Ceramic Point Source is a functional heating element made from pyrolytic boron nitride (PBN). Its key features include high-temperature resistance, excellent stability, and precise localized energy or material release. Some variants also offer electrical insulation, corrosion resistance, or catalytic activity. It is suitable for applications requiring targeted energy delivery, material emission, or precise thermal conduction, offering low contamination and long service life.
Applications:
Material Coating：Used as an evaporation or sputtering source in physical vapor deposition (PVD), releasing metal or compound vapor at precise points to achieve accurate thin-film deposition.
High-Temperature Heating：Serves as a localized heating source in micro high-temperature components, enabling precise point- or area-controlled temperature management in precision instruments.
Catalysis and Sensing：Acts as a point source of activity in micro catalytic reactions or as a detection point for gas temperature sensors, ensuring high stability for catalytic efficiency and sensing accuracy.
Electronics and Semiconductors：Functions as a localized heat-dissipation source for semiconductor chips or as an insulating support point in microcircuits, suitable for high-density electronic packaging and improving device reliability.
