Occurrence of fibrous sodium aluminumtetrafluoride particles in potrooms of the primary aluminum industry.
研究发现原铝工业工作环境中存在无机纤维颗粒，浓度范围为9至720纤维/立方厘米，直径小于0.1微米，长度小于5微米，经鉴定为四氟铝酸钠。
Inorganic fibrous particles have been found in the work environment of the primary aluminum industry. Based on scanning electron microscopic analysis, the concentrations ranged from 9 to 720 fibers/cc. The fibers were generally thinner than 0.1 micron in diameter and shorter than 5 microns. By electron microscopy, energy dispersive X-ray microanalysis, and selected area electron diffraction the fibers were identified as sodium aluminumtetrafluoride.
