Lightweight fireclay insulating brick (Al₂O₃≥35%, 1250℃ max, bulk density 0.6-1.0 g/cm³, conductivity ≤0.35 W/(m·K)) is an economical, stable insulator.
| Al₂O₃ Content | ≥35% |
|---|---|
| Max. Service Temp. | 1250℃ |
| Bulk Density | 0.6-1.0 g/cm³ |
| Thermal Conductivity | ≤0.35 W/(m·K) |
Lightweight fireclay insulating bricks are economical fired insulation: Al₂O₃ ≥35%, max service 1250℃, bulk density 0.6-1.0 g/cm³ and thermal conductivity ≤0.35 W/(m·K) at 500℃. Economical with stable insulation, they suit large-area insulation of boilers, flues and pipes. It is Henan Songrui's cost-effective general insulation grade.
Use below 1250℃ for insulation, never load-bearing or slag contact; lay in layers with dense working linings. Choose lightweight high-alumina for higher temperatures.
Lay in layers with dense linings; use lightweight insulating mortar with stable layer bonding.

Lightweight fireclay insulating brick is economical for medium-low temperature insulation:
About 1250℃ for medium-low temperature insulation.
Below 1250℃, fireclay is more economical; choose high-alumina for higher temperatures.
Typically 0.6-1.0 g/cm³—light and insulating.

Light mullite insulating brick takes mullite as its main phase with Al₂O₃ of 50%–85%, featuring low thermal conductivity, low bulk density and good high-temperature structural strength for insulating and composite linings of ceramic kilns, glass furnaces and reheating furnaces.
Alumina bubble brick is made from fused alumina bubbles with high-purity alumina matrix, serving at 1600-1800°C with low thermal conductivity, good strength and direct flame contact for high-temperature kiln insulating and working layers.
Lightweight high-alumina insulating brick (Al₂O₃≥48%, 1500℃ max, bulk density 0.8-1.2 g/cm³, conductivity ≤0.5 W/(m·K)) saves energy with light weight and low thermal conductivity.
Lightweight silica brick (SiO₂≥92%, 1550℃ max, bulk density 1.2-1.5 g/cm³, RUL ≥1550℃) combines silica refractoriness with lightweight insulation and matches silica brick thermal expansion.
