ASTM E367-09

Standard Test Methods for Chemical Analysis of Ferroniobium

SIGNIFICANCE AND USE
These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications such as Specification A550. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
SCOPE
1.1 These test methods cover the chemical analysis of ferroniobium having chemical compositions within the following limits:
  ElementConcentration, % Aluminum2.00 max  Carbon0.30 max  Chromium2.00 max  Cobalt0.25 max  Lead0.01 max  Manganese3.00 max  Niobium40.00 to 75.00  Phosphorus0.05 max  Silicon4.00 max  Sulfur0.03 max  Tantalum7.00 max  Tin0.15 max  Titanium5.00 max  Tungsten0.50 max
1.2 The test methods appear in the following order:
Sections Separation of Niobium, Tantalum, and Titanium
by the Ion-Exchange Test Method10-16  Titanium by the Photometric Test Method [0.05 % to 5.0 %]17-21  Niobium by the Gravimetric Test Method [40 % to 75 %]22-23  Tantalum by the Gravimetric Test Method [1 % to 7 %]24-25  Tantalum by the Photometric Test Method [0.25 % to 1 %]26-30
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6, and specific warning statements in 11.1.  
10.1 These test methods cover the determination of niobium, tantalum, and titanium in ferroniobium from 40 % to 75 %, 0.25 % to 7 %, and 0.05 % to 5.0 %, respectively.
