What is Ferric Oxide CAS 1309-37-1?
Iron oxide (1309-37-1), as a multifunctional inorganic compound, has its application extended from traditional building materials to the field of nanotechnology. When making a choice, please note:
Industrial grade: Purity (≥99%) and heavy metal content are given priority.
Nanometer level: Focus on particle size distribution (such as 20-50 nm) and surface modification processes.
Performance advantages:
Strong ultraviolet absorption and high transparency (Hungman coefficient 6-7);
Improved heat resistance (resistant to 300℃ after coating process);
High catalytic efficiency (1 to 10 times higher than that of ordinary iron oxide).
Preparation process:
Sol-gel method, chemical precipitation method (with particle size controlled ≤50 nm).
Ferric Oxide CAS 1309-37-1 Use
Pigment industry: Coloring of paints, coatings, rubber and plastics (ranking second among inorganic pigments), high covering power, lightfastness (7-8 grades), weather resistance (4-5 grades)
Building materials: cement products, colored tiles, floor coloring, alkali resistance, low cost, color stability
Electronic materials: Magnetic recording materials (γ-Fe₂O₃), ferrite components, superparamagnetism, high specific surface area
Cosmetics: Sunscreen products, makeup (nano level), non-toxic, strong ultraviolet absorption, high transparency
Catalysis and Medicine: Catalyst carriers, biosensors, drug carriers, nanoscale particle size (20-50 nm), high surface activity
Ferric Oxide CAS 1309-37-1 safety
Toxicity
The International Agency for Research on Cancer (IARC) has classified it as a Group 3 carcinogen (not classified as carcinogenic to humans).
It is allowed to be used As a food colorant (E172), but heavy metals (As≤5 ppm, Pb≤20 ppm) need to be controlled.
Exposure limit
OSHA: TWA 10 mg/m³; NIOSH: IDLH 2500 mg/m³.
Storage requirements
Seal and avoid light, moisture and high temperature. Keep away from acids and alkalis.
