X-ray fluorescence and specific gravity

X-ray fluorescence testing was performed at Boral Resources (Taylorsville, GA) by fusing ignited ash with a flux. To remove organics and volatile materials from the sample, samples were ignited in a muffle furnace to 950°C for two hours before infusing with a fusion matrix and testing. Then the samples were exposed to x-rays, and the fluorescence allowed for the measurement of the relative percentage of the inorganic constituents (e.g., calcium, magnesium, iron, and silica). Specific gravity of ash was tested using a helium pycnometer.X射线荧光（X-ray fluorescence, XRF）测试于位于佐治亚州泰勒斯维尔的Boral Resources公司开展，测试采用将灼烧灰分与熔剂熔融的方法。为去除样品中的有机物与挥发性物质，所有样品先置于马弗炉中以950℃灼烧2小时，随后加入熔融基质完成熔融后开展测试。待样品经X射线辐照后，通过其产生的荧光信号可测定各类无机成分（如钙、镁、铁、二氧化硅）的相对百分比含量。灰分的比重则采用氦比重瓶（helium pycnometer）进行检测。
