  • Publication number: 20250299843
    Abstract: Methods, systems, and reactors for chemical vapor infiltration reaction endpoint determination. A system includes a user interface device to enter an inert gas quantity inputted to a reactor, an output device, a hydrogen sensor configured to generate a hydrogen concentration value, a total density sensor configured to generate a total density value, and a processor coupled to the user interface device, the output device, the hydrogen sensor, and the total density sensor. The processor receives the inert gas quantity, the hydrogen concentration value, and the total density value, determines a silicon absorption value based on the received values, generates a signal in response to the silicon absorption value being at or above a predetermined threshold value, and sends the generated signal to the output device. The output device outputs an indication in response to receiving the signal.
