What is Titanium carbide?
The chemical formula of titanium carbide is TiC and the molecular weight is 59.89. Gray metal-like face-centered cubic lattice solid. The melting point is 3140±90°C, the boiling point is 4820°C, and the relative density is 4.93. The hardness is greater than 9. Insoluble in water, soluble in nitric acid, and aqua regia. It is stable to air when it is lower than 800℃, it is corroded by air when it is higher than 2000℃, and it can react with pure O2 when it is 1150℃. Production method: The mixture of titanium powder and carbon obtained by reducing TiO2 by hydrogen is acted at high temperature, or TiO2 and carbon powder are mixed and pressed into agglomerates, and then heated to 2300-2700°C in an electric furnace and carbonized in H2 or CO atmosphere And gotta. Uses: To make cemented carbide, also used as an electrode and abrasive for arc lamps.
The synthesis method of titanium carbide
Using carbon black to reduce TiO2, the reaction temperature range is 1700-2100℃, and the chemical reaction formula is TiO2(s)+3C(s)=TiC(S)+2CO(g).
Ti powder and carbon powder react to generate TiC. The chemical reaction formula is: Ti(s)+C(s)=TiC. Because it is difficult to prepare sub-micron metal Ti powder, the application of this method is limited. The above reaction takes 5-20 hours to complete, and the reaction process is difficult to control. The reactants agglomerate seriously, and further grinding processing is required to prepare fine particles. Granular TiC powder. To obtain a purer product, it is necessary to chemically purify the fine powder after ball milling.
The synthesis method utilizes the reaction between TiCl4, H2, and C. The reactant reacts with the hot tungsten or carbon monofilament, and TiC crystals grow directly on the monofilament. The TiC powder synthesized by this method has strict limits on its output and sometimes even it's quality. In addition, due to TiCl4 and the product, The HCl contained in it is strongly corrosive, so be careful when synthesizing it.
A method for preparing small particle size products by thoroughly mixing and dispersing materials using a solution. It has the advantages of good chemical uniformity, small powder particle size and narrow distribution, and low heat treatment temperature, but the synthesis process is complex and the drying shrinkage is large.
Uses of titanium carbide
Titanium carbide is usually used as an additive for cutting tool materials and metal bismuth, zinc, and cadmium melting crucibles to prepare semiconductor wear-resistant films and HDD large-capacity memory devices.
At the same time, titanium carbide is also an important component of cemented carbide and is used as a deoxidizer in the steelmaking industry.
It can also be used as a cermet, which has the characteristics of high hardness, corrosion resistance, and good thermal stability.
