Used in the atomic energy industry and national defense:neutron moderator is in the graphite which has the performance of high melting point, stability,corrosion resistance,that's why graphite is widely used in these industry.but used in the atomic reactor,the purity of graphite is requested much higher,impurity content should not be more than dozens of PPM,especially boron is should be less than 0.5ppm.in the national defense industry,the graphite material is made be graphite products like the missile nose cones,the navigation equipment parts,Heat insulation material and the ray material etc.
Compared with atomic adsorption,the graphite furnace has advantages as following:
1、To much chemical element,the detection range of the graphite furnace is to be one over one billion.
2、Using improved equipments,to minimize obstacles;
3、By through atomic absorption of matrix,the graphite furnace can detect most of the known chemical elements.
As top graphite supplier of China National Nuclear Corporation,XRD Graphite Manufacturing Co.,Ltd is working hard to research deep-processing graphite products and surpass to be the advanced world level.
