What kind of material is Nitinol?

 Overview of Nitinol

Nitinol is a special alloy that can automatically recover its plastic deformation under a certain temperature. The expansion rate is greater than 20%, the fatigue life is 1×10-7 power, the damping characteristic is 10 times that of ordinary springs, and the corrosion resistance is better than the best medical stainless steel at present. Therefore, it can meet the needs of various engineering and medical applications and is a very excellent functional material.

What kind of material is Nitinol?

Application of Nitinol Powder

Nitinol powder can meet the needs of various engineering and medical applications and is an excellent functional material. In addition to its unique shape memory function, memory alloy also has excellent functions such as wear resistance, corrosion resistance, high damping and super elasticity.

1. It is not easy to deform. Nickel-titanium alloy material undergoes reverse phase transformation, continuously heating and cooling, and the material will automatically return to its original shape. The shape memory effect is actually a thermally induced phase transformation process of NiTi alloy.

2. Good elasticity. It refers to the phenomenon that the strain under the action of external force is much larger than the elastic limit strain, and the strain can automatically recover during the unloading process. That is to say, in the state of parent phase, due to the action of external stress, a stress-induced martensitic transformation occurs. The alloy exhibits a mechanical behavior different from that of ordinary materials, and its elastic limit far exceeds that of ordinary materials.

3. Applicable to the construction industry. The orthodontic force of superelastic Nitinol alloy changes with temperature. When the amount of deformation does not change. As the temperature increases, the orthodontic force increases. On the one hand, it can maintain good elasticity when the overall temperature of the building is too high to cause the overall thermal expansion and contraction of the building. The shape can change with the change of temperature, and it will not be broken or deformed and cannot be restored to its original shape.

4. It has good shock absorption capability. When the building vibrates due to geological factors and other reasons, Nitinol will not shake too much like steel, because the initial amplitude of super-elastic Nitinol wire is only half of that of steel. Its shock absorption characteristics save the building. It is very important, and its uses are much broader than steel bars.

Lithium nitride is the only stable alkali metal nitride

圖片
  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and ni...

Is zinc sulfide fluorescent or phosphorescent?

圖片
  Overview of Zinc Sulfide ZnS Zinc sulfide  is a white to off-white or light yellow powder, which becomes darker when exposed to light, stable in dry air, and gradually oxidized to zinc sulfate when stored for a long time in humid air or containing water. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. Relative density 3.98 (alpha type), (d25) 4.102 (beta type). irritating. Is zinc sulfide fluorescent or phosphorescent? Zinc sulfide  is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, phosphorescent materials emit absorbed energy immediately. What are the properties of zinc sulfide? Zinc sulfide  is white or slightly yellow powder. Turns into crystals when burned in H2S gas. Its α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102 g/cm3, w...

Cuprous oxide is also known as an inorganic compound of copper oxide

圖片
  Overview of Cuprous oxide  Cu2O  Powder Cuprous oxide,   the chemical formula is Cu2O, is monovalent copper oxide, a bright red powder solid, almost insoluble in water, in acidic solution disproportionation into copper and copper elemental, in the wet air gradually oxidized into black copper oxide. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paint(used to kill lower Marine animals), insecticides, and various copper salts, analytical reagents, red glass, but also used in the preparation of copper plating and copper plating alloy solution. Copper(I)oxide is also known as an inorganic compound of copper oxide with the chemical formula Cu2O. It's essentially covalent. The copper(I)oxide crystallizes in a cubic structure. When heated, hydrogen tends to reduce the disproportionation it undergoes in acidic solutions that produce copper (II) ions and copper. When the copper oxide is gently heated with metal copper, it is converted to cuprous ...
