Scope

This standard specifies the chemical analysis methods for finished and semi-finished products of four types of gyromagnetic ferrite materials: bismuth calcium vanadium indium, yttrium calcium vanadium indium, yttrium aluminum and yttrium iron gallium in garnet type gyromagnetic ferrite materials. Some projects adopt instrumental analysis. Law. This standard applies to four types of garnet type gyromagnetic ferrite materials: bismuth calcium vanadium indium, yttrium calcium vanadium indium, yttrium aluminum and yttrium iron gallium, etc. Calcium (Ca), yttrium (Y) in finished and semi-finished products ) (or the total amount of rare earth elements), vanadium (V), iron (Fe), aluminum (A1), gallium (Ga), indium (In), bismuth (Bi) and impurity lead (Pb) element content. The preparation and calibration of standard solutions in this standard should comply with the provisions of GB 601 "Preparation of standard solutions for titration analysis of chemical reagents (volume analysis)".
