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...

  • boron nitride nozzle

    Boron Nitride Ceramic Nozzle For Metal Powder Gas Atomization

    BN-2300, one of hexagonal boron nitride based composite, is an ideal materials for an atomizer nozzle, thanks to its high strength, high melting point, high toughness, outstanding thermal shock resistance, excellent machinability and low-friction properties. BN-2300 nozzles for the atomizing process can ensure a continuous flow with no blockage or breakage happening at that level.

  • Ceramic Grinding Media

    Ceramic Grinding Media Balls Beads

    Ceramic grinding balls have been extensively used in high-speed milling applications for blending, grinding, and dispersing. Additionally, ceramic balls and beads are used as abrasive media for ceramic raw materials and glazes in ceramic factories, cement factories, enamel factories, and glass work due to their superior density, stiffness, and wear efficiency.

  • Alumina Ceramics

    Alumina Ceramic Parts

    Alumina parts are made of aluminum oxide, which is one of the most important and versatile materials in the field of oxide ceramics. This material therefore used in a wide range of applications. The alumina ceramic from UNIPRETEC has a Al2O3 purity up to 99.8%. Due to the fine structure of the material and its high surface quality, an unsurpassable combination of properties can be achieved.

  • 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).
