What Are The Hazards Of Titanium?

wallpapers News 2020-12-28
Among the metal elements, titanium has a high specific strength. It is a high-strength but low-quality metal with fairly good ductility (especially in an oxygen-free environment). The surface of titanium is silver-white and metallic. Its melting point is quite high (over 1,649 degrees Celsius), so it is a good refractory metal material. It is paramagnetic, and its electrical and thermal conductivity are very low.
 
Harm
 
Nettle has a titanium content of up to 80 parts per million.
 
Titanium is not toxic, even in large doses. Titanium does not have any natural effects in the human body. It is estimated that a person consumes about 0.8 mg of titanium per day, but most of it passes through without being absorbed. However, tissues containing silica tend to bioaccumulate titanium. In plants, an unknown mechanism might use titanium to stimulate carbohydrate production and promote growth. This may explain why the titanium content of most plants is about 1 part per million (ppm), while the titanium content of edible plants is about 2ppm, and horsetail and nettle can reach up to 80ppm.

 
The powdered titanium and the shaved titanium flakes are easy to cause fires and explode due to heating in the air. Water and carbon dioxide fire extinguishing methods are not effective on burning titanium; D-type dry powder fire extinguishing agents must be used instead.
 
When producing or handling chlorine, you must be careful to note that titanium can only be used where there is no dry chlorine around, otherwise it will cause a titanium/chlorine fire. Even wet chlorine gas is a fire hazard, because wet chlorine gas may dry out unexpectedly under abnormal weather conditions.
 
The new unoxidized surface of titanium may catch fire when it comes in contact with liquid oxygen. This surface can be formed by the collision of the oxidized titanium surface with a hard object, or in the cracks caused by mechanical strain. Therefore, the use of titanium in liquid oxygen systems is likely to have restrictions, such as the aerospace industry will have such systems.
 
Titanium powder use
 
Used in aerospace, spraying, metallurgy, fireworks and other industries.
