Special Refractory Mortar is a high-temperature bonding material used for constructing and repairing refractory linings in industrial furnaces and thermal systems. It ensures strong adhesion between bricks, modules, and other refractory components, maintaining structural integrity under extreme heat and chemical exposure. As a global manufacturer and engineering solution provider, Cera Thermal (Jiangsu Cera Thermal Technology Co., Ltd.) delivers advanced mortar solutions designed to meet the demanding requirements of high-temperature operations across diverse industries.
Our Special Refractory Mortar is formulated for superior chemical resistance, thermal stability, and mechanical adhesion. Compared with conventional mortars, it maintains consistent bonding strength even under severe thermal cycling and corrosive atmospheres. The optimized particle distribution and binder system minimize shrinkage and ensure high bonding integrity during curing and service.
This chemical-resistant mortar performs exceptionally in glass furnaces, cement kilns, non-ferrous metal melting units, and petrochemical reactors where both heat and chemical exposure are intense. Its thermal shock resistance helps prevent cracks and extends the service life of refractory linings.
We offer a wide range of refractory mortar formulations to meet varied industrial needs. Each type is developed through advanced R&D to ensure compatibility with different refractory bricks and lining systems.
| Type | Main Composition | Key Features | Typical Applications |
|---|---|---|---|
| High-Alumina Mortar | Al2O3-based | Excellent bonding strength and high refractoriness | Cement kilns, metallurgical furnaces |
| Silica-Based Mortar | SiO2-rich | High-temperature resistance and good thermal expansion match | Glass furnaces, coke ovens |
| Chemical-Resistant Mortar | Special additives | Superior corrosion resistance in acidic or alkaline atmospheres | Petrochemical reactors, incinerators |
In addition to standard grades, we develop custom refractory mortars for unique furnace designs, operating atmospheres, or installation conditions. Our R&D team works closely with clients to achieve optimal performance and cost efficiency.
Special Refractory Mortar is widely applied across high-temperature industries to bond and seal refractory linings. Its durability and versatility make it essential in thermal system construction and maintenance.
Glass furnaces and regenerators
Cement rotary kilns and preheaters
Petrochemical reactors and reformers
Thermal oxidizers and incineration systems
Non-ferrous metal smelting and heat-treatment furnaces
By ensuring consistent bonding and minimizing heat leakage, this mortar improves energy efficiency and extends lining service life, reducing maintenance downtime and operational costs.
Our Special Refractory Mortar stands out for its material quality, engineering precision, and reliable performance. As a global manufacturer and EPC solution provider, we integrate material production, design, and installation services into one complete system.
Superior bonding strength and durability under high thermal loads
Resistance to chemical corrosion and thermal shock

Proven EPC experience with more than 1000 projects globally
These strengths make our mortars a trusted choice for industries seeking long-term reliability and performance stability.
Selecting the right mortar formulation requires consideration of several operational factors. The table below provides general guidance for matching mortar types to application conditions:
| Operating Temperature | Atmosphere | Recommended Mortar Type |
|---|---|---|
| Up to 1400°C | Oxidizing | Silica-based mortar |
| 1400–1700°C | Neutral or reducing | High-alumina mortar |
| Up to 1500°C | Chemically aggressive | Chemical-resistant mortar |
For the best installation results:
Ensure substrates are clean and slightly damp before application.
Mix thoroughly to achieve uniform consistency.
Apply thin, even layers to minimize shrinkage during drying.
Follow recommended curing and drying schedules before furnace operation.
