吸收、分配和排泄
每天以100毫克/小时铝粉或92毫克Al/每2小时铝烟雾的形式吸入,持续9-13个月,两组动物肺部都显著蓄积了铝。暴露于铝烟雾的大鼠和仓鼠肺部铝的蓄积量远大于暴露于铝粉的。在接触新鲜空气后,两组铝氧化物迅速从肺部清除。暴露动物肺湿重、灰分和铝氧化物含量增加。最初的肺组织反应是肺泡空间内巨噬细胞的增殖以及脂质性肺炎。巨噬细胞灶性聚集位于小支气管和小肺动脉周围;观察到淋巴组织增生。长期接触铝粉后,大鼠在肺泡壁上出现透明质沉着,仓鼠在局部区域发展为脂质性肺炎。
Inhalation exposure to 100 mg/hr aluminium, in the form of powder, or 92 mg Al/ per 2 hr, as a fume, each day for 9-13 months showed a significant retention of aluminium in the lungs of both groups of animals. The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder. Following exposure to fresh air, aluminium oxide was cleared rapidly from the lungs of the both powder and fume groups. Weight of wet lung, ash and aluminium oxide content of lungs in exposed animals increased. The initial pulmonary tissue response was proliferation of macrophages within alveolar spaces as well as lipoid pneumonia. The focal aggregates of macrophages were located around the small bronchioles and small pulmonary arterioles; lymphoid hyperplasia was observed. After chronic exposure to aluminium powder, rats showed focal deposits of hyaline in alveolar walls, and focal areas of lipoid pneumonia developed in hamsters.

在新西兰雌性家兔接触氧化铝粉尘浓度为0.56毫克铝/立方米的环境中,经过5个月(每天8小时,每周5天)的暴露后,测定了其组织中的铝含量。这些动物大脑中的铝含量几乎是没有接触氧化铝的控制动物的两倍半。而其他组织中的铝含量仅略有增加。
... The concentrations of aluminum in tissues of female New Zealand rabbits exposed to /aluminum oxide/ dust at a concentration of 0.56 mg Al/cu m for 5 months (8 hr/day, 5 days/week) were determined. The amount of aluminum in the brains of the animals was nearly two and a half times as high as that of the control animals. The concentrations in other tissues were only slightly increased.

吸收、分配和排泄
标记的26Al放射性吸入研究是使用标记的伽马氧化铝进行的。结果显示,这种材料作为不溶性尘埃,大约45%在一天内从肺部清除,其余部分则从肺部缓慢机械清除。72天后,只有0.2%的氧化铝残留在肺部。肺部可能为小部分吸入的不溶性氧化铝提供长期隔离。
Radiolabeled 26Al inhalation studies were performed using tagged gamma aluminum oxide. The results showed that the material acted as an insoluble dust. about 45% was cleared from the lung after one day, with slow mechanical clearance from the lungs of the balance. After 72 days, only 0.2% of the alumina remained in the lung. The lung may provide long-term sequestration for small percentage of inhaled, insoluble alumina.

吸收、分配和排泄
调查人员评估了Sprague-Dawley大鼠在经气管内滴注氧化铝后的积累和清除情况。大鼠每周一次通过静电沉淀器获得的冶炼级氧化铝(MMAD=1.2微米)以1毫克/千克的剂量滴注,持续20周。在大鼠暴露期间定期处死一些大鼠,并在暴露后长达19周内进行观察。通过火焰和无火焰原子吸收光谱法测量铝。暴露大鼠在暴露期间持续积累铝,直至肺负荷达到约500微克铝/克组织。在暴露后19周内,只有9%的铝被清除。肺外组织,如大脑、骨骼、肾脏、肝脏和脾脏的铝含量与非暴露对照组动物(0.17-2.63微克铝/克组织)基本相同,但略有升高。
/Investigators/ evaluated the accumulation and clearance of aluminum oxide in Sprague-Dawley rats following intratracheal instillation. Rats were instilled with 1 mg/kg of smelter grade alumina obtained via electrostatic precipitator (MMAD = 1.2 um) once per week for 20 weeks. Groups of rats were sacrificed periodically during the exposure period and up to 19-weeks post exposure. Aluminum was measured by flame and flameless atomic absorption spectroscopy. Exposed rats steadily accumulated aluminum during the exposure period up to a lung burden of about 500 ug Al/g tissue.Only 9% was cleared during the 19-week post-exposure period. Extrapulmonary tissues such as brain, bone, kidney, liver, and spleen had aluminum levels that were essentially the same as, but slightly above, those of non-exposed control animals (0.17-2.63 ug Al/g tissue.

制备方法与用途

氧化铝简介

氧化铝是一种白色晶状粉末,具有多种晶体形态,常见的有α-Al₂O₃、β-Al₂O₃和γ-Al₂O₃。α-Al₂O₃比表面积较低,耐高温且化学性质稳定,但没有活性;而β-Al₂O₃和γ-Al₂O₃的比表面积较大,具有较高的孔隙率和耐热性,易于成型,并且具备较强的表面酸性和一定的碱性,因此广泛应用于催化剂及其载体。

产品特点

与其它材料相比,氧化铝拥有诸多独特而优良的特性。例如,它具有极高的熔点(2015℃)、良好的室温和高温强度、出色的化学稳定性和电绝缘性能、高硬度(莫氏硬度9)以及优异的耐磨性,且成本低廉。这些特点使得氧化铝适用于制造高速切削工具、高温热电偶套管、化工高压机械泵零件、内燃机火花塞、人工关节及航空磁流体发电材料等多样化的陶瓷器件。

纳米氧化铝材料则以其独特的光电特性、高磁阻现象、非线性电阻效应以及在高温下仍具有的高强度和高韧性、稳定性,在催化、滤光、光吸收、医药、磁介质及新材料等领域展现出广泛的应用前景。此外,各种纳米粉体材料的共有的小尺寸效应、表面界面效应、量子尺寸效应和宏观量子隧道效应也使得它们具有更加广阔的发展空间。

用途

氧化铝广泛应用于生产聚合氯化铝、硫酸铝以及油漆颜料、混凝土外加剂等。

同时,它还用于功能陶瓷、电子陶瓷、激光材料、吸附剂及层析等领域。
