最近的资料曾介绍了一系列工艺参数——蒸发温度、冷却剂、表负压等对分散度在空间的沉积形状,或对镁粉表面的影响结果。按着过去的蒸汽沉积法,工艺过程是粉末沉积在稀薄的惰性气体中运动着的冷表面上。研究是在上述的大型试验装置里进行的。牌号1的金属镁装入厚壁的石墨坩埚,装置 Recent data have introduced a series of process parameters - evaporation temperature, coolant, surface pressure and other dispersion of the shape of the space in the deposition, or magnesium powder surface results. According to the vapor deposition method of the past, the process was that the powder was deposited on a cold surface moving in a thin inert gas. The study was conducted in the above-mentioned large-scale test apparatus. Grade 1 metal magnesium loaded thick-walled graphite crucible, device
