What is fireclay and what is fireclay used for? I believe you know nothing about fireclay like me before reading this article. However, after reading my introduction to refractory mud, I believe you will have an insight!


Refractory mortar is used to match refractory brick at any time. With such bonding method and masonry method, some customers will wonder why it is not necessary to use refractory cement for masonry? Isn't the refractoriness of refractory cement much higher than that of refractory mud? Isn't the setting strength of refractory cement higher than that of refractory mud? Yes, these questions are true. Let's get to know these two products.

Fireclay is also called fireclay or joint material (powder). Used as joint material for refractory masonry. It is composed of refractory powder and admixture. Almost all refractory materials can be made into powder used for preparing refractory mud. The ordinary refractory mud, which is made of refractory clinker powder and proper amount of binder, has low strength at room temperature, and has high strength only when ceramic bonding is formed at high temperature. The chemical bonded refractory mud, which takes the air hardening or thermal hard binding material as the binder, will produce a certain chemical reaction and harden before it is lower than the bonding temperature of the ceramic. The particle size of refractory mud varies according to the use requirements, and its limit particle size is generally less than 1 mm, some less than 0.5 mm or finer. The material of refractory slurry should be consistent with that of refractory products of masonry. In addition to being used as joint material, fireclay can also be used as protective coating for lining by coating or spraying. The main features are as follows: 1. Good plasticity and convenient construction; 2. High bond strength and strong corrosion resistance.
