What is Ceramic Body Binder? Binders are glues that harden ceramic powders as they dry. They enable to improve surface adherence and slower drying. Mainly Binders are substances that improve the mechanical strength of green ceramic bodies so they can pass through production steps before firing and without breakage. What are the Purposes of using Ceramic Body Binder? Binders are basically glue, they are designed to harden and strengthen bodies and glazes as they dry. Ceramic Powders containing binders can exhibit remarkable surface adherence and durability on drying. Ceramic Powders containing binders can exhibit remarkable surface adherence and durability on drying. Binders are specially important in glazes, bonding them to even dense bisque surfaces.

In many cases, Binders addition to bodies are essential. Binders are used in ceramic industries to provide green strength so that the body will simply maintain its shape until it is sintered. In many cases, the green ceramic body has to be machined, inspected, stored and placed onto setters for firing, often by workers who are not perfectly careful, so considerable strength would have to be provided by the binder. What are the Negative Effects of Using a Ceramic Binder? Binders come at a cost. They can be very expensive. They slow down drying. They make slurries messy & difficult to process and handle. Cleanup is much more difficult. They generate carbon dioxide as they decompose during firing. In some industries like tiles, binders are avoided where possible or carefully chosen and monitored
