1. Product Introduction
Lightweight insulating diatomite bricks are high-performance refractory materials made from natural diatomaceous earth, processed to achieve superior thermal insulation and low thermal conductivity. These bricks are ideal for applications requiring energy efficiency and heat retention in high-temperature environments, such as industrial furnaces, kilns, and boilers.
