Iranian Scientists Produce New Non-Toxic Pigment for Textile, Ceramic Industries

Tehran, Iran | Posted on March 29th, 2012

In association with the Institute for Color Science and Technology, Iranian researchers at Tarbiat Modarres University managed to produce hematite nano-capsule as a non-toxic red pigment to be used in textile and ceramic industries.

"Cadmium sulphoselenide-zirconium inclusion red pigments were produced as the commercial red color due to the extreme need of textile industries. However, cadmium sulphoselenide is very toxic and harmful. Results of international studies show that hematite is the best option. Therefore, our goal in this research was to synthesize hematite nano-capsule as a non-toxic ceramic pigment," Maryam Hosseini Zari, a member of the Scientific Board of Institute for Color Science and Technology, told the INIC.

Nano-capsule or inclusion red pigments are new generation of pigments. These pigments, also known as non-similar or occluded pigments, are formed by placing the known and unstable pigments in a bed of stable phases.

Dr. Hosseini explained how the nano-capsules were synthesized, and said, "We used co-precipitation synthesis method and also available industrial raw materials. We firstly determined the formulation and the weight, produced solutions containing the desirable ions with appropriate concentrations, and finally, we produced the precipitator solution. Next, the solution containing iron ion reacted with the precipitator solution within the solution containing silisium ion under the controlled temperature and other operational parameters. Mineralisers and additives play key role in the production of the product."

The complementary research was carried out in Modena University, Italy. The industrial test took place in INCO, one of the famous and credible companies in the field of ceramic paints.
