It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.
If you want to know the chemical?compound components, you can do the analysis of meteorological chromatography, and then testing, if you just want to detect contents of elements, you can do a XRF, but you should smash, grind and homogenize the refractory bricks. The specific operation process is not convenient to describe in detail, that is, X ray diffraction, through X ray fluorescence analysis, you can know that the elements and contents contained in it, if you want to understand its internal structure, you can also do a XRD
