Title: Abhijit S Gurav: Innovator in TiO₂ Pigment Production

Introduction

Abhijit S Gurav is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of pigment production, particularly through his innovative methods for creating titanium dioxide (TiO₂) pigments.

Latest Patents

Gurav holds a patent for the "Formation of TiO₂ pigment by spray calcination." This method involves suspending a TiO₂-based precursor in a liquid, which may or may not include fuel additives. The suspension is then sprayed to form droplets that are transported into a flow reactor with a carrier gas. These droplets are decomposed at high temperatures to produce TiO₂ pigment particles, which are collected downstream. In a preferred embodiment, a colloidal suspension of an insoluble TiO(SO₄)ₓ(OH)ᵧ precipitate, along with suitable fuel additives, is spray-calcined at temperatures ranging from 900°C to 1200°C to yield pigment-quality TiO₂. The resulting TiO₂ pigment particles have a primary size between 150-250 nm and exhibit minimal aggregation.
