Data for: Vitrification of environmentally harmful by-products from biomass torrefaction process

Spectroscopy in the mid-infrared range: 4000 - 400 cm-1 was carried out using a Brucker 70V Fourier spectrometer. The samples were prepared in the form of KBr pellets. Measurements were made by the transmission technique, and the spectra were recorded on the scale of absorbance at 256 scans and 4 cm-1 resolution. XRD tests were conducted using the powder method on an X'Pert Pro diffractometer from Philips. A measurement step of 0.008°and count time of 50 s were used. Phase identification was performed based on data from the ICDD PDF-4 database. High-temperature microscopy was carried out using a Misura 3.232 hot stage microscope.

中红外波段（4000~400 cm⁻¹）的光谱测试采用布鲁克（Brucker）70V型傅里叶变换光谱仪（Fourier spectrometer）完成。样品以溴化钾压片（KBr pellets）形式制备，测试采用透射法（transmission technique），以吸光度（absorbance）为标尺记录光谱，扫描次数为256次，光谱分辨率为4 cm⁻¹。X射线衍射（XRD）测试采用粉末法（powder method），在飞利浦（Philips）X'Pert Pro型X射线衍射仪上开展，设置测量步长为0.008°，计数时长为50 s。物相鉴定（phase identification）基于国际衍射数据中心（International Centre for Diffraction Data, ICDD）PDF-4数据库的数据完成。高温显微观测（high-temperature microscopy）采用Misura 3.232型热台显微镜（hot stage microscope）进行。
