Aluminum oxide alumina, commonly referred to as alpha-alumina, is one of the main materials used in producing technical ceramics. It’s hard, wear-resistant, and offers protection from strong acids. Corundum has an extremely high melting point and is odorless; naturally occurring as corundum (red), ruby (pink), or sapphire (blue). Its crystal structure consists of hexagonally packed […]

L'acciaio alluminato si ottiene rivestendo l'acciaio, tramite un processo di immersione a caldo, con una lega di alluminio e silicio o con alluminio commercialmente puro, offrendo numerosi vantaggi rispetto a ciascuno dei due materiali considerati singolarmente. La resistenza alla corrosione è un altro dei numerosi vantaggi offerti dal rivestimento in polvere per le superfici in acciaio. Intorno ad esso si forma uno strato protettivo che impedisce alle molecole di ossigeno e acqua di penetrare

L'allumina è il componente principale dell'alluminio. Per estrarla dalla bauxite (un minerale lateritico ricco di alluminio), si ricorre al processo Bayer. Questo processo prevede la dissoluzione dei minerali contenenti alluminio in una soluzione di soda caustica, seguita dalla precipitazione di cristalli di alluminato di sodio dalla soluzione stessa. Le ceramiche a base di allumina sono materiali densi e resistenti all’usura, dotati di eccezionali proprietà elettriche. Sono utilizzate in tubi, isolanti e altri prodotti industriali

L'allumina vanta eccellenti proprietà di isolamento termico ed elettrico, che la rendono adatta ad ambienti ad alta temperatura, come quelli presenti nei componenti per raggi X, nei passanti ad alta tensione e nei crogioli speciali utilizzati nei processi metallurgici e chimici. L'allumina può presentarsi in diverse fasi strutturali, ma molto spesso ritorna alla sua fase alfa esagonale a temperature elevate

Aluminum (Al) is the third most abundant element on Earth and its compounds have long been utilized by humanity since antiquity. Ancient Greeks used alumen as both an astringent and medicinal remedy; additionally it served as a mordant when dyeing fabric. Pure aluminum is soft, lightweight, and conducts electricity efficiently, as well as being highly

Due to its low vapor pressure and solubility in many chemicals, alumina is widely utilized in electrical applications. Furthermore, its superior corrosion-resistance makes it an invaluable material. Aluminum conducts electricity quite readily when in its raw state; however, surface treatments such as coating and anodizing can decrease conductivity, while paints or other finishes can have

Activated alumina’s porous structure and expansive surface area enable it to trap moisture and contaminants efficiently, an attribute which makes it especially valuable in industries such as pharmaceuticals and electronics, where moisture-related problems such as corrosion or malfunction can have major repercussions for products and processes. Whenever handling activated alumina, be sure to wear appropriate

The aluminate phase comprises up to 11% of total cement volume and helps contribute early strength. Unfortunately, its resistance to sulfate attack and hydraulic properties are poor; increasing its content reduces set time and heat of hydration but does not improve sulfate resistance. Al is typically coordinated to four, five, or six oxygen atoms in

Young’s modulus aluminas are widely utilized engineering applications. Their elastic properties can be accurately assessed using non-destructive Sonelastic Systems testing at room temperature as well as low and high temperatures, for a complete characterisation. Tensile tests are an efficient and straightforward method for gathering young’s modulus data, subjecting samples gradually to increasing tension until their
