Cubic Beta Grade Silicon Carbide Nanoparticles Application

HW NANO silicon carbide nanoparticles 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.


silicon carbide nanoparticles resists heat , grinding & crushing , especially in resisting hot shock wave, corrosion and radiation .


Basic property: 
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


The shape of beta silicon carbide is crystallized as diamond . Harder than alpha silicon carbide reaching the level 9.5 of Moss's , good measure of tensile strength , best efficiency for electric current .


Silicon carbide nanoparticles has many advantages in strengthening, measure of tensile strength of substance, also has the special function on electric, wave, light.

Silicon carbide nanoparticles



At the present , the mainly application field for silicon carbide nanoparticles in below:


1. Brake pads fields.


Silicon carbide SiC composite material can meet 1650-1700 ℃ high temperature,  adding silicon carbide in the brake pads production progress can more effectively improve the braking stability,  solve the shortage of the poor adaptability caused by low static friction coefficient,  improve the sensitivity of the brakes.


2. Abrasives pastes.

Alpha SiC for rough cast, and for finishing polish,beta SiC is better and it can improve the smooth finish. Beta SiC can be used in grinding paste, grinding fluid, metal polishing, mechanical equipment area. High precision abrasive cloth belt and super wear resistant coating market is very good choice.

In order to improve the service life of diesel engine fuel injection nozzle matching parts, customer factory changed needle cut of fuel injection nozzle matching parts from the original GCr15 steel to 18Cr:Ni‘WA steel, and the Needle cut from GCr15 steel to WisCr4V. after carburizing and quenching,18crzni4wa material  mechanical processing manufaturability is less than GCr15 steel. in the cutting needle body holes and seat surface has good concentricity by Wx-042 processing, but mesopore finish only reach v10, also need to grinding, improve the data to V12.the test result showed that for chrome oxide paste and alumina grinding paste,the grinding cutting ability and pocessing finish is poor, it seriously affect the productivity and  product quality improvement.



3. Sharpening stone, Oilstone, Abrasive stone



Silicon carbide micron powders is widely used in the manufacture of advanced oil stone, super fine grinding oilstone, strong grinding oil stone, which are mainly used in machinery manufacturing, mold manufacturing, instruments and meters fields. Efficiency is twice as common oil stone's.


4. Cetamic material Sintering powder

Beta SiC can crystallization at 1800 ℃,it plays a good role for ceramics sintered density.
it is excellent Ceramic strengthening agent


5. The conductive material

Conductive, thermal conductivity of beta sic is better than alpha SiC for several times, it can be used in heater, heat exchanger, electric heaters, thermal shock resistance, not afraid of very hot and cold, and other materials will be easy to explode.


6. Special coating
foil coating in military enterprise. after electroless or composite plating cubic beta sic on wear-resistant products, wear-resisting life will be better. 


7. Carbon powder additives

After adding beta SiC, liquidity and adhesion of copier Carbon powder is increased, 5% of the additive is better.


8. Thermal conductivity, wear additives

Adding cubic silicon carbide to polymer composite materials and metal materials,which can greatly improve its thermal conductivity and lower coefficient of expansion, increase the wear resistance, etc., and the specific gravity of silicon carbide is small, no impact on the material structure weight.


We are professional manufacturer and supplier for cubic beta sic silicon carbide nanoparticles in small quantity for researchers and in bulk order for industry groups. Business involved all kinds of aspects: manufacturing, research, development, processing, supplying and after-sales service.
