Information

Cerium Fluoride CeF3 products, density: 6.9g/cm3 (cubic crystal), 6., melting point: 799℃, boiling point: 3426℃, expansion. Cerium Fluoride CeF3 products are one of the most abundant metal families in nature. Curved trim often sparkles. This kind of cloth is easily oxidized at room temperature and discolored easily in the air.

It can be scraped and burned in the air with a knife (pure decoration is not easy to spontaneously combust, but it is easy to spontaneously combust when slightly oxidized or alloyed with iron). When heated, it burns in the air to form oxides. It can react with boiling water and undergo a hydrogenation reaction. It is soluble in acid but not in alkali. Decorations can also be burned in halogens, such as in oxygen, to produce Cerium Fluoride CeF3 products.

At low temperature and high pressure, a magnetic material that is 18% higher than the ordinary type appears. Used to make flint, alloys, etc. Cerium Fluoride CeF3 products are the most active rare earth elements other than needles. It reacts slowly in cold water and accelerates in hot water. It is a silver-gray active metal, belonging to rare earth elements, periodic system III subgroup Gu series elements, the element symbol is CE, the powder is easy to spontaneously ignite in the air, and is soluble in acid and reducing agents.
