Boron Properties At Room Temperature

The temperature at which the liquid gas phase change occurs.

Boron properties at room temperature.

At room temperature it is a poor electrical conductor but it is a good conductor at high temperatures. Elemental boron transmits portions of infrared light. It is a metalloid with a standard atomic weight of 10 811. Boron oxide b 2 o 3 is used in glassmaking and ceramics.

Boron does not react with air at room temperature but at higher temperatures it burns to form boron trioxide. The boron mineral ulexite exhibits natural fiberoptic properties. Boron 10 one of the naturally occurring isotopes of boron is a good absorber of neutrons and is used in the control rods of nuclear reactors as a radiation shield and as a neutron detector. Boron is capable of forming stable covalently bonded molecular networks.

Boron filaments are used in the aerospace industry because of their high strength and lightweight. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. Boron has interesting optical properties. Boron is used to dope silicon and germanium semiconductors modifying their electrical properties.

Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase. The physical properties of boron depend on its allotrope. Boron carbide is used to make armored vehicles because of its strength. Boron forms several commercially important compounds.

4 b 3 o 2 2 b 2 o 3 ball and stick model of tetraborate anion b 4 o 5 oh 4 2 as it occurs in crystalline borax na 2 b 4 o 5 oh 4 8h 2 o. It is solid at room temperature with a melting point of 3769 f 2349 k and a boiling point of 7101 f 4200 k at atmospheric pressure.
