Iron(III) oxide, also named for ferric oxide, is the inorganic compound with the formula Fe2O3. When the size of the Fe2O3 Iron(III) oxide is small to nanometer(1~100nm), the surface atomic number, specific surface area and surface energy of the iron oxide particles increase sharply with the decrease of the particle size, which shows the features of small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect.

The most mature industry in which nano-calcium carbonate is applied is the plastics industry, which is mainly used in high-grade plastics products. It can improve the rheological property of plastic masterbatch and its formability. As a plastic filler, it can toughen and reinforce, improve the flexural strength and modulus of elasticity, thermal deformation temperature and dimensional stability of plastics, and at the same time give the plastics hysteresis.

Copper-nickel alloy

Copper-nickel alloy, copper and nickel are silver-white, with metallic luster, hence the name white copper.The strength, corrosion resistance, hardness, resistance and thermoelectric properties of pure copper and nickel can be significantly improved, and the temperature coefficient of resistivity can be reduced. Therefore, white copper has better mechanical and physical properties than other copper alloys, good ductility, high hardness, beautiful color, corrosion resistance and deep drawing properties.
