A large portion of the lahar that abounds in Central Luzon is silicon dioxide (Si02) or silica. The same compound is utilized as raw material for silicon used in the manufacture of integrated circuits. However, it is best kept in mind that a purity level of at least 98.99 percent must be obtained in...
