeve, an electrolyte ceramic assembly and an insulating ceramic assembly are arranged in the conical sleeve, an insulating tube is arranged in the cylindrical hole and is tightly in contact with the conical pad, an electrode lead is connected between the top face of the electrolyte ceramic assembly and the top face of the insulating ceramic assembly, an electrode lead is introduced out of the bottom face ofthe electrolyte ceramic assembly and the bottom face of the insulating ceramic assembly, and the electrode leads penetrate through the conical pad and the insulating tube to be connected to a measurement instrument. The hydrogen sensor has good sealing performance, corrosion resistance and high-temperature mechanical strength, is simple in structure, quick to respond, stable and reliable and produces a very good effect.

Description

technical field [0001] The invention relates to a hydrogen sensor, in particular to a hydrogen sensor used in a high-pressure hydrothermal system and a manufacturing method thereof, belonging to the technical field of sensor equipment. Background technique [0002] Since it was discovered in 1979 that high-temperature hydrothermal fluids were ejected from the submarine chimneys at 21°N (EPR) on the Eastern Pacific Rise, in order to better constrain the evolution of system chemistry and time, it has become particularly important to obtain true and reliable in-situ data through technical means . For almost all geochemical systems, hydrogen fugacity (activity) is generally considered to be one of the most important variables because it controls the direction and extent of mass transfer reactions and the formation of secondary alteration minerals. [0003] At present, a variety of hydrogen sensors have been developed, but none of them can perform in-situ measurement under high ...
