What is Titanium Carbide TiC Powder?
The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the Titanium Carbide powder?
Introduction to Titanium Carbide TiC Powder
The chemical formula for titanium carbide is TiC. It is a steel-gray crystal with a metallic luster. It has thermal conductivity and electrical conductivity, and its electrical conductivity decreases with the increase of temperature, so it shows the property of medal. It is a hard, high melting point compound, second only to diamond in hardness, with a microhardness of 2850 kg/mm2. The lattice constant a=4.173×10-8cm. Melting point 3150℃, boiling point 4820℃, relative density 4.9. TiN and TiO have the same lattice and the same parameters, so a series of continuous solid solutions can be formed between them. When heated to above 1500℃ in H2 gas, C removal gradually occurs. The mixture of Ti(C, N) carbon nitride reacts with N2 gas above 1200℃ to form a variable composition. The oxidation rate of TiC is slow at 800℃, but the powder TiC can be burned in O2 at 600℃ to generate TiO2 and CO2. At 1200℃, TiO2 and CO are produced by reaction with O2 gas. It does not interact with water, but can react with water vapor to generate TiO2, CO, and H2 at temperatures above 700℃. It does not react with CO, but reacts with CO2 at 1200℃ to generate TiO2 and CO. Insoluble in hydrochloric acid and lye, soluble in nitric acid and aqua regia.

Preparation Methods of Titanium Carbide TiC Powder
1. Carbothermic reduction
TiO2 was reduced with carbon black at 1700-2100℃, and the chemical reaction formula was: TiO2(S)+ 3C(s)=TiC(S)+2CO(g).
2. Direct carbonization method
TiC was prepared by the reaction of Ti powder and carbon powder.
Due to the difficulty in preparing submicron Ti powder, the application of this method is limited. The above reaction takes 5-20 hours to complete, the reaction process is difficult to control, and the reactants agglomerate seriously. It requires further grinding to prepare fine TiC powder. In order to obtain a purer product, it is necessary to purify the fine powder after ball milling by chemical method.
3. Chemical vapor deposition
The synthesis method utilizes the reaction between TiCl4, H2 and C.
The reactants react with hot tungsten or carbon monofilaments. TiC crystals grow directly on the monofilaments. The yield and sometimes even quality of TiC powders synthesized by this method are strictly limited.
4. Sol-gel method
The invention relates to a method for preparing small particle size products by fully mixing and dispersing materials with solution. It has the advantages of good chemical uniformity, small powder size, and narrow distribution, low heat treatment temperature, but the synthesis process is complex, drying shrinkage is large.
5. Microwave method
Using nano TiO2 and carbon black as raw materials, using the principle of carbon thermal reduction reaction, using microwave energy to heat the material. In fact, the dielectric loss of materials in the high-frequency electric field is used to convert microwave energy into heat energy, so that nano TiO2 and carbon can synthesize TiC.
Applications of Titanium Carbide TiC Powder
1. Used in cutting tools, wear-resistant coating, mold manufacturing, and other fields;
2. Raw materials for the production of ceramics and hard metallurgical parts by powder metallurgy, such as drawing film, hard alloy die, etc. Polyphase ceramics can be applied to hard cutting tools, military armor materials, aerospace components, such as gas tanks, engines, nozzle lining, turbine rotors, blades, and structural components in nuclear reactors;
3. As a coating material, it can be used in diamond coating, tritium anti-coating in the fusion reactor, electric contact coating, excavator cutter coating, as well as foam ceramics, infrared radiation ceramics, etc.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the Titanium Carbide powder will develop in the future is still uncertain.
