14. TITANIUM SPONGE
•KMML has taken a big leap into aerospace working towards
value addition of its Titanium Tetra Chloride with the launch
of Titanium Sponge Plant
•Titanium Metal derived from Titanium Sponge finds use in a
variety of fields like aerospace industry, atomic energy,
defence etc
•Due to its lightweight, higher strength, non-corrosive and
non-reactive quality, it finds use in surgical and orthopaedic
transplants
•KMML’s foray into the
production of Titanium Sponge
makes it the first and only
company in India, and the
7
th
country in the world,
to produce Titanium Sponge

15. NANOTITANIUM DIOXIDE
•Nanomaterials - Particles with Dimension in the
range of 1-100 Nm
•The Average Density and Coordination between the
neighbors changes as Crystal Size is reduced, hence
properties of Nanomaterials differ from Parent
Material
•As Size Decreases the following properties increases
- Hardness & Strength of Metals and Alloys
- Electrical Conductivity in Ceramics and Magnetic
Nanocomposites
•Nanomaterials finds application mainly in
Nanoelectronics, Catalysis, Semiconductors,
Coatings, Ceramics Etc

16. NANOTITANIUM DIOXIDE – GLOBAL OVERVIEW
•Recently there has been a surge in Nano TiO2
products in the international arena
•The Global Production of Nanotitanium Dioxide
is Approximately 5000 Tonnes/Annum
•In India Currently 10-20 tonnes of
Nanotitanium Dioxide is Imported Annually
for Various Applications

22. •Particle Size
- Pigmentary TiO2: 250 - 350 NM
- Nano TiO2: 20 – 50 NM
•Pigmentary TiO2 - Scatter visible Light and
absorb UV light
Nano TiO2 - Scatter and reflect UV light
effectively and transmit Visible light through
the crystal

23. •Nanotitanium Dioxide have higher Surface Area and
high Photocatalytic Activity,
•Heavy Surface Coatings are required to suppress
the Photocatalytic Activity
•For Coating applications, Nanorutile is surface
coated with Silica, Alumina and Zirconia
•Nanoanatase has higher Photocatalytic Activity,
hence used in Self Cleaning Paints Etc

24. NANOTITANIUM DIOXIDE
APPLICATIONS OF NANORUTILES
•Paint Industry: Nano particles provide better UV
protection against chalking and fading when used in
coatings
•Metallic Coatings: Nanorutile mixed with Aluminium
flakes is used to impart Metallic Look in the
Automobile industry This is based on scattering of
visible light by nano TiO2 particles and Aluminum
flakes

25. NANOTITANIUM DIOXIDE
APPLICATIONS OF NANORUTILES
•Plastics: Nano titanium dioxide particles in
combination with polymers provide better UV
stability
•Cosmetic Industry: The UV scattering ability finds
extensive application in Sunscreen Cosmetics
•Wood Coatings: Nanorutiles provide better UV
shielding and hence lower wood yellowing when used
in wood coatings

SYNTHETIC ROUTES
The main commercial routes for manufacture of nano titanium
dioxide are
•Vapor phase synthesis from Titanium
Tetrachloride and Oxygen
•Thermal Hydrolysis From Titanium Oxy Chloride
And Titanyl Sulphate
•Hydrothermal Synthesis

NANO TIO2 AT KMML
•KMML R&D has developed a process for making
Nanotitanium Dioxide from Titanium Tetrachloride
•Indian Patent has been filed for the process developed
(application Number: 5789/Che/2010 Dated 5/3/10)
•The Process involves scrubbing of Titanium
Tetrachloride with water to make Titanium Oxy
Chloride and then precipitating Nano Tio2 from Oxy
chloride Solution at low temperature by Water
addition
•Thus precipitated Nano TiO2 is washed, filtered,
calcined and fluid jet milled to obtain the final product
