specific Embodiment approach 1

[0013] Specific embodiment one: a kind of Mo of the present embodiment The analysis method of carbon element in pure molybdenum is to carry out according to the following steps:

[0014] Step 1: Connect the carbon-sulfur analyzer for analyzing carbon by infrared absorption method to the power supply, and preheat for 2 to 4 hours;

[0015] Step 2: Burn the infrared ultra-low carbon sulfur crucible at 1000-1500°C for 20-30 minutes;

[0016] Step 3: Cool the crucible burned in Step 2 in a desiccator for 1 to 3 hours;

[0017] Step 4: After the preheating of the carbon-sulfur analyzer in step 1, weigh 0.2-0.5g of shavings Mo1 pure molybdenum, input the weight value, add 0.3-0.6g of iron filings and 0.3-0.6g of tungsten-tin flux ;

[0018] Step five: measure according to the analysis method of the instrument, and obtain the analysis result, that is, complete the analysis of the carbon element in Mo1 pure molybdenum.

[0019] This embodiment includes the following beneficial effe...

Abstract

An analysis method of carbon element in Mo1 pure molybdenum. The invention relates to the analysis method of carbon element in metal materials, and aims to solve technical problems of high deviation and low accurate degree in an analysis method of the carbon element in Mo1 pure molybdenum in the prior art. The analysis method includes following steps: (1) switching-on and pre-heating a carbon and sulfur analyzer for analyzing carbon elements through an infrared absorption method ; (2) burning an infrared ultralow carbon and sulfur crucible; (3) cooling the burned crucible in a dryer; (4) when the carbon and sulfur analyzer is pre-heated, weighing the Mo1 pure molybdenum, inputting weight values, and adding iron chip and a tungsten-tin flux; and (5) performing measurement according to the analytic methods of the instrument to obtain an analytic result, thereby completing the analysis of the carbon element in the Mo1 pure molybdenum. The analysis method is significantly reduced in deviation and is greatly increased in accuracy. The analysis method is applied in the field of analysis of the carbon element in metal materials.

Description

technical field [0001] The invention relates to a method for analyzing carbon elements in metal materials. Background technique [0002] Mo1 pure molybdenum (Mo1 is a grade of pure molybdenum) has high melting point, good thermal conductivity, small thermal expansion coefficient, low resistance, low evaporation pressure, high elastic modulus, and good heat resistance. But it has poor high temperature oxidation resistance and poor room temperature ductility. [0003] The analysis of carbon in Mo1 pure molybdenum is generally carried out by infrared absorption method, carbon-sulfur analyzer, ultra-low carbon sulfur crucible, and tungsten-tin flux. The chemical analysis results have large deviations and low accuracy. Contents of the invention [0004] The present invention aims to solve the technical problems of large deviation of analysis results and low accuracy in the existing analysis method for the carbon element in Mo1 pure molybdenum, thereby providing an analysis met...
