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.
