High Thermal Conductivity insulation 95% alumina ceramic plate
1. Description of Alumina ceramic plate
Aluminium oxide (British English) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-Al2O3 as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. Al2O3 is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature.
1). Excellent insulation, security, long working life.
2). High temperature resistance
3). Resistance to electric breakdown
4). Stand wear and tear
5). High strength
6). Corrosion resistance
7). Good compactness
8). HIgh hardness

1. Alumina ceramic products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling and cleaning
2. Check whether any micro-cracks exist before using alumina ceramic products. Products with micro-cracks should not be used.
3. Alumina ceramic products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them.
