Medical Applications to Drive Silicon Nitride Market through 2023
Sintered silicon nitride (SSN) is projected to be the largest segment of the silicon nitride market from 2018-2023.
The silicon nitride market is projected to grow from $90 million in 2018 to $127 million by 2023, according to a report from Markets and Markets, expanding at a CAGR of 7.2% during the forecast period. Silicon nitride (Si3N4) is an inorganic, non-metallic compound of silicon and nitrogen. It offers excellent resistance against abrasion, corrosion, and most chemicals. Among advanced ceramics, silicon nitride has the highest fracture resistance. These desirable properties therefore make silicon nitride a suitable material for use in industries such as solar photovoltaic, automotive, general industrial, aerospace, and medical.
Medical is projected to be the fastest-growing end-use industry during the forecast period. In the medical industry, silicon nitride is used as a material for manufacturing surgical screws, plates, and bearings for use in applications such as prosthetic hips, knee joints, and dental implants. Silicon nitride composites are also used in cervical spacers and spinal fusion devices. It is biocompatible, bioactive, bacterial resistant, and shows excellent bone affinity. In addition, silicon nitride can provide an exceptionally smooth and wear-resistant surface for applications such as bearings for hip and knee replacements in the medical industry.
Sintered silicon nitride (SSN) is projected to be the largest segment of the silicon nitride market during the forecast period. SSN exhibits properties such as high-temperature strength, superior thermal shock resistance, creep resistance, good fracture toughness, oxidation resistance, and excellent wear resistance. SSN is used in applications such as components in glow plugs in diesel engines, pre-combustion chambers, turbochargers, rocker arm pads in spark ignition engines, and components in exhaust gas control valves.
Asia-Pacific is the largest silicon nitride market, and this trend is expected to continue until 2023. In 2017, China accounted for the largest market in the region, followed by Japan, South Korea, and India. China is also projected to grow the fastest, in terms of consumption, between 2018 and 2023.
