Foam Ceramic Plate – High-Performance Filtration & Thermal Insulation Material

Introduction:
Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses . With their excellent thermal shock resistance and corrosion resistance from molten aluminum, they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

Size available:
7", 9", 12", 15", 17", 20", and 23", with porosities from PPI 10 to PPI 60(PPI ie pores per inch).
Other special sizes could be produced on request.

Quick Details

Foam Ceramic Plate – High-Performance Filtration & Thermal Insulation Material

The Foam Ceramic Plate is a porous ceramic material with a high-strength, lightweight structure. It is widely used in metal filtration, thermal insulation, and environmental protection applications due to its excellent high-temperature resistance, chemical stability, and filtration efficiency.

Key Features & Advantages:

High Porosity & Permeability

Provides efficient filtration by trapping impurities and inclusions in molten metal and gases.

Excellent Thermal Shock Resistance

Withstands sudden temperature changes without cracking, making it ideal for high-temperature environments.

Superior Mechanical Strength

Durable and resistant to mechanical stress and deformation during use.

Good Chemical Stability

Resistant to corrosion by acids, alkalis, and molten metals, ensuring long service life.

Lightweight & Energy-Saving

Low density reduces overall weight, improving thermal efficiency and energy savings.

Applications of Foam Ceramic Plate:

Molten Metal Filtration

Removes inclusions and impurities from aluminum, steel, iron, and copper in casting industries.

Thermal Insulation & High-Temperature Applications

Used in kilns, furnaces, and combustion chambers for heat conservation.

Environmental Protection & Air Purification

Applied in catalyst supports, exhaust gas filtration, and industrial waste treatment.

Chemical Processing

Used as porous carriers for chemical reactions and gas separation.
