酸化ベリリウム 化学特性,用途語,生産方法

説明

Beryllium oxide (BeO) is formed by the ignition of beryllium metal in an oxygen atmosphere. The resulting solid is colourless and insoluble in water.

化学的特性

solid

物理的性質

Beryllium oxide (BeO) is a white crystalline oxide. It occurs in nature as the mineral “Bromellite”. Historically, beryllium oxide was called glucina or glucinium oxide. It is an electrical insulator and its thermal conductivity is such that it is higher than any other nonmetal except diamond, and actually exceeds that of some metals. Its high melting point leads to its use as a refractory.

使用

manufacture of beryllium oxide ceramics, glass; in nuclear reactor fuels and moderators; catalyst for organic reactions.

使用

Beryllium oxide is used in many high-performance semiconductor parts for applications such as radio equipment because of its good thermal conductivity while also being a good electrical insulator. It is used as a filler in some thermal interface materials such as “THERMAL GREASE”.Some high-powered semiconductor devices have used beryllium oxide ceramic between the silicon chip and the metal mounting base of the package in order to achieve a higher degree of thermal conductivity than for a similar construction made with Al2O3. It is also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons and gas lasers. Beryllium oxide (BeO) is a space age technical ceramic material that offers a combination of desirable properties not found in any other material.

定義

ChEBI: A beryllium molecular entity consisting of beryllium (+2 oxidation state) and oxide in the ratio 1:1. In the solid state, BeO adopts the hexagonal wurtzite structure form while in the vapour phase, it is present as discrete diatomic covalent molecules.

製造方法

Beryllium oxide can be prepared by calcining beryllium carbonate, dehydrating the hydroxide or igniting the metal with oxygen gas, as shown in the following reactions:
BeCO3→BeO+CO2
Be(OH)2→BeO+H2O
2Be+O2→2BeO
Igniting beryllium in air

一般的な説明

Odorless white solid. Sinks in water.

空気と水の反応

The amount of heat generated by hydrolysis may be large.

反応プロフィール

BERYLLIUM OXIDE is incompatible with the following: Acids, caustics, chlorinated hydrocarbons, oxidizers, molten lithium, magnesium .

危険性

Highly toxic by inhalation. Keep container tightly closed and flush out after use.

健康ハザード

Any dramatic, unexplained weight loss should be considered as possible first indication of beryllium disease. Other symptoms include anorexia, fatigue, weakness, malaise. Inhalation causes pneumonitis, nasopharyngitis, tracheobronchitis, dyspnea, chronic cough. Contact with dust causes conjunctival inflammation of eyes and irritation of skin.

火災危険

Special Hazards of Combustion Products: Toxic BERYLLIUM OXIDE fume may form in fire.

工業用途

A colorless to white crystalline powder of the composition beryllium oxide, also called beryllia. It has a specific gravity of 3.025, a high melting point, about 2585 C, and a Knoop hardness of 2000. It is used for polishing hard metals and for making hot-pressed ceramic parts. Its high heat resistance and thermal conductivity make it useful for crucibles, and its high dielectric strength makes it suitable for high-frequency insulators. Single-crystal beryllia fibers, or whiskers, have a tensile strength above 6800 MPa.
Beryllium oxide is tapped for nuclear reactor service because of its refractoriness, high thermal conductivity, and ability to moderate (slow down) fast neutrons. The thermal neutrons that result are more efficient in causing fusion of uranium- 235. Nuclear industry uses for beryllia include reflectors and the matrix material for fuel elements. When mixed with suitable nuclear poisons, beryllium oxide may be a new candidate for shielding and control rod assembly applications.
