          Iron Oxide

          Red

          Specification

          Iron content(indicated by Fe2O at 105oC baking ≥ 95%

          Volatile matter at 105oC≤1.0%

          Matter soluble in water≤0.3%

          Water extraction liquid acidity & allkality ≤20 ml

          PH value of water suspension 5-7

          Residue on sieve(63μm)≤0.3%

          Total calcium content(indicated by CaO)  0.3%

          Oil absorption (g/100g)15-25

          Existance of organic tinting matter Negative

          Colour comparison(contrast with standard Speciment) almost-micro

          Comparison of relative tinting strenghth (contrast with standard specimen) 95

          Water soluble chloride and sulfate (indicated by CL- and SO4-) ≤0.2%

          Lead chromate Negative

          Notes: 1) The standard specimen for relative tinting strength of the colour should be decided through the negotiation between the plant and customer two sides.

          2) In case of the sample colour shade, the test sample is fresher than which of the standard, the grade of colour difference is “slight”, now the product should be of the first class.

          Usage: pigment used in paint,rubber,plastic,buiding,cement,ceramic,etc.

          Packing: In plastic lined plastic woven bag of  25kg. net each.
