MARKET CHALLENGES

Long Validation Cycles and Qualification Risks Constrain Supplier Switching in Automotive and Semiconductor End Uses

Si₃N₄ producers face a structural challenge from lengthy qualification and validation cycles in automotive and semiconductor end uses, which slow supplier onboarding and increase switching risks. End customers in these sectors require extensive material testing, reliability assessments, and long-term performance validation before approving new suppliers, particularly for components used in safety-critical or high-power applications. As a result, changing suppliers can take multiple years and carries a high risk of supply disruption if the transition is not carefully managed. This limits producers’ ability to quickly win new business or replace lost volumes and reduces short-term flexibility in responding to shifts in demand.

• According to automotive electronics standards such as AEC-Q and ISO 26262, components used in automotive-grade power and control systems must undergo extensive qualification and reliability testing under extreme temperature, vibration, moisture, and lifetime conditions, which significantly extends validation timelines and makes supplier changes slow and high-risk.
