Alkoxide Hydrolysis Process:
This process can be classified into two methods depending on the type of Hydrolysis reactions.
In the first process ultra fine Titania powder can be prepared through hydrolysis of Titanium Isopropoxide, Butoxide or Ethoxide at about 25.C. The liquid Titanium Alkoxide solution is pressurized with Nitrogen gas and the entire solution is sprayed […]

Chloride Process:
The ilmenite or rutile ore is treated with coke and chlorine at a temperature of 950.C so as to form Titanium Chloride. The prepared Titanium Chloride is purified by distillation process. The distilled Titanium Chloride is oxidized with oxygen enriched air at a temperature of 1000.C. Rutile powder is formed as the final product.
The […]

High Purity Titania Powder can be prepared through the following methods.
1. Sulphate Process
2. Chloride Process
3. Alkoxide Process
4. Forced Hydrolysis Process
5. Laser Synthesis Process
Sulphate Process
The natural occuring ilmenite ore is first processed into usable form by the mineral processing route. The purified and processed ore is digested with sulphuric acid in a digester under […]

The extensive applications of Titania makes the material as an indispensable technical product in the industry. The major widely used applications are as follows

In the preparation of various capacitors and varistors in the electronic industries.
As an Opacifier in glazes and enamel frits
As white pigment in the paint industry
As an important constituent […]

Titania mineral source occurs plenty in nature. It is mostly available in beach sand associated with the other rare earth minerals like zircon, thorium etc. The raw sand is mined and pre-concentrated. It is then upgraded by various process routes and passed through filter and rotary dryer. In the next stage it is passed through […]

Hydro Thermal Method
Hydro Thermal Oxidation of Zircon Metal
The Hydro Thermal Oxidation method is also called as break down method. In this method the high purity (99.9%) Zirconium metal powder is treated with water in a specially designed test-tube-type vessel under a pressure of 100 MPA and at a temperature of upto 700oC.
After […]

Hydro Thermal Method
This method is a potential method for obtaining pure and nano particle size Zirconium Oxide powder, based on Zirconium compounds derived from natural Zircon Sand. Hydro Thermal technique is once again classified into two different types

Hydro Thermal Crystallization of Amorphous Zirconia
Hydro Thermal Oxidation of Zircon Metal

Hydro Thermal Crystallization […]

Fluoride and Sulphuric Acid Reaction Method:
Fluoride Method:
Zircon, Potassium Fluoride and Potassium Chloride is first mixed in a blender to ensure uniform mixing. The mixture is shifted to a crucible and heated in a furnace to a temperature of 1700oC. The reaction helps to form potassium zirconia fluoride in soluble form. The repeated purification […]

Plasma Arc Method
This is a most advanced technique for making very fine sub micron size Zirconia Powder. In this process, the washed, magneted zircon sand is pulverised to a certain particle size. The pulverised sand particles are injected into a plasma reactor where intensive heat is maintained to the level of more than […]

Chlorination and Thermal Decomposition Method:
The naturally available Zircon and Carbon are mixed in a blender and then ground in an attritor mill for forming fine powder. The powder is then palatalized in a palatalizing machine. The pallets are then directly chlorinated at a temperature of 800oC to 1400oC in a shaft furnace or in a […]
