In the development processing, tungsten carbide encountered contradiction between strength and hardness, which is with high hardness but low strength, high strength but low hardness. WC particle size of tungsten carbide is always greater than its original particle size with traditional methods, and usually in a few microns.

However, many countries have encountered difficulties in the study of nano-carbide, the main problems are reflected in two aspects: First, the preparation of nano-WC-Co composite powder activity is very sensitive to temperature, in the high temperature will be immediately grown up. The current research and development trend is to improving the preparation of ultra-fine WC-Co composite powder method and improve the sintering processing. The compactness and uniformity of the tungsten carbide prepared by low pressure isostatic pressing sintering process are well, and the process has the advantages of short production cycle and small process loss.

Mobile emission catalyst helps in emission reduction from automotive and stationary engines from many vehicles such as cars, trucks, commercial vehicles and buses. It reduces emission of various gases such as carbon dioxide (CO2), carbon mono oxide (CO), hydrocarbons (HC), oxide of nitrogen (NOx) and other gases which are produced due to incomplete combustion of fuel. 

China's financial services authorities required major executives of the Shanghai-based bitcoin trading platform BTCC on Friday to rectify misbehavior in the trading of the virtual currency - and to raise awareness of risks as the value of bitcoins experienced wild fluctuations.

In the field of armor piercing, the United States is well ahead of all the countries in the world - including tungsten alloy armor piercing projectiles.
