Gas atomization is a kind of high efficient technique to produce high-quality metal powders. It makes the metal powders with spherical shape, clean surfaces and uniform particle sizes. And gas atomization is becoming more and more popular in modern powder production due to its high quality production.     In order to support the processing of gas atomization, INNOVACERA presents a series of atomizing nozzles including Boron Nitride and Zirconia material. We have BMA, BSC, BMZ, BAN and BSN which are all well used for metal powder’s atomization, especially BMA and BMZ are very popular. Hot pressed Boron Nitride nozzles are often used for producing nickel powder, copper powder and aluminum powder. The max working temperature is 1700- 1800℃ in vacuum. BN atomizing nozzles The benefits of BN atomizing nozzles 1.Non wetting make it reduce the frequency of nozzle replacement 2.Good surface finish ma...

  The laser tubes usually used in CO2 laser machines are categorized into DC glass、RF metal tubes and ceramic tubes. But Metal-sealed lasers are the most proven technology on the market for high-performance CO2 lasers. Metal laser tubes are sealed metal chambers made of metal and ceramic. Metal is typically stainless steel or other durable alloys and ceramics are usually alumina; they are brazed to form a feedthrough of up to 1.0 x 10 -10 atm-cc/sec. The tube is filled with a specific mixture of gases in the ratio of 1:1:8, typically: Carbon Dioxide (CO2): Nitrogen (N2): Helium (He). The metal and ceramic laser tubes use a technique called “radio frequency” to stimulate the gases to produce the beam. Using RF has advantages over DC voltage, including lower energy consumption, better control of the engraving process, and longer life, resulting in a higher-quality laser beam output over a longer period of time. Metal and ceramic laser sources can be air-cooled or water-cooled, depend...

  Innovacera has been a supplier in the field of high-temperature boron nitride ceramics for more than 13 years. Now, with the expansion of our production area and the renewal of our hot press furnace, we have taken another step forward and expanded the production of new boron nitride solids .     The basis for all products is hexagonal boron nitride (hBN), also known as white graphite. Its properties are comparable to those of graphite: flake structure, softness and high temperature stability in an inert gas atmosphere. hBN is oxidatively stable up to 900 ° C in air, while graphite starts to oxidize at around 350 ° C. In addition, hBN is electrically insulating and white, which is a decisive advantage in certain applications. Due to the wide range of properties that depend on its composition, this product family is divided into two product lines: the Pure line and the Composite line.     Due to the wide range of properties that depend on its composition, this p...

  Innovacera introduces high-quality ceramic laser waveguides ! Kindly note that we use state-of-the-art grinding equipment to create highly accurate grooves and complex internal structures for CO2 waveguides. At the same time, maintaining precise dimensional tolerances is critical to ensure that the apertures can properly guide the photon beam and ensure a tight seal with the gas medium. Our custom waveguides provide superior performance, reliability, and exceptional durability and efficiency, ideal for a wide range of laser applications.   CO2 lasers were one of the first gas lasers developed and remain one of the most powerful and efficient lasers to date, with an output power to pump power ratio of up to 20%. CO2 lasers produce beams in the infrared and microwave bands (wavelengths of 9.4 to 10.6  µ m), and lasers with high enough power can melt or ablate a wide range of materials they are focused on.     Carbon dioxide (CO2) lasers typically use a pump cavi...

  In the Zirconia ceramic family, there is a material that can endure the high temperature of 2200 degrees centigrade. We call it Magnesium Stabilized Zirconia ceramic. It is a refractory material. Although 95% of the composition is zirconium oxide, its performance is quite different from the white zirconia ceramic(Y2O3 partially stabilized zirconia ceramic).     From its appearance, it is yellow in color and with porosity. We have two kinds of magnesium-stabilized zirconia ceramic. One with low porosity its a density is ≤52g/cm3, one with high porosity its a density a little higher, 5.4-5.6g/m3. But their main composition is almost the same. They can be used in air, vacuum, or protective atmosphere environments. Following is the detail of the material data sheet.   Property Item Units MSZ-L MSZ-H Composition ZrO2 % ≥95 ≥95 Al2O3 % ≤0.2 ≤0.2 SiO2 % ≤0.4 ≤0.4 MgO % ≤2.9 ≤2.9 Fe2O3 % ≤0.1 ≤0.1 TiO2 % ≤0.1 ≤0.1 Physical Color Yellow Yellow Density g/cm3 ≤5.2 ≤5.4-5.6 Po...

  Silicon nitride (Si3N4) ceramic   igniters have significant advantages over ceramic heaters, mainly reflected in their high temperature resistance, rapid heating ability and thermal stability, making them very popular in many high-temperature application scenarios. Today, we will mainly introduce the characteristics, common application scenarios, advantages and precautions of silicon nitride igniters.      1. Core characteristics  1) High temperature tolerance  2) Silicon nitride ceramic igniters can heat up to 1000-1400 ° C in a very short time (2-10 seconds), and can work stably in a high-temperature environment of 1200-1400 ° C for a long time. This feature makes it suitable for scenarios that require rapid start-up and maintenance of high-temperature uniform distribution, such as industrial kilns, burners, mold heating, etc.  3) Thermal surface stability  4) The heating element is encapsulated in a dense silicon nitride ceramic matrix ...

INNOVACERA is glad to offer new standard filament assemblies, a critical component in mass spectrometry applications for the analytical and medical industries.   Principle of the mass spectrometer filament The mass spectrometer filament is also called the ion source filament or the cathode filament. It is mainly made of high melting point metals such as  tungsten (W)  alloy or molybdenum alloy. Its function is similar to that of ordinary filaments. It mainly produces electron emission under high pressure and excites gaseous molecules into ions, thereby generating the charge-to-mass ratio signal required for mass spectrometry.     These filament supports are manufactured using 96% alumina, selected for its good electrical insulation and high temperature stability. Customers can choose between two and four-pin options, with the pins brazed into the alumina insulator ready for filament welding. Our brazing process makes the filament considerably more resistant...
