Silicon nitride light source suits FTIR spectrometry
Kyocera has developed a silicon nitride (SN) light source for Fourier-transform infrared (FTIR) spectrometers using its SN heater and glow plug portfolio. The company’s SN heaters are robust and fast ramping, serving as glow plugs for diesel engines and igniters for furnaces. Applied to spectrometry, Kyocera’s SN technology delivers high spectral emissivity to enable more accurate material identification.
The heater structure embeds a printed heating element in silicon nitride ceramic. Each heater pattern can be customized to meet application requirements, including such parameters as wattage, output temperature, and heating area.
The durability of the SN material results in lower failure rates and an extended duty cycle compared to conventional light source solutions. Its fracture toughness is more than twice that of silicon carbide, providing enhanced resistance to cracking and chipping during handling and installation. According to Kyocera, its SN heaters maintain consistent performance across more than 150,000 cycles without significant degradation.
