Chinese SiC Companies Achieve Technology Breakthroughs, Accelerating Import Substitution of High‑End Products

Over the past five years, China’s silicon carbide industry has undergone a profound transformation from extensive expansion to high‑quality development. Domestic enterprises represented by ShunCheng New Materials have achieved significant breakthroughs in core technologies such as micro powder preparation, fine classification, impurity purification, and surface modification. Today, the quality of some domestic high‑end SiC micro powders has reached or approached the advanced levels of traditional powers like Japan and Germany, with notable improvements in particle size distribution concentration (D85/D50 ≤1.5), batch stability (CpK ≥1.33), and magnetic foreign matter control (≤100 ppb).

Historically, the high‑end SiC micro powder market was long monopolized by Japanese (e.g., Yakushima, Fujimi) and German (ESK) companies, leaving domestic high‑end abrasives, precision ceramics, and semiconductor polishing heavily dependent on imports. This situation is now being overturned as local technical capabilities improve. According to data from the China Machine Tool & Tool Builders’ Association, China’s import volume of high‑end SiC micro powder decreased by about 12% year‑on‑year in 2024, while the market share of domestic brands exceeded 35% for the first time. ShunCheng’s high‑purity micro powder has successfully entered the supply chains of several listed companies that previously used imported materials, covering precision grinding, carbon‑ceramic brakes, and high‑end coatings.

Import substitution not only reduces raw material costs for downstream domestic industries (average reduction of 15‑25%) but also shortens supply chains (from 3‑6 months to 2‑4 weeks), enhancing supply chain security and resilience. ShunCheng will continue to invest in independent R&D, focusing on industrial production technologies for submicron‑level ultra‑fine powders (D50 ≤0.5μm) and high‑purity SiC (≥99.9%), striving for a stronger position in the future high‑end market. The company also looks forward to technical cooperation with international customers to jointly upgrade SiC material standards.
