Problem
Titanium-based nanocomposites can have non-uniform phase distribution, uncontrolled particle or crystallite size, inadequate porosity, agglomeration, high energy demand, lengthy processing, or scalability limitations.
Why it matters
A defined porous three-component material could support catalytic or environmental research, but target-specific performance, stability, leaching, reuse, and scalable manufacture require independent validation.
Approach
The patent forms a gel from calcium and magnesium salts, a titanium alkoxide, and a polyol, then dries and calcines it to produce carbon with CaTiO3 and MgTiO3 crystalline phases.
Who may benefit
Potential beneficiaries include titanate-material laboratories, catalyst and adsorbent researchers, environmental-remediation groups, specialty-ceramic manufacturers, and process developers studying multiphase porous powders.
Potential value
The disclosure connects two specified titanate phases and carbon with elemental ranges, heterogeneous particle and pore features, and a bounded gel, drying, and calcination process.
Background
Background
Titanium-oxide and titanate materials are investigated for catalysis, energy storage, and electronic or environmental applications. Single-phase and binary materials may not provide the desired combination of structural stability, porosity, and multifunctionality. Hydrothermal, sol-gel, and solid-state routes can also produce uneven phase distribution, uncontrolled size, inadequate pores, or high energy demand. The patent proposes a carbon-containing calcium-titanate/magnesium-titanate composite and defines its phase identity, elemental composition, crystallite size, morphology, pore fractions, and production sequence.
Technology overview
Technology overview
XRD identifies carbon, orthorhombic CaTiO3, and rhombohedral MgTiO3. Claim 1 specifies about 1–5 at.% C, 20–35 at.% Ti, 5–15 at.% Mg, and 5–15 at.% Ca. Calcium and magnesium salts are added to a titanium-compound solution in a polar protic solvent, and a polyol forms a gel. The gel is heated at about 100–200 °C to a dry powder and calcined at about 600–800 °C. The product includes spherical, flake-like, and agglomerated particles with heterogeneous pores.

Commercial opportunity
Commercial opportunity
The material may interest specialty-ceramic, catalyst, adsorbent, or environmental-technology developers. Commercial assessment should establish phase and pore reproducibility, batch consistency, contaminant-specific capacity or catalytic rates, stability and reuse, constituent leaching, treated-medium safety, scale-up of gel handling and calcination, energy consumption, product-form integration, and comparative cost.
