  Boron nitride   is an excellent self-lubricating ceramic that can withstand high temperatures and maintain its lubrication capabilities in high vacuum environments. Usually composed of hexagonal boron nitride (P-BN), it has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipation material and high temperature insulation material. Due to its high thermal and chemical stability,  boron nitride crucibles  are used in high temperature applications. They are also used in metal casting because it bonds well to metals, as a sandwich of metal borides or nitrides is formed. The benefits of using a boron nitride crucible are its low wettability to molten metal, relatively high resistance to thermal shock, and conductivity with low thermal expansion. Another advantage of boron nitride crucibles is their very high operating temperatures and appropriate inert gas protection (temperatures above 3000°C h...

  About Hot-Pressed Aluminum Nitride (AlN) Hot pressed aluminum nitride ceramics  are sintered by vacuum hot pressing. The aluminum nitride purity is up to 99.5%(without any sintering additives), and density after hot pressing reaches 3.3g/cm3, it also has excellent thermal conductivity and high electrical insulation. The thermal conductivity can be from 90 W/(m·k) to 210 W/(m·k). The aluminum nitride ceramic mechanical strength and hardness of the product after high temperature and high pressure are better than those of the tape casting process, dry pressing and cold isostatic press method. Hot pressed aluminum nitride ceramics have high temperature resistance and corrosion resistance, and will not be eroded by various molten metals and molten hydrochloric acid. Typical Application of Aluminum Nitride (AlN) Cooling cover and magnetic resonance imaging equipment As the substrate of high-frequency surface acoustic wave device, large-size and high-power heat dissipation in...

Direct Plated Copper (DPC) is a newest development in the field of Ceramic Substrate PCBs, its process is by magnetron sputtering technology to deposit a metal layer (Ti/Cu target) on the surface of the ceramic substrate which result in copper thickness’ ranging from 10um to 130um, and then photolithography to form circuit patterns. electroplating is used to fill in the gaps and thicken the metal circuit layer, and the solderability and oxidation resistance of the substrate is improved through surface treatment, finally remove the dry film and etch the seed layer to complete the substrate. Direct Plated Copper Substrate Key attributes : – Superior CTE and excellent thermal conductivity – High reliability and durability – Good Mechanically performance – Low electrical resistance conductor traces – Superior high-frequency characteristics – Fine line resolution – Low temperature process (below 300℃) guarantee the quality of ceramic and the metallized layer, also reduce the cost. Direct Pl...

There are a lot of practical uses for   ceramic   in LEDs. First of all, they’re possibly the best material to use for heat sinks. This is because aluminum replaced copper as the cheaper alternative for heat sinks in LEDs. However, although it is relatively malleable and effective in conducting heat, it’s not that environmentally friendly to dispose of. This is where ceramic comes in! Ceramic is a very cost-productive material to use for heat sinks. This is because it is very easily available, can be printed out into heat sink shapes very easily and only needs the LED chip to be stuck directly onto it. This means using ceramic material for your LED’s heat sinks removes the need for PCB boards and thermal adhesives. Ceramic is a great alternative to previously used aluminum as they’re more environmentally friendly and contribute better to the overall heat dissipation of the light. There are below benefits to use  ceramic heat sinks : Longer Lifespan:  Having highly ef...

We are pleased to introduce here our new product Filament Assembly supports, which is a drop-in replacement filament for ion trap mass spectrometers. Direct replacement for products offered by Thermo, Varian, Perkin-Elmer, Teledyne and Hitachi. Customers can choose from two-pin and four-pin options, tensioned and aligned to maximize mass spectrometer performance. These filament assembly are manufactured from our alumina ceramic, chosen for its good electrical insulation and high temperature stability. Innovacera’s brazing process makes the filament more resistant to temperatures of around 700°C, compared to standard adhesives that typically can only withstand temperatures up to 350°C. Welding method Ceramic to Metal Brazing (or Soldering) Glass to Metal Sealing If you are interested, please contact us. Our experienced team of engineers will select the appropriate brazing fixture, joint design and process for your application.

Alumina ceramic  is widely applied in the high-temperature industry because of its excellent resistance to high temperatures. It can withstand high temperatures up to 1800℃, in addition to its stable chemical properties, high mechanical strength, and electrical insulation. So  Alumina ceramic tube  is commonly used in high-temperature furnaces, thermocouples tubes, insulating tubes, and corona electrode’s square ceramic tubes. In this articles, we would like to discuss how to use alumina ceramic tubes at high temperatures to ensure optimal performance and longevity. 1. Proper handling and storage Alumina tubes are brittle, avoid any sudden impacts or shakes to prevent breakage. During storage, it should be stored in a dry and clean environment to prevent contamination. 2. Preheating When using alumina tubes, we should be preheated gradually, the heating rate should be controlled at 5 degrees per minute until it reaches the desired temperature, the slower the better. 3. Cl...

  With the development of intelligent devices in the direction of digitalization, miniaturization, low energy consumption, multifunctionalization, high reliability, etc., the closely related electronic packaging technology has also entered a period of ultra -high -speed development. Commonly used electronic packaging substrate materials include three categories: organic packaging substrate, metal base composite substrate, and ceramic packaging substrate. With the evolution of intelligent devices, traditional substrate materials can no longer meet the current needs of the current development. Therefore, the base board materials are evolved from organic materials, metal materials, and evolution to  ceramic materials . As we all know, ceramic materials have many advantages compared to traditional substrate materials: 1. Low communication loss – The dielectric constant of the ceramic material itself makes the signal loss smaller. 2. High thermal conductivity – the heat on the chip...
