What Exothermics does

Exothermics, Inc. is a privately held advanced materials manufacturer founded in 1996 and headquartered in Amherst, New Hampshire, specializing in cost-effective non-oxide ceramics, refractory metals, and specialty thin film technologies. The firm operates a single, vertically integrated facility that brings together eight interconnected capabilities: Physical Vapor Deposition (DC, bipolar pulsed DC, AC, and RF magnetron sputtering with ion-assisted deposition up to 36-inch diameters), high-temperature metal and graphite hot-zone furnacing, Hot Isostatic Pressing (HIP) can encapsulation capable of >2000°C densification with hard off-gassing and helium leak checking, Ultra High Temperature Ceramic Matrix Composite (CMC) development, full material characterization (SEM with EDS, optical microscopy, UV-to-LWIR optical characterization, BET, particle size, permittivity/permeability, mechanical testing), engineering services (FEA, vacuum chamber design, heat transfer analysis, ply layup), precision CNC and diamond machining, and specialized welding (electron beam and TIG of Group IV and V reactive/refractory metals). Quality systems are certified to AS9100:2016 and ISO 9001:2015.

The company serves a concentrated customer base led by the U.S. Department of Defense, aerospace prime contractors, and sub-tier defense suppliers, with secondary exposure to the semiconductor equipment market and niche industrial applications. Named program participation includes the September 2025 LIFT-led $9 million, four-year Critical Materials Processing consortium with Kratos SRE, Materials Research & Design, and the Air Force Research Lab — a DoD Industrial Base Analysis and Sustainment initiative aimed at domestic ultra-high temperature ceramics, CMC, and carbon fiber development. Revenue mechanics are consultative, project-based, custom quote pricing on multi-year contracts, with sales conducted exclusively through direct enterprise engagement rather than distribution channels. The firm employs 11–50 people and has operated continuously for nearly 30 years as an independently held entity.

Core offering

Exothermics designs, develops, and manufactures custom non-oxide ceramics, refractory metals, and specialty thin film products for aerospace, defense, semiconductor, and industrial customers. Its integrated facility in Amherst, NH provides end-to-end capabilities spanning physical vapor deposition, high temperature furnacing, hot isostatic pressing (HIP), ceramic matrix composite development, material characterization, precision machining, and specialized welding. The company focuses on solving demanding metallurgical challenges for ultra-high temperature and extreme environment applications.

Product overview

Exothermics offers a unified portfolio of advanced materials services centered on cost-effective non-oxide ceramics, refractory metals and specialty thin film technologies for aerospace/defense, semiconductor, and industrial applications. The core offering integrates eight interconnected capabilities: Physical Vapor Deposition (PVD) for thin film coatings; High Temperature Furnacing for thermal processing; HIP Can Encapsulation for hot isostatic pressing; Ultra High Temperature CMC Development for ceramic matrix composites; Material Characterization & Test Facilities for validation; Engineering for design and analysis; Machine Shop for precision machining; and Welding services for refractory metals. These services are designed to work together under one facility, enabling customers to move from materials development through prototyping to production without multiple vendor handoffs.
