Blanc fixe, also known as permanent white, is a chemical compound that is widely used in various industries for its properties as a white pigment or filler material. The term blanc fixe originates from French, where "blanc" means white, and "fixe" refers to its stability and permanence.
Chemically, blanc fixe is composed of barium sulfate (BaSO4), a crystalline mineral that occurs naturally as the mineral barite. It is commonly found in the form of a fine, white powder. Blanc fixe possesses exceptional whiteness, opacity, and chemical stability, making it an ideal ingredient in many applications.
One of the key industries that extensively uses blanc fixe is the paint and coatings industry. It is added to paints, primers, and coatings to enhance their opacity, brightness, and reflectivity. Blanc fixe acts as an inert filler, strengthening the coating and preventing it from cracking or peeling. It is also utilized in paper manufacturing to increase the brightness and smoothness of the paper, improving its printability.
In addition to these applications, blanc fixe finds its use in the production of plastics, rubber, ceramics, adhesives, and even in the medical field for certain diagnostic procedures. Its ability to maintain its structural integrity, resistance to chemical reactions, and non-toxic nature contribute to its popularity and wide range of applications.
Overall, blanc fixe is a white pigment or filler material that provides exceptional whiteness, opacity, and stability in various industries, serving as a versatile and indispensable component in numerous products and processes.
