INNOVACERA | technical ceramic solutions

  In the field of   High-power Power Electronics, the ceramic wafers make a great contribution,   when you think of high-tech materials, your mind probably jumps to silicon, graphene, or whatever Elon Musk is tweeting about this week. But here at Innovacera, we’d like to introduce you to a true backstage superstar— Aluminum Nitride , or AlN if you’re in the know.   Now, AlN might not have the celebrity status of silicon, but it’s got something better: thermal conductivity up to 230 W/m·K. That’s 9.5 times that of alumina, in case you were wondering. It’s the kind of performance that makes engineers blush and thermal management experts weep with joy.     Whether it’s chilling with LEDs, keeping laser diodes in line, or holding its nerve in high-temperature sensors, AlN does it all—and with style. It’s electrically insulating, mechanically strong (450 MPa, if you’re keeping score), and resistant to thermal shock, molten metal. Innovacera offers AlN wafers fro...

Nowadays, the industries of advanced manufacturing, new energy materials and fine chemicals are developing rapidly. People have increasingly strict requirements for the particle size accuracy and purity of powder materials. Powder grinding is a crucial process in the material preparation procedure. The grinding efficiency and process stability are largely dependent on the performance of the grinding media itself. In many high-demand industrial fields, grinding balls made of ceramic materials have emerged due to their excellent performance.   1.Ceramic Grinding Balls Ceramic grinding balls (or grinding media) are commonly used in grinding equipment such as ball mills, stirred mills, and vibratory mills. During grinding, the balls impact and frictionize the materials to refine and disperse particles, achieving smaller size and more uniform distribution. Compared to traditional metal grinding balls, ceramic materials have higher hardness, greater wear resistance and stronger chemical ...

  Porous ceramic chuck table  is a so important part in semiconductor equipment such as silicon wafer processing. Porous Ceramic Vacuum Chucks  are widely used as important components of equipment in silicon wafer, semiconductor compound wafer, piezoelectric ceramic, glass, LED, semiconductor package component substrate, optical component thinning, cutting and so on. The advantages include the following: Strong permeability: Uniform air permeability and water permeability to ensure the uniform stress and firm adsorption of the silicon wafer, so that it does not slip during the grinding process. Compact and uniform structure: Due to the dense and uniform  microporous ceramic , the chuck table is not easy to adsorb silicon powder abrasives and is easy to clean. High strength: No deformation during grinding, to ensure that the silicon wafer is uniformly stressed at all points during grinding, and is not easy to edge breakage and debris. Long service life: The surface sh...
