The invention relates to a detection apparatus for detecting particles, wherein the detection apparatus comprises a detection surface for detecting particles on the detection surface and wherein the detection surface comprises protrusions for limiting a movement of the particles. The composition of matter consists of standard novalac resins with the hexa component replaced by solid granular resole or curing agent. Reading of the beads is facilitated by restraining the beads in arrays, andor using a focused laser. If further error recovery is needed on the track, a subsequent read operation may then be performed. The invention particularly relates to an improved process for the production of ceramic tiles using industrial wastes such as iron ore slime, fly ash and blast furnace slag. The negative electrode includes an aluminum alloy powder as an active material,.
