  What Is The PBN Performance Advantages And Usage 18 Dec, 2023 at 10:03 am Pyrolytic boron nitride (PBN)  belongs to the hexagonal crystal system, and its purity can reach 99.999%. It is acid and alkali resistant, anti-oxidation, has good thermal conductivity, is dense, and can be processed. Due to the CVD process, pyrolytic boron nitride has a near-perfect layered structure, resulting in anisotropic thermal conductivity, making it an ideal material for making crystal growth crucibles. It is made of chemical vapor deposition (CVD) of ammonia and boron halides under high temperature and high vacuum conditions. It can not only prepare PBN sheets, but also directly prepare PBN final products such as crucibles, boats, and coatings. Pyrolytic boron nitride is different from ordinary hot-pressed boron nitride (HBN). It does not need to go through the traditional hot-pressing sintering process and does not add any sintering agent. Therefore,the obtained product has the following sig...

  High purity Sapphire viewports   offer a hermetically-sealed lens with upgraded optical, mechanical, and corrosion properties across a wide spectrum. Innovacera’ Sapphire viewports are rated for both high vacuum(HV) and ultrahigh vacuum(UHV) applications. The use of high purity sapphire and low expansion alloys allow these viewports to be repeatedly baked out at temperatures up to 350°C. The crystal orientation of our sapphire viewports is normal to the optical axis, also referred to as a 90° orientation. All viewports up to one-inch in diameter are made with UV grade sapphire. Specifications: – Materials Flange 304 Stainless Steel Glass Substrate Sapphire Seal Vacuum Brazed Features: Single-crystal Sapphire Positioning/direction: 0-90° Ultraviolet and regular grades Optically polished substrate faces UHV compatible construction High Temperature rated to 350°C Stainless steel / NiFe construction Custom Solutions By Customer Request Sapphire Properties： Property Value Chemica...
