Several different standards have been established for grit size.

Silicon carbide, SiC (carborundum) is a hard, high melting solid and a well known abrasive.

Cohenite is a naturally occurring iron carbide mineral with the chemical structure (Fe, Ni, Co)3C.

These standards establish not only the average grit size, but also the allowable variation from the average.

The mineral form of silicon carbide was named moissanite in honor of Moissan later on in his life.

This is the first time that the plutonium rich carbide fuel has been reprocessed anywhere in the world.

And if you want an example of perseverance, grit and strength in a beautiful, little package, it is her.

At first, he mistakenly identified the crystals as diamonds, but in 1904 he identified the crystals as silicon carbide.

Boron carbide, B4C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms.

There is a staff on the boat called carbide fitter, who is responsible to replace sulfur rock and control the volume of water to generating acetylene gas.

In 1898 Adolph Frank and Nikodem Caro decoupled the process and first produced calcium carbide and in a subsequent step reacted it with nitrogen to calcium cyanamide.

British resistance to grand European plans is the democratic grit in an enterprise that could become authoritarian, despite having the best intentions, and should serve as a necessary corrective to the utopianism of the technocrats.

Exercising any muscle for the first time takes dedication and grit, and it didn t take me long to realize that along with a civics program in schools, this country also needs better journalists and reporters.

SINGAPORE The industries of the future will require people creative and innovative enough to work with technology, not be replaced by it. And workers will need resilience and grit, because failure, more often than not, is part of the innovation process.

The indigenously developed unique plutonium rich mixed carbide fuel used in the fast breeder test reactor (FBTR) has performed extremely well, having operated past a burn up of 148,000 megawatt day per tonne (MWd t) without a single fuel pin failure.

But when we fail to give our best, we simply haven't met the test, of giving all and saving none until the game is really won of showing what is meant by grit of playing through when others quit of playing through, not letting up.

The coal comes from Colombia, and costs 300 per ton if Antillana had been able to negotiate with United States manufacturer UCAR, from which it would be able to get the world's best carbide graphite electrode, that raw material would be obtained free, because of the contract undertakings UCAR has with its purchasers.
