Barium oxide thermal conductivity

Table 7.8 illustrates this same concept for the molybdenum-barium chromate-potassium perchlorate system. Here, KCIO4 is the better oxidizer. An interesting study on this system showed that even when the excess metal in it is inert silver powder, rather than molybdenum, the bum rate is still enhanced, indicating that the enhanced thermal conductivity due to the excess metal is indeed a significant factor. ... 

DIFLUOROETHANE or 1,1-DIFLUOROETHANE (75-37-6) Flammable gas (flamma bility limits 3.7-18% by volume in air). Violent reaction with strong oxidizers, barium, sodium, and potassium. Incompatible with powdered aluminum, liquid oxygen, potassium, sodium. May form explosive compounds with divalent light metals and metallic azides. Attacks some metals in the presence of moisture. Undergoes thermal decomposition when exposed to flame or red-hot surfaces. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

The pyrotechnic paper or heat paper supplies the thermal energy to elevate the thermal battery cell to operating temperatures. The pad consists of a ceramic fibre paper, which acts as a binder/carrier for a slurry of zirconium metal fuel and barium chromate oxidant. The paper is extremely fast burning, making it ideal for a fast activation cell. Because the remaining ash of the heat pad is electrically non-conductive, it is necessary to provide a means for series intercell connection.
