When selecting high-temperature refractory mud at 1750°C,it is necessary to comprehensively consider the material composition,bonding performance,construction method,and specific application scenarios.Here are several types of refractory mud suitable for this temperature range and their characteristics for your reference:

1.High alumina refractory mud

Ingredients:Mainly composed of high-purity alumina or corundum powder(Al₂O∝≥70%),combined with refractory clay and binder.

characteristic:

High temperature resistance up to 1750-1800°C,good thermal shock resistance.

Suitable for masonry or repair of high alumina bricks and corundum bricks(such as kiln linings and high-temperature furnaces).

Recommended models:GL-80 or GL-90 high alumina clay(numbers represent the percentage of Al₂O3 content).

2.Silicon refractory mud

Composition:Mainly composed of silicon dioxide(SiO₂),with a small amount of flux added.

characteristic:

Acid resistant slag erosion,suitable for silicon brick masonry(such as coke ovens and glass kilns).

Under high temperature,it forms scale quartz,which enhances its strength,but has poor alkali resistance.

Attention:It is necessary to ensure that the expansion coefficient of silica bricks matches that of refractory mortar.

3.Jadeite refractory clay

Ingredients:fused alumina(Al₂O∝≥90%)or white alumina powder,combined with phosphate or silica sol.

characteristic:

The temperature resistance can reach over 1800°C,with high strength and strong corrosion resistance.

Suitable for extreme environments such as electric arc furnaces and ladle liners.

Disadvantages:High cost,construction requires specialized matching.

4.Zirconium containing refractory mud

Ingredients:High alumina or corundum based materials with added zirconia(ZrO₂).

characteristic:

Excellent stability at 1750°C and outstanding resistance to slag infiltration.

Suitable for high temperature areas with strong corrosiveness such as glass kilns and cement rotary kilns.

5.Phosphate bound refractory mud

Ingredients:High alumina aggregate+phosphoric acid or aluminum phosphate solution.

characteristic:

High bonding strength and good quick drying performance at medium and high temperatures(1600-1800°C).

Commonly used for hot repair or rapid cooling and heating environments.
