论文摘要
对纯多晶固体和液体铍的热物理特性进行了审查，这些状态构成了对融合应用很重要的强烈等离子表面相互作用现象的建模（热分析，蒸气屏蔽，熔融，熔体运动，弧运动，尘埃，灰尘，尘埃运输，尘埃运输）。分析可靠的实验数据，分析潜在热量，比同等热容量，电阻率，导热率，质量密度，蒸气压力，工作功能，总半球发射率和从室温到Beryllium正常沸点的绝对热电功率，以及表面张力和动态均匀状态的正常沸点。建议对这些热物理特性的温度依赖性进行分析表达式，鉴于没有扩展的液体铍测量值，该表达式涉及高温外推。
The status of the literature is reviewed for thermophysical properties of pure polycrystalline solid and liquid beryllium which constitute input for the modelling of intense plasma-surface interaction phenomena that are important for fusion applications (thermal analysis, vapor shielding, melt motion, arcing, dust generation, dust transport). Reliable experimental data are analyzed for the latent heats, specific isobaric heat capacity, electrical resistivity, thermal conductivity, mass density, vapor pressure, work function, total hemispherical emissivity and absolute thermoelectric power from the room temperature up to the normal boiling point of beryllium as well as for the surface tension and the dynamic viscosity across the liquid state. Analytical expressions are recommended for the temperature dependence of these thermophysical properties, which involve high temperature extrapolations given the absence of extended liquid beryllium measurements.
