зеленый микропорошок бета частиц SiC

Sic powder,Beta sic particle info: 1. Grain Diameter D <=100nm,purity95+ 2.Grain Diameter D 100 1000nm,purity99+ 3.Grain Diameter D 100 1000nm,purity60+,the perfect substitute of MoS2. 4.Grain Diameter D1-50micron,adjustable flexibly. purity99+ Basicproperty: Decomposition Temperature (K): 2973 Heating Power (KJ/mol): 30.343 Linear Expansion Coefficient (373K): 6.58*10-6 Linear Expansion Coefficient£¨1173K): 2.98*10-6 Thermal Conductance: Compression Coefficient: 0.21*10-6 Density (288K) (g/cm3): 3.216 Hardness (Mohs): 9.5 Sic ( silicon carbide) has the good chemistry stability, low heated expansion, high efficiency of heat conductivity, electrical resistance comparing with metal being in the opposite direction , very hard and the level over 9.5 of Moss's. Sic ( silicon carbide) resists heat , grinding & crushing , especially in resisting hot shock wave, corrosion and radiation .The shape of β . Sic is crystallized as diamond . Harder than α sic reaching the level 9.5 of Moss's , good measure of tensile strength , best efficiency for electric current .if you have any questions about the powder, pls not hesitate to contact me. thank you.
