Boric Oxide. Boric oxide, formula wt 69.62, is the only commercially important oxide. It is also known as diboron trioxide, boric... [Pg.189]

But all these parameters are also sensitive to the presence of other compounds. Therefore, the AIT of ethylene is lower when the walls of a reactor are covered with diboron trioxide. [Pg.241]

Boric Oxide. Boric oxide, B203, formula wt 69.62, is the only commercially important oxide. It is also known as diboron trioxide, bone anhydride, or anhydrous boric acid. B203 is normally encountered in the vitreous state. This colodess, glassy solid has a Mohs hardness of 4 and is usually prepared by dehydration of boric acid at elevated temperatures. It is mildly hygroscopic at room temperature, and the commercially available material contains ca 1 wt % moisture as a surface layer of boric acid. The reaction with water ... [Pg.189]

Diboron trioxide can be used to prepare low temperature glazes because its melting point is about 600°F. [Pg.156]

When diboron trioxide is added to a glaze preparation having a slight amount of iron oxide, the resulting glaze may be milky or an opalescent blue. [Pg.166]

Write the chemical formula for each of the following compounds (a) diboron trioxide, (b) dinitrogen pentasulfide, (c) phosphorus triiodide, (d) sulfur tetrachloride, (e) silicon sulfide, (f) hydrogen sulfide, (g) tetraphosphorus hexoxide. [Pg.173]

Write the chemical formula for each of the following compounds (a) diboron trioxide, (b) dinitrogen pentasulflde,... [Pg.173]

Used in production of boron, heat-resistant glassware, fire-resistant additive for paints, electronics, liquid encapsulation techniques, herbicide. White crystals mp = 450° bp = 1860° d = 2.46 soluble in H2O (3 g/100 ml) LDso (mus orl) = 3163 mg/kg. Atomergic Chemetals Lancaster Synthesis Co. Noah Chem. u.S. Borax Inc. [Pg.78]

Other methods of preparing trialkylborons are by treatment of trialkylaluminums or dialkylzincs with boric triesters,209 metaboric ester (RB02) ,210 or mixtures of boric esters and diboron trioxide.211... [Pg.778]

Elemental boron is produced in one industrial process by heating diboron trioxide with magnesium metal, also producing magnesium oxide. Write the unbalanced chemical equation for this process. [Pg.234]

Ethylboronic acid can be prepared from chloroethylphenylborane, diethyl ethylboronate, or triethylboroxin." Very impure products resulted from the hydrolysis of the products obtained when trimethyl borate was reacted with bromoethylmagnesium. Ethylboronic acid is best prepared by the reaction of triethylboroxin with water. Triethylboroxin is easily obtained from diboron trioxide with triethylborane or from tetraethyldiboroxane either thermally or by /BH catalysis. ... [Pg.84]

When elemental boron, B, is burned in oxygen gas, the product is diboron trioxide. If the diboron... [Pg.162]

Boronitride (BN)n, on the other hand, forms a parquet polymer, very stable to oxidation and hydrolysis. It can be used up to about 2 000 C. To produce it, fibers of diboron trioxide are first formed and these are then converted to white boronitride with ammonia ... [Pg.600]
