Typical Chemical Analysis


Expert Reviews

Dr. Bruce Perrault, Ph.D (Georgia Institute of Technology (Georgia Tech), USA)

A thin layer of Barium Sulfate Nanoparticles called baryta is first coated on the base surface of most photographic to increase the reflectiveness. The light-sensitive silver halide emulsion is then coated over the baryta layer. The baryta coating limits the penetration of the emulsion into the fibers of the paper and makes the emulsion more even, resulting in more uniform blacks. More recently, baryta has been used to brighten papers intended for ink-jet printing.

Dr. Myron Rubenstein, Ph.D (Polytechnic University of Turin, Italy)

The majority of synthetic Barium Sulfate Nanoparticles used as a component of white pigment for paints. In oil paint, barium sulfate is almost transparent, and is used as a filler or to modify consistency. One major manufacturer of artists’ oil paint sells “permanent white” that contains a mixture of titanium white pigment (TiO2) and barium sulfate. The combination of barium sulfate and zinc sulfide (ZnS) is the inorganic pigment called lithopone. In photography it is used as a coating for certain photographic papers.

Dr. Huojin Chan (University of Science and Technology of China, Hefei, Anhui, China)

Barium Sulfate Nanoparticles used in soil testing. Tests for soil pH and other qualities of soil use colored indicators, and small particles (usually clay) from the soil can cloud the test mixture and make it hard to see the color of the indicator. Barium sulfate added to the mixture binds with these particles, making them heavier so they fall to the bottom, leaving a clearer solution.

Dr. Ms. Yi Yen Shi (King Mongkut’s University of Technology Thonburi,Bangkok, Thailand)

Barium Sulfate Nanoparticles the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. As barium sulfate has high burning point and is insoluble in water, it is used as a coating material in casting of copper anode plates. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating material on the mold surface. Thus when the liquid copper solidifies in form of an anode plate it can be easily released from its mold.
