GB/T 21114-2019 (English Version) PDF

Scope: This standard specifies the chemical analysis methods for refractory materials and ceramics composed of oxides. Samples are prepared by melting and casting glass slices, and X-ray fluorescence spectroscopy (hereinafter referred to as XRF) is used for determination. This standard applies to the material types listed in Chapter 3, and other refractory material types can be used for reference. Note 1: When the content of these elements in the sample exceeds a certain amount, such as tin, uranium, zinc and zinc, there will be difficulties in melting. In this case, refer to the corresponding literature. Note 2: For mass fractions greater than 9956 (dry basis ) components, these values can also be verified by direct measurement if all existing trace components and loss on ignition have been determined and obtained by subtraction.
