Spherical Silicon Carbide Industry

The global spherical silicon carbide market size was estimated at USD 3.68 billion in 2023 and is projected to grow at a CAGR of 11.0% from 2024 to 2030.

Silicon carbide’s exceptional properties, such as high thermal conductivity, high breakdown voltage, and superior efficiency at high temperatures, make it ideal for the electronics industry. The material is particularly suited for developing high-power devices like electric vehicle (EV) inverters, energy-efficient chips, and semiconductors. As industries push toward next-generation electronics, SiC is used in high-frequency and high-temperature applications. This supports the demand for more efficient electronic components in electric vehicles (EVs), renewable energy systems, and data centers.

Silicon carbide (SiC) plays a crucial role in the renewable energy industry, particularly in solar inverters and wind turbines, where it significantly improves energy efficiency. Its ability to reduce power loss and increase energy conversion efficiency in photovoltaic systems and power grids has driven demand. As countries aim to meet stringent energy goals and reduce carbon footprints, using SiC in renewable energy technologies is expected to expand significantly.

The global shift toward EVs is another critical driver for SiC demand. In EV powertrains, silicon carbide offers higher efficiency than traditional silicon-based devices, leading to longer driving ranges and faster charging capabilities. With major automakers scaling up EV production, the demand for SiC-based semiconductors is expected to rise. In addition, SiC is used in automotive components such as braking systems and engine parts, further boosting its adoption.

Moreover, the aerospace industry is turning to silicon carbide for high-temperature, wear-resistant applications such as jet turbine blades and aerospace electronics. SiC’s ability to withstand extreme environments while maintaining its strength makes it a preferred material for producing critical components that must endure high pressures and temperatures. Furthermore, SiC is used in advanced defense systems for sensors and radars, where durability and performance are paramount.

The growing demand for specialty ceramics, especially in defense, aerospace, and electronics sectors, contributes to the rising need for silicon carbide. Its hardness and resistance to wear and corrosion make it ideal for producing durable ceramic components. Industries that require materials with high mechanical strength, such as the automotive and steel sectors, are also turning to SiC-based ceramics to enhance performance and reduce maintenance costs.

Product Insights

Based on product, the below 30.0 μm particle size segment commands the highest demand due to its suitability for high precision and performance applications. The 30.0 μm particle size range is critical in electronics, particularly power electronics, semiconductors, and thermal interface materials (TIMs). Silicon carbide in this size range produces efficient, high-performance components like SiC-based power transistors, diodes, and other semiconductors. Fine SiC particles improve electrical conductivity and allow higher switching frequencies, which is essential for developing compact and efficient electronic devices like electric vehicle (EV) chargers and photovoltaic inverters.

Fine particles below 30.0 μm are widely used in applications that require effective heat dissipation, particularly in power-intensive industries. In TIMs used for high-power devices like processors, batteries, and energy systems, finer SiC particles help improve thermal conductivity, making the heat transfer process more efficient. This characteristic is essential in consumer electronics and industrial machinery, where overheating can cause significant performance loss.

While the below 30.0 μm segment has the highest demand, the 30.0-50.0 μm particle size range is expected to be the fastest-growing due to several factors. This segment balances performance and cost, which appeals to a wide range of industrial applications.
