Aluminum and Aluminum Alloys Casting Problems

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...

Aluminum exclusion and aluminum tolerance in woody plants

The aluminum (Al) cation Al(3) (+) is highly rhizotoxic and is a major stress factor to plants on acid soils, which cover large areas of tropical and boreal regions. Many woody plant species are native to acid soils and are well adapted to high Al(3) (+) conditions. In tropical regions, both woody Al accumulator and non-Al accumulator plants occur, whereas in boreal regions woody plants are non...

Aluminum effects on calcium fluxes at the root apex of aluminum-tolerant and aluminum-sensitive wheat cultivars.

The role of Ca(2+) transport in the mechanism of Al toxicity was investigated, using a Ca(2+)-selective microelectrode system to study Al effects on root apical Ca(2+) fluxes in two wheat (Triticum aestivum L.) cultivars: Al-tolerant Atlas 66 and Al-sensitive Scout 66. Intact 3-day-old low-salt-grown (100 micromolar CaCl(2), pH 4.5) wheat seedlings were used, and it was found that both cultivar...

Perchlorate removal by acidified zero-valent aluminum and aluminum hydroxide.

Removal of perchlorate using either acid-washed zero-valent aluminum or aluminum hydroxide was studied in batch reactors under ambient temperature and pressure. Approximately 90-95% of perchlorate was removed within 24h in the presence of 35 g L(-1) aluminum at acidic pH (4.5+/-0.2). Although aluminum is a strong reductant, this study indicated no explicit evidence to support perchlorate reduct...
