UNIPRETEC offers a full range of solutions for supporting parts during sintering in reducing or oxidizing atmospheres up to 1700ºC. UNIPRETEC has the industry's broadest range of manufacturing methods – including vacuum forming, casting, pressing and CNC machining – that allow us to customize setters to best suit customer requirements in prototype or production volumes. Mullite, alumina and alumina-zirconia compositions are available for applications in sintering of technical ceramic, electronic[...] Szczegóły...  Hot Pressed Boron Nitride
Hot Pressed Boron Nitride products are manufactured as powders, finished components and blanks, as well as liquid coatings for various high temperature applications in molten metal equipment. Boron Nitride is an advanced ceramic material available in powder, solid, liquid and aerosol spray forms and in solid state it can be machine very easily using diamond tooling.
Hot Pressed Boron Nitride can easily be machined to close tolerances in virtually with any complex shape.[...] Szczegóły...  A wide variety of purity grades from 60% up to 99.7% pure of Aluminium oxide are available on the market. Typical grades that are used for modern industrial applications are of high purity from 95% to 99.7% Amongst the various advanced ceramics that exist today, alumina is the most commonly used ceramic materials that has a wide range of properties and a very competitive cost due to high tech of manufacturing techniques.
Properties of Aluminium Oxide
- Good mechanical strength under compressive[...] Szczegóły...  Unlike other ceramic materials, zirconium oxide (ZrO2 - also known as zirconia) is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.
Zirconia is characterized through its tribological performance (friction and wear) in moving applications and furthermore:
- Excellent fracture toughness
- Very good wear resistance
- High corrosion stability
-[...] Szczegóły...  Ceramic Materials Frequently Used:
- Alumina (92%, 95%, 96%, 99%, 99.5%, 99.7% Al2O3)
- Silicon Nitride (Gas Pressure Sintered Si3N4)
- Boron Carbide (Hot Pressed B4C)
- Zirconia (Partially Yttria Stabilized ZrO2)
- Macor (Machinable Glass Ceramic)
- Boron Nitride (Hexagonal Hot Pressed BN)
Some of the highly desirable properties of ceramics are:
- High Strength
- High Fracture Toughness
- High Hardness
- Excellent Wear Resistance
- Good Frictional Behaviour
- Anti-Static
- Non-Magnetic
-[...] Szczegóły...  This type of glass frosting powder is mainly used in the glass further processing fields which include the further manufacture of the wine bottles, grape wine bottles, and the other glasswares.
The technology procedure: Mix a proportion of glass frosting powder and sulfuric acid together, churn up the mixture fully, then submerge the await etching glassware into it for 1--3 minutes, take it out, clean and dry it.
The etched effect: The surface of the etched product feels smooth and delicate,[...] Szczegóły...
