Reticulated glassy carbon is a three-dimensional reticulated microporous material composed of
glassy foam, with porosity of 90% – 97%, low density (0.03g/cm3), high chemical stability, specific
surface area and conductivity, low thermal conductivity and coefficient of thermal expansion, high
structural strength and low resistance to fluid.
Basic properties of foam carbon：
A：characteristic
1、Low density, high strength
2、It can be made into both high thermal conductivity materials and low thermal conductivity materials
3、Good thermal shock resistance, able to withstand the impact of temperature change of 1 250 ℃
4、High temperature and corrosion resistance
5、Aperture can be foamed according to customer requirements
6、It has good processing performance and can be bonded with various common adhesives, so that carbon foam blocks are not restricted, and it is easier to form complex structures. Metal materials can be plated on the surface of foam carbon.
7、The material design can be flexible. The performance design can vary widely, and the performance of foam carbon can be achieved by engineering methods to meet the requirements of different densities, holes and hole connection methods.
