Boron nitride nozzles- a solution to solve technical problems from atomization to 3D printing and molten metals

Image
Powder metallurgy has core process advantages such as high material utilization, low unit energy consumption, and environmental protection. It is a technology that is in line with the future direction of carbon neutrality.   In recent years, with the maturity of powder metallurgy technology and the trend of miniaturization of parts, two emerging process routes, metal injection molding (MIM) and 3D printing (AM), have rapidly emerged.   At the same time, the supply of high-quality powder raw materials has begun to become a major factor restricting the development of the industry.   Small and complex parts are undoubtedly more suitable for injection molding and 3D printing (particle size of 20μm or even smaller), and have been increasingly used in high-end fields such as aerospace, medical, electronics, and military industry.   Therefore, the preparation of metal powders with high purity, good sphericity, small particle size and narrow distribution, and low oxygen cont...

Porous Ceramic as filter

Image
Innovacera have two materials as Porous ceramics one is Aluminum Oxide and the other one is Silicon Carbide. For Aluminum oxide, the common pore size we make is 1um, 15um, 30um, 40um, 50um and 100um. Silicon carbide general pore size is 15um, 30um and 50um, both material porosity is 40%-50% . For other hole size and porosity, it can be customized as well with large quantity.   Between two, Aluminum oxide is more common used than silicon carbide as it is cost effective. But if you need to use under the max working temperature 800 degree-100degree, silicon carbide is only the one that available because Aluminum oxide with max 800 degree.   Here is the material data sheet for both: Alumina Porous ceramic properties: Material composition: Al2O3>=80%, SiO2 16%-18% Density: 2.3g/cm2-2.5g/m3 Hardness: >=50HRA Flexural Strength: >=  40MPa Compressive Strength: >=600 Porosity: 40% Pore Size: 1-2um, 5um, 15um, 30um, 40um, 50um, 100um and customized Max Working temperatu...

Aluminum Nitride (AlN) Ceramic Substrates for Efficient IGBT Module Cooling

Image
  Behind the swift movement of electric vehicles, the operation of photovoltaic power stations, and the precise control of industrial production lines, there is a common core power component – the IGBT (Insulated Gate Bipolar Transistor) module. It converts direct current into alternating current, precisely regulates the motor speed and torque, efficiently controls power switches, and completes the conversion and regulation of electrical energy. It is the “heart” of power electronic devices.   As the industry continuously enhances the performance and efficiency of systems, IGBT modules are evolving towards higher power density, smaller size, and greater reliability to meet the demands of lightweighting in electric vehicles, high power output, efficient operation of new energy inverters, as well as long lifespan and high reliability of industrial frequency conversion equipment. In such applications with high power and high heat load, safely and efficiently discharging the heat ...

Silicon Nitride Ceramic Coil Core

Image
  Silicon nitride coil supports are widely used as sensors in underground mining, geological exploration and other fields. As the coil rack of the sensor coil, the silicon nitride coil rack mainly applies the ultra-high hardness performance of silicon nitride ceramics and the nonmagnetic insulation of  Silicon Nitride (Si3N4) Ceramic . As the sensor coil rack, it must be insulated and nonmagnetic in order to accurately transmit the collected data; At the same time, as a sensor for depth exploration, the underground environment is generally complex, and only the support with high hardness can protect the sensor from damage. In addition, the silicon nitride support has certain protective effects on the sensor coil due to its anti-corrosion, high and low temperature resistance, and low coefficient of thermal expansion. Applications: Induction ceramic coil of induction instrument in practical oil well logging instruments In the field of medical imaging equipment, such as magnetic ...
