Silicon Nitride Ceramic:
Researchers at the University of Sheffield in the United Kingdom have developed an artificial "plastic blood" that looks like a thick paste. As long as it is dissolved in water, it can be transfused to patients, which can be used as a blood substitute in emergency procedures. This new type of artificial blood is composed of plastic molecules. There are millions of plastic molecules in a piece of artificial blood. These molecules are similar in size and shape to hemoglobin molecules. They can also carry iron atoms and transport oxygen to the whole body like hemoglobin. Since the manufacturing raw material is plastic, this artificial blood is light and easy to carry, does not require refrigerated storage, has a long useful life, higher work efficiency than real artificial blood, and lower cost. A scientific research team in Mexico developed a new type of bulletproof plastic in 2013, which can be used to make bulletproof glass and bulletproof clothing. The quality is only 1/5 to 1/7 of traditional materials. This is a specially processed plastic material, which is superior in elasticity compared with the normal structure of plastic. Tests have shown that this new type of plastic can withstand bullets with a diameter of 22mm. Normal bulletproof materials will be damaged and deformed after being hit by a bullet, and cannot be used anymore. After this new material is impacted by a bullet, although it will temporarily deform, it will soon return to its original shape and can be used continuously. In addition, this new material can evenly distribute the impact of bullets, thereby reducing harm to the human body.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
