Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many Titanium Carbide TiC Powder,Overview of Titanium Carbide TiC Powder,Application of Titanium Carbide TiC Powder,Titanium carbide TiC powder price,Titanium Carbide TiC Powder Supplier.
Overview of Titanium Carbide TiC Powder
The chemical formula of titanium carbide is TiC. It is a steel grey crystal with a metallic sheen. It is thermally and electrically conductive, and its electrical conductivity decreases with increasing temperature, thus taking on the properties of a medal. It is a hard, high-melting compound, second only to diamond in hardness, with a microhardness of 2850 kg/mm2. The lattice constant a=4.173×10-8cm. The melting point is 3150 ℃, the boiling point is 4820 ℃, and the relative density is 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. Heating above 1500 °C in H2 gas, C removal occurs gradually. 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 °C, but TiC powder can be combusted in O2 at 600 °C to generate TiO2 and CO2. At 1200 °C, it reacts with O2 gas to generate TiO2 and CO. It does not interact with water, but can react with water vapor to generate TiO2, CO and H2 at temperatures above 700 °C. Does not react with CO, but reacts with CO2 at 1200 °C to generate TiO2 and CO. Insoluble in hydrochloric acid and lye, soluble in nitric acid and aqua regia.
Preparation method of titanium carbide TiC powder
1. Carbon black for carbothermic reduction at 1700-2100 ℃
To reduce TiO2, the chemical reaction formula is: TiO2(S)+3C(s)=TiC(S)+2CO(g).
2. Direct carbonization method TiC is prepared by the reaction of Ti powder and carbon powder. Ti(s)+C(s)=TiC The application of this method is limited due to the difficulty in preparing submicron titanium powders. The above reaction takes 5-20 hours to complete, the reaction process is difficult to control, and the reactants are seriously agglomerated. It requires further grinding to prepare fine TiC powder. In order to obtain a purer product, the fine powder after ball milling needs to be purified by chemical methods.
3. Chemical vapor deposition
The synthesis method utilizes the reaction between TiCl4, H2 and C
Reactants react with hot tungsten or carbon monofilament. TiC crystals are grown directly on the monofilament. The yield and sometimes even the quality of TiC powder synthesized by this method is severely limited.
4. Sol-gel method
The invention relates to a method for fully mixing and dispersing a material and a solution to prepare a small particle size product. It has the advantages of good chemical uniformity, small powder particle size, narrow distribution and low heat treatment temperature, but the synthesis process is complicated and the drying shrinkage rate is large.
5. Microwave method
Using nano-titanium dioxide and carbon black as raw materials, using the principle of carbothermal reduction reaction, the material is heated by microwave energy. In fact, the dielectric loss of the material in the high-frequency electric field is used to convert microwave energy into thermal energy, so that nano-TiO2 and carbon can synthesize TiC.
Application of Titanium Carbide TiC Powder
1. Titanium carbide powder is used for high temperature thermal spraying materials, welding materials, hard coating materials, military aviation materials, carbides and cermets.
2. Titanium carbide powder is used as an additive in the production of thermistors to improve wear resistance.
3. Titanium carbide powder has a NaCl-type cubic crystal structure. Adding 6% to 30% of TiC to WC-Co cemented carbide forms a TiC-WC solid solution with WC, which can significantly improve red heat, wear resistance, oxidation resistance, Corrosion resistance and other properties, more suitable for processing steel than WC-Co cemented carbide. Alloys such as Ni-Mo can also be used as binders to form tungsten-free cemented carbides, which can improve the turning speed and the precision and finish of the workpiece.
4. Used as tool material and additive for metal bismuth, zinc, cadmium smelting crucible, preparation of semiconductor wear-resistant film, HDD large-capacity storage equipment, is an important part of cemented carbide, used as deoxidizer in steelmaking industry, also Used as cermet, it has the characteristics of high hardness, corrosion resistance and good thermal stability.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".
In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.
The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.
As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.
Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV. Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
