What is Calcined Rutile Sand CAS 1317-80-2?

It is a natural rutile mineral concentrate composed mainly of titanium dioxide, TiO2, and supplied as an industrial welding-grade sand. The calcined material is brown to black or reddish-brown, chemically stable, and used where high rutile content is required.

Why is calcination important for welding-grade rutile sand?

Calcination removes chemically bound water, organic matter, and volatile impurities that could otherwise contribute to weld defects. It also helps stabilize the rutile crystal structure, which supports more consistent arc behavior and reduces the risk of hydrogen-induced cracking.

How is this rutile sand used in welding electrodes?

It is used as a primary coating ingredient in rutile-type electrodes such as E6013, where it improves arc stability, slag formation, and slag detachability. The controlled particle size and low sulfur and phosphorus levels help produce cleaner, more reliable welds.

What are the key welding-grade specifications for this product?

The product typically contains at least 95.0% TiO2, with sulfur not more than 0.01%, phosphorus not more than 0.02%, Fe2O3 not more than 1.5%, and moisture not more than 0.05%. It is commonly supplied in mesh ranges such as 60-120 or 80-150 and can be customized.

Can it be used in pharmaceutical or food-grade titanium dioxide production?

No. This is an industrial mineral concentrate intended for welding, metallurgy, ceramics, glass, and pigment feedstock applications. It contains naturally occurring mineral impurities and should not be treated as a purified pharmaceutical or food-grade titanium dioxide.

Product Description

Calcined Rutile Sand CAS 1317-80-2 is a natural rutile mineral concentrate composed mainly of titanium dioxide, TiO₂, with EINECS 215-282-2.

Synonyms: Calcined Rutile Concentrate; Natural Rutile Sand; Titanium Dioxide Ore; High-Grade Rutile Flour; Calcined Titanium Ore.

CAS: 1317-80-2.

Molecular formula: TiO₂.

The calcined material is brown to black or reddish-brown, chemically stable, and used where high rutile content is required.

Calcination removes chemically bound water, organic matter and volatile impurities that could otherwise contribute to weld defects.

It also stabilizes the rutile crystal structure, supporting consistent arc behavior and reducing the risk of hydrogen-induced cracking.

It is used as a primary coating ingredient in rutile-type electrodes such as E6013, improving arc stability, slag formation and slag detachability.

It also serves as feedstock for the chloride process to produce titanium dioxide pigments, and for glass, ceramics and metallurgy.

The typical TiO₂ content is about 95.0% or higher, with sulfur not more than 0.01% and phosphorus not more than 0.02%.

The iron oxide (Fe₂O₃) content is typically not more than 1.5%, and moisture not more than 0.05%.

It is commonly supplied in mesh ranges such as 60-120 or 80-150 and can be customized.

Store in a dry, covered warehouse to prevent moisture pickup, and keep away from strong mineral acids.

Protect from moisture and keep containers closed when not in use.

Confirm appearance, TiO₂ content, sulfur, phosphorus, Fe₂O₃, moisture, particle size and grade as required.

Use suitable eye and skin protection during handling, and wash skin contact with soap and water.

Confirm packaging with the requested quantity and destination requirements.
