Potassium titanate

Potassium titanate (CAS 12673-69-7), also known as potassium titanium oxide, is an inorganic ceramic compound produced in fibrous or whisker form for use as a functional filler and reinforcing agent.

It is primarily sourced for its flame retardancy and rheology modification properties across demanding industrial applications. In automotive and aerospace friction materials, these whiskers replace asbestos as a reinforcing filler.

The material is used in brake pads and clutch facings, improving thermal stability and wear resistance without hazardous fiber concerns. Plastics and polymer compounders incorporate it to enhance mechanical strength.

It provides fire resistance in engineering thermoplastics used in structural components. Building and construction applications include fire-retardant coatings and boards where the fibrous morphology contributes to flame suppression.

The compound also ensures dimensional stability under heat. In textile and paper processing, it functions as a functional additive in specialty coatings that require controlled rheology and improved surface durability.

Potassium titanate is supplied as a white powder or as short-fiber material, with fiber dimensions and aspect ratios specified to suit reinforcement applications. Technical grade is the standard commercial offering.

Purity and particle morphology are typically confirmed by supplier specification sheets. Bulk and packaged formats are available depending on downstream processing requirements for industrial manufacturing.
