High-temperature, energy-efficient ceramic coatings for refractories—no longer “theoretical” technology—are being used successfully in kiln and furnace applications to reduce energy consumption, improve temperature uniformity, reduce maintenance, and increase production while improving product quality.

Factors to Consider in Ceramic Drying and Firing

Problems ranging from simple cracking to catastrophic steam explosions can occur if ceramic products are not dried uniformly.

Drying is a necessary step in the processing of all ceramic products and components, whether it takes place as a separate step or is a preliminary step in the firing process. Ceramics are made from different combinations of materials that can be in slurry form or even more liquid, in the case of slip-cast ware at the start of the fabrication process.

What You Need to Know About NFPA 86-2015
