What exactly is a thermal battery? Thermal batteries are also called thermally activated reserve batteries. The single cell of the thermal battery is composed of a positive electrode (FeS iron-sulfur alloy), an electrolyte, and a heating sheet (iron powder). The main body of the heating sheet is iron powder, and its conductivity is relatively high. FeS iron sulfur is a semiconductor material, whic...

Boron carbide has a high neutron absorption capacity. The neutron capture cross-section is high and the capture energy spectrum is wide. The thermal cross-section of 10B is as high as 347 × 10-24 cm2, second only to a few elements such as gadolinium, samarium, and cadmium. At the same time, compared with pure elements B and Gd, B4C is low in cost, does not produce radioisotopes, has low secondary ...

By mixing a small amount of nano silica into concrete, ultra-high strength and ultra-high durability concrete can be easily prepared. At present, a large number of research results have proved that nano SiO2 has a good modification effect on cement. The cement paste doped with nano silica has reduced fluidity, shortened setting time, and significantly improved early strength. Nano-doped nano silic...

1. Application of Nano Iron Oxide in Decoration Materials In pigments, nano-iron oxide is also called transparent iron oxide (iron penetration). The so-called transparency does not specifically refer to the macroscopic transparency of the particles themselves, but refers to the dispersion of pigment particles in the organic phase to make a layer of paint film (or oil film). When light is irradiate...
