Process

High-purity/electronic-grade titanium tetrachloride (TiCl₄) can be applied in multiple fields:Titanium dioxide (TiO₂) production: As a key raw material in the chlorination process for manufacturing high-performance pigments.Metallic titanium production: Used in processes such as the magnesium reduction method to produce metallic titanium and titanium alloys.Semiconductor industry: Serves as a precursor in chemical vapor deposition (CVD) for preparing titanium nitride (TiN), titanium oxide (TiO₂), and other thin-film materials.Photocatalysis and functional ceramics: Used in the synthesis of photocatalysts (e.g., TiO₂) and high-performance ceramic materials.Other applications: Includes use as a polymerization catalyst, in the preparation of special optical coatings, and in high-temperature resistant materials.Industrial production of titanium tetrachloride (TiCl₄) mainly adopts the chlorination method, where chlorine gas reacts at high temperature with titanium-rich materials such as high-titanium slag or rutile in a fluidized bed reactor. Additionally, TiCl₄ can be produced by chlorinating mixtures of ilmenite and carbon, or via molten salt chlorination processes to obtain crude TiCl₄.Jinhong Gas performs multi-stage distillation and precision purification on industrial-grade crude TiCl₄ to produce electronic-grade TiCl₄ (7N). The key lies in accurately controlling impurities with similar boiling points (e.g., tin tetrachloride) and strictly removing trace moisture and metal ions before filling.The annual production capacity of 7N (99.99999%) and above electronic-grade TiCl₄ at Jinhong Gas can reach 10 tons.

Applications

Semiconductors

Electronic-grade titanium tetrachloride (≥6N) is mainly used in semiconductor manufacturing for chemical vapor deposition (CVD) or atomic layer deposition (ALD) processes. It serves as a key precursor for producing high-performance titanium nitride (TiN) metal gates, barrier layers, and capacitor electrodes.

Renewable Energy & Optics

In the fields of renewable energy and optics, titanium tetrachloride is a fundamental raw material for high-performance titanium dioxide (TiO₂) nanomaterials. It is widely applied in dye-sensitized solar cells, photocatalysts, and functional optical coatings.

Industry

In industry, titanium tetrachloride is primarily used for the production of metallic titanium and titanium alloys. It is also a core raw material for the manufacture of high-quality titanium dioxide pigment via the chlorination process.

Chemical Industry

In the chemical sector, titanium tetrachloride is an essential component of Ziegler–Natta catalyst systems used for olefin polymerization. It can also serve as an intermediate in the synthesis of other organotitanium compounds and specialty chemicals.

Research

In research, high-purity titanium tetrachloride is used as a reference material or high-purity raw material for developing new materials, studying vapor deposition processes, and performing related analytical testing.

Frequently Asked Question

What product specifications can you provide?

Cylinder: MO source cylinder Valve: Customizable as required (Note: Specific specifications can be adjusted according to customer needs.)

How is titanium tetrachloride produced?

Industrially, titanium tetrachloride is typically produced via the chlorination method, where chlorine gas reacts at high temperature with titanium-rich materials such as high-titanium slag or rutile to generate crude TiCl₄. Jinhong Gas purifies the crude TiCl₄ through multi-stage distillation and other purification processes to obtain high-purity products.

Is titanium tetrachloride dangerous?

Yes. Titanium tetrachloride is highly corrosive and reacts violently with water, producing dense white fumes containing hydrochloric acid and titanium dioxide. It strongly irritates the eyes, respiratory tract, and skin. Therefore, strict safety procedures must be followed during storage, transport, and use.

What is the environmental impact of titanium tetrachloride?

TiCl₄ itself poses acute hazards to water and soil. Its primary environmental risk comes from hydrolysis, which generates hydrochloric acid mist and chlorine-containing compounds, potentially causing local acidification. Professional neutralization and handling are required.
