Boron trioxide B2O3 is the only known oxide of boron; and may be prepared by heating amorphous boron in oxygen, or better, by strongly igniting boric acid.

The products are phenol and pyrocatechol, with some quantity of an amorphous product probably formed by condensation of a quinone with the phenolic products of reaction.
And such in reality was their fear, when, after hours spent in fruitless wandering, they stood holding each other's hands, crouching and cowering together in the midst of that amorphous darkness!
He often uses such expressions as these, "So they chanced to come together," and describes the amorphous condition of the first organisms in a way that makes one think he fancied a perfectly chaotic origin.
Crucibles require coarsely crystalline graphite, but pencils, lubricants, and foundry facings may use amorphous and finely crystalline material.
A large part of the world's needs of crucible graphite will probably continue to be met from Ceylon and Madagascar, while a large part of the amorphous graphite will come from the four sources mentioned.
Chalk is a soft amorphoussubstance of the same composition as limestone.
The most important use of amorphousgraphite is for foundry facings, this application accounting for about 25 per cent of the total United States consumption of graphite of all kinds.
Artificial graphite, in amounts about equal to the domestic production of amorphous graphite, is produced from anthracite or petroleum coke at Niagara Falls.
Amorphous graphite is formed in many places where coal and other carbonaceous materials have undergone extreme metamorphism.
The proof in this case has been carried a step further, for the active juice obtained by grinding such acetone-yeast, when precipitated with alcohol and ether, yields an amorphous powder, still capable of fermenting sugar.
It is a brownish amorphous solid, which is insoluble in water.
They also contain about 14% of a red, amorphous tonic material which, after drying, is but slightly soluble in cold or hot water.
Papain is an amorphous substance, perfectly white, soluble in water, insipid, odorless.

Jacobs analyzed the bark and isolated anamorphous resin of yellowish color and very bitter taste.
It seemed to go on for ever in a most barbaric and amorphous din; with corybantic crashings, with brazen fanfares and stinging cymbals it flung itself against the audience, while the woodwind howled and the violins were harsh as cats.

We see in how broad a sense should be understood the relativity of space; space is in reality amorphous and the things which are therein alone give it a form.
And then comes a question: Is not this amorphous continuum, that our analysis has allowed to survive, a form imposed upon our sensibility?
From this amorphous continuum can therefore arise indifferently one or the other of the two spaces, just as on a blank sheet of paper may be traced indifferently a straight or a circle.
Glass is an unstable form of mineral matter; and every species of glass, including obsidian, tends with the lapse of time to become crystalline or stony, the amorphous changing to the felsitic structure.
Obsidian is, in fact, simply rhyolite or trachyte which, cooling quickly, has not had time to crystallize, but has remained permanently in the amorphous or glassy state.
In other words, it is not truly crystalline or stony, and yet it is just as clearly not amorphous or glassy.
They are formed of a sort of animated jelly, amorphous and diaphanous, and have received from Dujardin the name of Sarcoda, or soft-fleshed animals.
