Product Detail


Ceramic Substrates made of Al2O3 Alumina is much cheaper than AlN Aluminum Nitride Substrates. Alumina Substrates / Sheets / Plates are made by tape casting and dry pressing. Tape casting is suitable for producing thin Ceramic Substrates, dry pressing is suitable for producing thick Ceramic Substrates. General purity degrees of Al2O3 Substrates / Sheets / Plates are 96%, 99% and 99.5%. Standard thickness of Al2O3 Substrates / Sheets / Plates ranges from 0.2mm to 2.0mm, however, customized sizes are available. UNIPRETEC is also capable to do laser scribing, surface grinding, polishing and other machining work.

  • Ceramic Welding Roll

    Ceramic Si3N4 Welding Rolls for Steel Tube Industry

    silicon nitride ceramics is an inorganic non-metallic material. It is a super-hard material, which has lubricity and is wear-resistant; except for hydrofluoric acid, it does not react with other inorganic acids. It is highly corrosive and resistant to oxidation at high temperatures. Moreover, it can resist high thermal shocks. It will not crack when heated to over 1,000°C in the air, cooled rapidly and then heated rapidly. Because of the excellent characteristics of Si3N4 ceramics, it’s often used to manufacture bearings, turbine blades, mechanical seal rings, permanent molds and other mechanical components. In the field of welding of copper stainless, and aluminum tubes, silicon nitride ceramic rolls have natural advantages.
