High purity alumina crucible 99.8% alumina ceramic crucible

   The raw material of these 99.8% alumina crucible is imported from France. After shaping by cold-isosactic-pressing (CIP) with very high pressure, the green bodies are lathed by CNC machine to get blanks. The blanks are sintered at 1550 degree C and then get the crucibles.    High purity alumina crucibles are commonly used in LED applications due to their excellent thermal conductivity, high melting point, and resistance to chemical attack. LED manufacturing processes often involve high temperatures and corrosive materials, making high purity alumina crucibles an ideal choice.    These crucibles are typically made from high purity alumina ceramic material, which has a purity level of 99.8% or higher. This ensures that the crucible does not introduce impurities or contaminants that could affect the performance of the LED. The thin thickness of the crucible is important for LED applications as it allows for efficient heat transfer and t…
