What is Titanium?

 

Titanium, identified by the chemical symbol Ti and atomic number 22, has been known since 1971. Renowned for its resilience, it stands up against a broad spectrum of corrosive agents, from gases and acids to salt water and the challenges of the marine environment.

Moreover, titanium’s resistance to micro-organism induced corrosion, its non-reactive nature in the body, and its virtually non-magnetic properties make it invaluable in numerous applications, especially where low electromagnetic interference is essential.

The Evolution of Titanium: A Historical Timeline

 

• 1791 – English chemist William Gregor discovers titanium in the mineral ilmenite (FeTiO3).
• 1795 – Impossible to isolate Ti from, so Martin Klaproth is named in honour of the Titans – gods of ancient Greek mythology.
• 1910 – finally separated by heating titanium tetrachloride (TiCl4)
• 1915 – first applications – parts of military aircraft
• 1950s – still the most widely used alloy, Ti-6Al-4V, developed in the Soviet Union, but soon also produced in the USA
• 1950s – 60s – applications in military and civil aerospace industry and space programme
• 1960s – new alloys developed and produced in the USA, Russia and Japan
• The 90s – now massive production in China

Characteristics of Titanium

 

• Superior Corrosion Resistance: Titanium stands up exceptionally well to seawater, making it the choice material for marine applications.
• Robust Strength: Besides its impressive tensile and yield strengths, titanium boasts great formability, retaining rigidity post-forming.
• Biocompatibility: Being devoid of harmful metals, titanium is body-friendly, posing no health risks when used in medical or daily life applications.
• Efficient Heat Conduction: The inherent properties of titanium allow for thinner construction compared to many metals. Its resistance to scaling also means heat is transmitted more efficiently.
• Endurance at High Temperatures: With a melting point of 1668°C, titanium maintains its integrity even at 600°C for extended durations and remains undeformed after exposure to open flames.
• Light yet Strong: Although denser than aluminum, titanium is lighter than steel. This means titanium components offer strength comparable to steel but at a fraction of the weight.
• Natural Antimicrobial Traits: Studies indicate titanium’s unique ability to inhibit bacterial growth. In titanium surroundings, harmful microorganisms struggle to thrive.
• Performance in Cold Climates: As temperatures dip, titanium’s strength rises. Even at a frigid -235°C, it showcases remarkable ductility and toughness, sidestepping the pitfalls of cold brittleness.
• Visual Appeal: The oxide layer on titanium can produce a range of colors, enhancing its aesthetic value. This visual versatility doesn’t come at the cost of increased maintenance, making it both beautiful and practical.

Advantages and Disadvantages of Titanium

 

Advantages

• Durability: Titanium is resistant to corrosion, seawater, and extreme temperatures, making it a reliable choice for various applications.
• Strength and Weight: Lighter than steel but stronger, titanium also offers double the strength of aluminum.
• Chemical Properties: Insoluble in water but soluble in concentrated acids, titanium boasts a unique chemical resilience.
• Versatility: Combining both ductility and toughness, titanium is adaptable to various manufacturing processes.

Disadvantages

• Expensive Material: Titanium comes at a high cost compared to other metals.
• Production Costs: Manufacturing titanium products can be more costly due to its unique properties.
• Manufacturing Challenges: Producing titanium can be complex, requiring specialized techniques and equipment.

Why is Titanium so Expensive?

 

Although titanium is abundant in nature, it is not found as a pure element, but rather as titanium dioxide (TiO2) in its ore, rutile. Extracting pure titanium from its ore is a complex and energy-intensive process, which contributes significantly to its high cost. Here’s a breakdown of why:

• Extraction Process: Unlike other metals like aluminum or copper, titanium cannot be extracted using a blast furnace due to its high reactivity with carbon. Instead, the Kroll process, a labor-intensive and costly method, is employed to extract titanium. This process accounts for the production of nearly 99% of the world’s titanium.
• Energy Consumption: The energy requirement for the Kroll process is substantially high. Since energy costs form a significant portion of production expenses, the high energy consumption in titanium production elevates its overall cost.
• Raw Material Scarcity: While titanium is the ninth most abundant element on Earth, finding and mining high-grade, commercially viable deposits of its ore is challenging.
• Comparison with Other Metals: When we compare the cost of titanium with other metals, it becomes evident how expensive it is. For instance, aluminum costs around $1/kg, copper is priced at $8/kg, while titanium stands out at a whopping $25/kg.

In essence, the intricate and energy-consuming extraction process, combined with the challenges of sourcing high-grade ore, make titanium a premium-priced metal in the market.

The Production of Titanium: An Overview

 

Titanium, naturally occurring combined with elements like oxygen and iron, must undergo multiple processes to reach its usable form. The journey of transforming titanium from its ore state to a finished product can differ based on its intended application, but the initial step is always isolating the titanium.

Central to titanium production is the Kroll process. Here’s a concise rundown:

1. Titanium Ore Extraction: Typically, ores like ilmenite, rutile, and leucoxene are mined, with their primary component being titanium dioxide (TiO2).
2. Conversion to TiCl4: This titanium dioxide is reacted with chlorine gas, producing titanium tetrachloride (TiCl4) along with other compounds.
3. Producing Titanium Sponge: In a high-temperature vacuum furnace, magnesium is used to reduce the TiCl4, resulting in a porous form of titanium known as titanium sponge.
4. Melting and Casting: The sponge is subsequently melted, often via electron beams, and cast into various shapes suitable for diverse applications.

While the Kroll process dominates the industry, emerging methods like the FFC Cambridge and Armstrong processes aim to make titanium production more cost-efficient and environmentally friendly.

What is the Kroll Procedure?

 

The Kroll process, pioneered by metallurgist William J. Kroll in the 1940s, stands as the primary method for extracting metallic titanium. This innovative procedure involves the reduction of titanium tetrachloride (TiCl4) using magnesium (Mg) under elevated temperatures within a sealed environment. The outcome is a porous metallic form called titanium sponge, which can be further refined into diverse formats such as ingots, bars, and sheets.

Titanium, recognized for its impressive strength, light weight, and exceptional resistance to corrosion, finds extensive application across industries. From aerospace components and medical implants to sports equipment, the use of titanium is pervasive. However, the intricate nature of the Kroll process makes it a relatively expensive method, primarily due to the labor-intensive steps it entails.

Understanding Titanium Products
