Iranian Firm Makes Silica Powder by Utilizing Nanotechnology

‘Novin Fadak Sepahan’ company has made the silica nanoparticles with superficial nanometric porosity which are supplied in both A4 and A7 grades.

They benefit a uniform particles size distribution and high surface area, thereby being used as suitable additive for a wide variety of material systems.

Utilization of the nanotechnology synthesis method has created the possibility to produce nanoparticles with high surface area, superficial nanocavities and narrow particle size distribution.

They can be used for the nanopowder Grade A4 as reinforcement for the composite fabrication industries, additive for increasing the concentration of fluids, anti-blocking agent, additive for preventing the agglomeration of multiphase systems such as synthetic resins, agent for tailoring the rheology of industrial paints, appropriate alternative to bentonite in the industrial paints, and production of epoxy-based adhesives and sealants.

The product can also be utilized for the nanoparticles Grade A7 as anti-caking and anti-agglomeration agent, absorbent for liquids with 300 percent absorption capacity, drying agent in the production of granules and carrier in the production of powdery toxins.

Earlier this year, a nanotechnology company in Iran also succeeded in production of a new type of casting powder with a special formulation in which silica nanoparticles were used to improve performance and quality.

‘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.
