What’s the purpose of titanium carbide?
TiC (titanium carbide) is a hard (Mohs 9.-9.5), refractory ceramic materials, which is similar to that of tungsten carbide. This material appears as a powdery black with the face-centered cubic sodium chloride crystal structure.
This is a rare form of the mineral khamrabaevite that occurs naturally. It was discovered on Mount Arashan (modern Kyrgyzstan) in the Chatkal district, USSR. Ibragim Khumbrabaevich Khamrabaevich Khamrabaev was the director for Geology and Geophysics in Tashkent. The crystals are approximately the same size as natural ones, ranging from 0.1 to 3mm.
The titanium carbide can also be used in nickel-cobalt matrix ceramic to make tools bits that are not tungsten. This increases the precision, cutting speed and smoothness.
Addition of 33% to 65% of titanium carbide can increase the resistance to corrosion and wear of tungsten carbide-cobalt. This creates a stronger solution, which is less brittle and more susceptible to breaking.
You can etch titanium carbonide with reactive-ion engraving.
Where is titanium carbide manufactured?
TiC titanium carbide, which is hardened crystalline powder with the composition TiC (titanium dioxide) at temperatures over 1800C, is created by reacting carbon black and titanium dioxide. This powder is made by combining cobalt and nickel to make it compact for cutting or heat resistance parts.
Application of titanium carbide TiC dust
It is commonly used for making cermets. Cermets can be used to quickly machine high-speed steel materials. This surface treatment is abrasion resistant and can be applied to metal parts such as watch mechanisms or tool bits. For atmospheric reentry, titanium carbide can also be used as heat shielding.
Used as an additive in cutting tools and preparation of metal bismuth.
Use titanium carbide as an additif for metal bismuth melting bismuth or zinc cutting tools, preparation of semiconductor wear-resistant films, and large-capacity HDD memories.
A nanotech Titanium carbide-based approach suggests a breakthrough in hydrogen storage
China has just released new research that promises to improve the efficiency and sustainability of hydrogen storage. At a time when low carbon collection of this omnipresent gas could be a pathway to greener energy, it is being promoted as an option.
Nature Nanotechnology publishes this week’s research on a method that uses a titanium carbide alloy as a medium. It produces a “nano pumps” effect to store hydrogen. Comparable methods are less effective than the process described.
Hydrogen has been gaining interest in its potential as a renewable fuel. There are already fuel-cell cars on the market. The tiny molecules of hydrogen make storage difficult, despite some breakthroughs being made. Register readers pointed out this fact quickly.
Jianglan Shui (School of Materials Science and Engineering), Beihang University and his colleagues found that titanium carbide materials (technically called Ti2CTx – a type of MXene – could sustain 8.8wt% of hydrogen ratio at a pressure of 60 bars. This is considered “relatively safely”
According to the paper, Ti2CTx outperforms all other room-temperature storage materials for hydrogen storage. This is nearly twice as much storage capacity at the same pressure.
The hydrogen release is rapid and manageable. This makes it a promising strategy to design practical hydrogen storage material.
