Aluminium chloride - Wikipedia

2019-4-24 · Aluminium chloride (AlCl3), also known as aluminium trichloride, is the main compound of aluminium and chlorine. It is white, but samples are often contaminated with iron(III) chloride, giving it a yellow color. The solid has a low melting and boiling point. It is mainly produced and consumed in the production of aluminium metal, but large

A Short Review on Copper Calcium Titanate (CCTO

Abstract. Electroceramic calcium copper titanates (CaCu 3 Ti 4 O 12, CCTO), with high dielectric permittivities (ε) of approximately 10 5 and 10 4, respectively, for single crystal and bulk materials, are produced for a nuer of well-established and emerging appliions such as resonator, capacitor, and sensor.These appliions take advantage of the unique properties achieved through the

Specialty Chemicals – Welcome to Chivine

Soluble fluorides may react with water and form hydrofluoric acid. Alkaline earth metal-fluoride ion salts such as magnesium fluoride, tend to be mostly insoluble. Metal Oxides consist of a metal element and oxygen. They are typically basic and considered weak bases, water insoluble, and form salts in reaction to acid (acid-base reaction).
