Iranian Nanotechnology Firm Uses Silica to Make Special Casting Powder

‘Mavad Gostar Roham’ company used silica nanoparticles in its special casting powder to improve the fluidity of slurry so that it can cover the entire surface of the wax sample well and take and maintain the elegance and precision of the sample’s dimensions.

Also, it prevents the sedimentation of slurry until the end of the plaster’s drying, which, as a result, maintains the better integrity of the plaster mold.

The slurry dries in such a way that it can be used by people who make metal artifacts without a machine in addition to those who work in equipped casting workshops. On the other hand, application of silica particles with nano dimensions leads to better integrity and higher resistance in the gypsum mold in thermal tensions.

Among the advantages of the product are high strength against the thermal tensions of melting without cracking and breaking, high quality approved by gold and jewelry casting workshops, and cost-effectiveness compared to foreign samples.

Iran currently ranks 4th in the world in production of nano-science. This comes as a part of Iran's Nanotechnology Initiative Council’s first development plan, which has sought to advance nano-science in the country.

The second 10-year plan, which started in 2015, seeks to move nano-science from paper to the industry. In the meantime, the Nanotechnology Initiative Council is working on a third plan to trade Iranian nano-products in the global market.
