Problems solved by technology

Due to factors such as collisions during transportation, there are many small cracks in the crucible, which are difficult to find with the naked eye. When testing samples, due to the sharp rise in temperature, crucible cracks are common, often resulting in test failures and unstable test results. Phenomenon

Abstract

The invention belongs to the technical field of titanium sponge detection, and particularly relates to a method for detecting hydrogen, oxygen and nitrogen in titanium sponge. The invention solves the technical problem by providing the method for detecting hydrogen, oxygen and nitrogen in the titanium sponge, and the method has stable detection result. The method for detecting hydrogen, oxygen and nitrogen in the titanium sponge takes a graphite sleeve crucible as a sample container. As the invention takes the graphite sleeve crucible as the sample container for melting the titanium sponge for detection, the experiment failure caused by the damage of the sample container is effectively avoided, the detection efficiency is improved, and the detecting accuracy is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of sponge titanium detection, in particular to a method for detecting hydrogen, oxygen and nitrogen in sponge titanium. Background technique [0002] Nitrogen and oxygen in titanium sponge products are the two most important elements affecting the quality of titanium sponge. The detection of hydrogen, oxygen and nitrogen in titanium sponge is mainly carried out by nitrogen, hydrogen and oxygen analyzers at home and abroad. The method is to put the sponge titanium sample into the sample container, and then put the sample container in the nitrogen, hydrogen and oxygen analyzer for detection. Sponge titanium has a melting point of 1668°C and is a refractory metal. In order to completely melt and release nitrogen, hydrogen, and oxygen elements, a high-temperature graphite crucible is generally used as a container. Due to factors such as collisions during transportation, there are many small cracks in the crucib...
