Binder Burn Out
Binder burnout is a processing step that occurs before sintering, where the unfired or "green" body is heated until the polymer binder is burned out of the ceramic form. Polymers are often added to ceramic particles to promote higher densities and improved green strength.
Challenges
The green body, or pre-fired ceramic, must have sufficient strength to hold its shape after being pressed. It is also important to know how long the refractory needs to be held at a certain temperature to make sure all of the binder has volatilized.
Market
The market for this application is mostly industrial. Many companies that have a burnout stage in their process do not realize how useful our kilns can be and at lower initial and operating costs. L&L encourages anyone interested in using our products for this application to contact us.
Kilns
The size of the work required will dictate which kiln series applies to your process. For projects requiring longer hold times at hotter temperatures, you will want to consider a kiln with the quad element design and perhaps heavy-duty thermocouples. APM elements are also available as an upgrade for any of our kilns. For more information on these upgrades please search our information database on our website or contact and L&L technician.
