In this study, thermal analysis and combustion experiments, such as combustion calorimetry or
the measurement of burning rate and combustion temperature were carried out to clarify the thermal
reaction and combustion reaction of boron - cupric oxide mixture. The results obtained are
as follows:
The mixture of boron with cupric oxide caused an intense exothermic reaction, but the thermal
reactivity was different with the shape and the composition of the sample in which a boron - rich
condition showed higher thermal reactivity. The linear burning rate, heat of combustion and
combustion temperature of boron - cupric oxide mixture had the maximum value at fuel - rich
condition of the equimolar composition. The pressure effect was also recognized with regard to
the linear burnhg rate and heat of combustion. The fractional oxidation of boron for the combustion
at atmospheric pressure was 81 - 83 ％ for stoichiometric and oxidizer - rich conditions.
Under pressurized conditions, it increased with increasing ambient pressure and amount of oxidizer,
and a complete oxidation of boron was attained at the oxidizer - rich and pressurized composition.
ホウ素と酸化銅の混合物は激しい発熱反応を示すが, その反応性は試料の形状や組成によって異なった。 その際に, 特にホウ素過剰の条件で高い反応性を示した。 ホウ素 - 酸化銅混合物の燃焼速度, 燃焼熱および燃焼温度はホウ素過剰の条件下で最高値を示した。 燃焼反応に及ぼす圧力の影響も認められた。
