Polished Ultra Thin Ceramic Sheet / Ceramic Disc Thickness 0.2 mm
Alumina (Al2O3) has a wide application due to its versatility and
low material cost. Alumina possesses a high melting point, strong
hardness, and good chemical stability, making it a good material to
withstand high temperature and chemical corrosion.Thin Ceramic Sheet / Ceramic Disc are available in different dimensions and thicknesses. Call for
custom shapes and sizes.
Alumina Sheet with properties of insulation, thermal conductivity
and breaking strength. Moreover, one of the unique properties is
its surface roughness. Mingrui provide Thin Ceramic Sheet / Ceramic Disc which is excellent in adhesion with a thin film and thick film
metalization due to fine particles.
■Good smoothness / flatness with less porosity. Excellent in
adhesion with thin film and thick film materials.
■Less variance in outline, plate thickness, slit pitch, etc.
■Minimal warpage, bending, and undulation.
■Physical and chemical properties are stable even under a hot
environment. Excellent in thermal shock resistance. High thermal
conductivity and coefficient of thermal expansion similar to that
■Superior mechanical strength. Products with higher mechanical
strength are also in our lineup.
■Excellent resistance against oil and chemical.
■Excellent in insulation properties, high dielectric breakdown
voltage, high surface resistivity / volume resistivity, and small
■Stable breaking strength, and less variance in shape or
■The high reflective substrate, especially suitable for optical
applications such as LED, is also available.
Applications of Thin Ceramic Sheet / Ceramic Disc :LED packages, Thin Ceramic Sheet / Ceramic Disc for chip resistors, HIC substrates for heat dissipation, Power
modules, FAX substrates for thermal printer head
*Various processing is available (thin film metalization, thick
film metalization, glaze, etc.)
This Thin Ceramic Sheet / Ceramic Disc is characterized by its extremely high strength and thermal
conductivity. The outstanding surface quality on both sides makes
it the perfect companion for any commercial thick film paste and
even makes it suitable for a number of thin film applications
With its extremely fine surface quality, Thin Ceramic Sheet / Ceramic Discis designed especially to meet the highest demands in thin-film
Thin Ceramic Sheet / Ceramic Discoffers consistently reliable and convincing performance even when
subject to high thermal and electrical loads in terms of its:
Thermal shock resistance

Description of Thin Ceramic Sheet / Ceramic Disc:
Alumina substrates can withstand high temperature and maintain high
strength and hardness. Alumina plates also have superb performances
in electrical insulation, high chemical resistance and low thermal
expansion. We have various sizes of semi finished shapes in stock
and are able to conduct custom manufacturing for all kinds of
Thin Ceramic Sheet / Ceramic Disc Specifications
1. material : Alumina ceramic
2. Very small and very large size can be made
3. High temperature, good abrasive.
Refractory alumina ceramic substrate/ceramic plate is our main
product.Misson can supply high quality alumina plates with
Very small and very large sized plates can be made.
Fine grinding can made tight tolerance.
High temperature and abrasive resistance is good
1. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Alumina eramic is the material of choice
for wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
Alumina ceramic is the most mature of the engineering ceramics,
offering excellent electrical insulation properties together with
high hardness and good wear resistance,but relatively low strength
and fracture toughness.Alumina ceramics are generally white but may
also be pink or ivory.The color is derived from either the
sintering additives or impurities in the raw materials.
