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 […]

Hliníková ocel vzniká po potažení oceli žárovým procesem slitinou hliníku a křemíku nebo komerčně čistým hliníkem, což nabízí mnoho výhod oproti oběma materiálům. Odolnost proti korozi je další z mnoha výhod, které práškové lakování ocelových povrchů nabízí. Kolem ní se vytvoří ochranná vrstva, která brání pronikání kyslíku a molekul vody do

Hliník je základním prvkem hliníku. Získává se z bauxitu (lateritového minerálu bohatého na hliník) pomocí Bayerova procesu. Ten zahrnuje rozpuštění minerálů obsahujících hliník v roztoku kaustické sody a následné vysrážení krystalů hlinitanu sodného z jejich roztoku. Hliníková keramika je hustý, dlouho se opotřebovávající materiál s vynikajícími elektrickými vlastnostmi. Používá se v trubkách, izolátorech a dalších průmyslových zařízeních.

Alumina boasts superior thermal and electrical insulating properties, making it suitable for high temperature environments such as those found in X-ray components, high voltage bushings, as well as special crucibles used in both metallurgical and chemical processes. Alumina can exist in several structural phases, but most often returns to its hexagonal alpha phase at elevated

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
