请使用高级语法及词汇润色以下句子：It can be found that the sintering temperature to 800 ℃ the composite material also present in the XRD diffraction pattern of a weak Cr2AlC diffraction peak but with the increase of s

Upon analysis, it is discernible that when the sintering temperature reached 800 ℃, a faint Cr2AlC diffraction peak was detectable in the XRD diffraction pattern of the composite material. However, as the sintering temperature continued to escalate, the aforementioned peak was entirely absent, indicating that at 800 ℃, a fraction of the Cr2AlC remained undecomposed, but with the gradual surge in sintering temperature, complete decomposition was eventually achieved.
