Thermal conductive filler is a functional material added to matrix materials such as plastics, rubber, adhesives, etc. to improve their thermal conductivity. They significantly improve the thermal conductivity efficiency of composite materials by forming thermal conduction pathways or networks, and are widely used in electronic device heat dissipation, LED lighting, energy storage, aerospace and other fields.

Flake silver powder and spherical silver powder are two types of silver powder used in various industries. Although they are both made from silver, they have different characteristics and unique applications. This article will cover the differences between flake silver powder and spherical silver powder and their applications in different industries.

​Nano silver powder refers to metallic silver elemental powder with a particle size ranging from 1-100 nanometers (nm), also commonly known as nano silver or silver nanoparticles. Due to its unique physical and chemical properties, it plays a key role in multiple cutting-edge fields such as electronics, medicine, catalysis, and more. The particle size distribution range of nano silver powder is narrow, with commonly used particle sizes of 20nm, 50nm, 80nm, and 100nm. The purity of nano silver powder can reach 99.99%. We can also supply nano silver powder and aqueous dispersion.

Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal. The hardness is lower than industrial diamond, but higher than silicon carbide. Compared to most pottery, it has lower fragility. Has a large thermal neutron capture cross-section. Strong chemical resistance. Not susceptible to corrosion by hydrogen fluoride and nitric acid. Dissolved in molten alkali but insoluble in water and acid.

​The surface modification of silicon nitride powder is mainly achieved through physical and chemical methods to improve the physical and chemical properties of silicon nitride particles.

The 14th Shenzhen International Thermally Conductive Materials and Equipment Exhibition, also known as CIME2025, is set to take place on June 4-6, 2025, at the Shenzhen International Convention and Exhibition Center. With an expansive exhibition area of 20,000 square meters, the event is expected to host 500 exhibitors, 30 academic presentations, and attract approximately 30,000 professional visitors. CIME, originating in Shenzhen in 2013, has evolved over the past decade into a prestigious industry event in the field of thermal management and thermally conductive materials, now hosting exhibitions in Shenzhen in June and in Shanghai in December.
