Samarium cobalt magnets are also known as samarium cobalt magnets, samarium cobalt permanent magnets, samarium cobalt permanent magnets, rare earth cobalt permanent magnets, and the like. It is a magnetic material made of lanthanum, cobalt and other metal rare earth materials by smelting into alloys, pulverized, pressed and sintered. It has high magnetic energy product and extremely low temperature coefficient.

Application of amorphous boron powder

Submitted by admin on Tue, 10/09/2018 - 02:11

The content of boron in the earth's crust is 0.001%. amorphous boron powder is a black or silver grey solid. The crystal boron is black, the hardness is second only to diamond, and the texture is brittle. Stable in air at room temperature, oxidized when heated to 300 ° C, and ignited at 700 ° C. Mr10.81. ρ = 2.37 g/cm 3 (amorphous); 2.34 to 2.46 g/cm 3 (crystal). The melting point is 2177 to 2301 ° C; the boiling point is 2550 to 2658 ° C. amorphous boron powder is named Boron and its name is derived from Arabic. The original meaning is "flux".

What is SnO2

Submitted by admin on Mon, 10/08/2018 - 02:20

SnO2, same as the Stannic oxide, chemical formula is SnO2. It is a white  or light gray square, hexagonal or orthorhombic powder. The temperature of 1630 ° C, the boiling point is 1800 ° C. Density is 6.95 g / mL at 25 ° C, it is also an excellent transparent conductive material. It is the first transparent conductive material to be put into commercial use. In order to improve its conductivity and stability, it is often used for doping, such as SnO2:Sb, SnO2:F, etc.
