Bibliography

Describes methods for the chemical analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5% to 45% of ZrO[2]) and raw materials, using traditional ("wet") methods, inductively coupled plasma atomic emission (ICP-AE) spectrometry and flame atomic absorption (FAA) spectrometry. Covers apparatus, reagents and dissolution methods.
