Calcined baryta

Barium Oxide (Barium Monoxide, Baryta, Barium Protoxide, Calcined Baryta). BaO, mw 153.36 colorl or white to yelsh-white deliq powd mp 1923°, bp 2000°, d 5.72g/cc. Sol in dil acids, ethanol, methanol and w (decomps with a large amt of heat being evolved). Prepn is by thermal decompn of BaCOj under high vacuum. It is a product of the burning of the many barium compds present in pyrots and, as discussed above, it is used as an anti-barrel wear additive in proplnt compns... [Pg.449]

Oxids.—Barium Monoxid—Baryta—BaO—152.8—is prepared by calcining the nitrate. It is a grayish-white or white, amorphous, caustic solid. In air it absorbs moisture and COa, and combines- with HiO as does CaO. [Pg.203]

The most commonly employed fillers in plasticized PVC are the precipitated forms of calcium carbonate (CaCOy) and related minerals such as dolomite (calcium magnesium carbonate). CaCOj fillers are diroated with fatty acids to improve physical properties of PVC, particularly flex life and elongation at break. The effect of calcium carbonate fillers on fusion properties of PVC is reviewed (47). Other fillers include china clay, calcined clay, asbestos, barytas, talc, alumina and kieselguhr and silicates. Micaceous-talc fillers in PVC which are polyblended with acrylonitrile rubber shows an extraordinary effect. Small amounts improve elongation and energy to break. [Pg.56]
