China Chemical Reference Standards Factory – Certificate of Certified Reference Material Ash fusibility – Shandong Institute of Metallurgical Science
This certified reference material is made from carefully selected raw coal. The coal was air dried, reduced in size to <0.2mm and ignited at 815℃ to constant mass and homogenized, then packaged in to individual bottled units. The homogeneity test was done on the bottled units by determination of the sulfur in ash and FT under the reducing atmosphere. The minimum mass of sample taken for analysis is 0.05g(sulfur) and about 0.15g(FT). Variance analysis showed that the variability among dif...
