Other materials, such as garnet, silicon carbide (SiC), and boron carbide (B 4 C), are also used, depending on costs and the optical materials being processed. Using them involves mixing the abrasive particles with a liquid vehicle and a suspension agent that evenly distributes the abrasive over the lap plate and reduces settling, thereby aiding in the effectiveness of recycling of the slurry.
