Sodium carbonate (Na2CO3) represent important ingredient of modern glass that adds both positive and negative features. It successfully lowers the melting point of silica to more manageable 1200 °C but it alsomakes the glass water soluble. To prevent glass from being water soluble and to increase its chemical structure, lime (calcium oxide, CaO), magnesium oxide (MgO) and aluminum oxide

pulverization of large particles using a ball or jet mill. Media milling involves the use of various milling media such as zirconia, and glass balls/beads to reduce the particle size of the compounds and produce sub-micron particle dispersions [5].

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

few phenols are soluble in water. Water-soluble compounds are tested with pH paper to see if they are acidic or basic. A pH of 4 or lower indicates a carboxylic acid. A pH of 8 or higher indicates an amine. Water-soluble compounds are tested with 5% sodium hydrogen carbonate (NaHCO 3) to determine whether or not they are carboxylic acids.
