Technical Ceramics
Ceramic Substrates are mainly made of Alumina(Al2O3) and Aluminum Nitride(AlN). Tap casting and dry pressing are two main producing methods. Al2O3 is cheaper and more widely used than AlN. Purity of Aluminum Nitride is 99%, Alumina's purity degrees range from 96% to 99.5%. UNIPRETEC is good at stably and fast supplying qualified Alumina Substrates and Aluminum Nitride Substrates, we are also capable to do laser scribing, surface grinding, polishing and other machining work. Typical applications of Ceramic Substrates are: LED packages, Power modules, Substrate for chip resistors, HIC substrates for heat dissipation, FAX substrates for thermal printer head, Substrates for automotive parts, Substrates for general thick film application, Substrates for sensor parts, Substrates for electronic devices...

  • 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.

  • boron nitride setters

    Ceramic Boron Nitride Setters for Nitride Ceramics Sintering

    Boron Nitride can be compared to graphite thanks to lubrication capacities, good thermal conduction and easy machinability, although it's white and has good electrical insulation. Plus, it isn't wetted by most molten metals and can therefore be used as a container for most molten metals.

  • Alumina ceramic sintering aid for MIM

    High Purity Alumina Ceramic Sintering Aid for MIM Components

    Ceramic kiln furniture has two basic properties - firstly dimensional stability at high temperatures and secondly thermal shock resistance. UNIPRETEC is professional manufacturer of High Purity Alumina Ceramic Kiln Furniture(Trays, Setter Plates, Saggers).

  • Ceramic Rollers for Laboratory Three Roll Mill

    Al2O3 Si3N4 ZrO2 Ceramic Rollers for Laboratory Triple Three Roll Mill

    UNIPRETEC provides ceramic rollers for laboratory three-roll grinders. UNIPRETEC's rollers are made of special ceramic materials, including high-purity alumina, zirconia and silicon nitride.

  • Si3N4 Silicon Nitride Ceramic Bearing Balls UNIPRETEC

    Si3N4 Silicon Nitride Ceramic Bearing Balls

    The unique combination of material properties of Silicon Nitride makes it ideal for applications with high dynamic stresses, thermal rigor, and demanding reliability requirements, meanwhile, it provides advantages in severe-service applications such as turbines and high-end ball bearings.

  • zirconia sheet

    YSZ ZrO2 Yttria Stabilized Zirconium Oxide Zirconia Ceramic Crucible

    Zirconium dioxide, also known as zirconia and zirconium oxide, is a crystalline metal oxide that has found its way into the technical advanced ceramics industry. It is characterised by its high thermal resistivity, mechanical resistance, and abrasive properties.
