The tests to be made are those given under Sodium Borate, Purest, Cryst. But for each gram of the crystallized borax use 0.5 gm. of the fused. 

Boron is (1) a yellowish-brown crystalline solid and (2) an amorphous greenish-brown powder. Both forms are unaffected by air at ordinary temperatures but when heated to high temperatures in air form oxide and nitride. Crystalline boron is unattacked by HC1 or HNO3, or by NaOH solution, but with fused NaOH forms sodium borate and hydrogen reacts with magnesium but not with sodium.

Borax pentahydrate (also known as Neobor ) is the most common form of sodium borate used in a variety of industries. Its advantages when compared with borax lie in the lower transportation, handling, and the storage cost of a more concentrated product. Borax pentahydrate readily effloresces upon heating. It starts to dehydrate at about 65°C, loses all water of hydration when heated above 320°C, and fuses when heated above 740°C. In water, it hydrolyzes to give a mildly alkaline solution with excellent buffering properties.7...

Farina et have used both CE and HPLC for the determination of Ceftazidime (cephalosporin antibiotic) and its degradation products. The CE separation was performed using a micellar media. Specifically, separation was achieved using a 64.5-cm (56-cm effective length) x 50- JLm fused-silica capillary with extended light path, a buffer consisting of 25 mM sodium borate, pH...

FIGURE 2.6 Analysis of PSA heterogeneity by CZE. The analytical system included a Model 310 Thermo Capillary Electrophoresis Crystal CE instrument operated in normal polarity at 25 kV with UV detection at 214 nm. Free PSA isoforms were separated on the basis of m/z using a 60 cm long by 50 jim ID fused-silicacapillary. Separation media contained 20 mM sodium borate, 5 mM 1,3-diaminopropane, pH 8.0. Samples were pressure injected for 3 s at 200 mbar. Panels (a)-(d) show the separation of PSA isoforms in purified PSA obtained from four different commercial vendors.

Sodium Borates (11). These water-soluble salts, made by U.S. Borax and others, have been known since the eighteenth century as nondvu-able flame retardants for cotton, rope, canvas, and paper. The hydrated salts can act as endothermic heat sinks and moreover the salt fuses to a nonflammable glassy barrier layer. Sodium borates, in particular borax (sodium tetraborate decahydrate [1303-96-4]), are used in disposable paper and nonwoven cellulosic products, and as wood flame retardants where their water solubility can be tolerated. The borate salts are effective on flaming combustion but allow severe afterglow they are best used in formulations with afterglow preventatives, and often used with boric acid.
