CSC Financial research note says Chinese dental zirconia makers have received notices from Japan's Tosoh suspending supply of zirconia powder, signaling raw-material shortages have moved from expectation to reality after overseas rare-earth constraints. YSZ (yttria-stabilized zirconia), a yttria-doped high-performance ceramic, faces steep domestic-foreign price divergence: domestic yttrium oxide quoted about 55,000 yuan/ton, Rotterdam port price $457.50/kg and Baichuan reports a European price of $1,175/kg, with some spreads exceeding 100x. Baichuan data show similar widening for other oxides: dysprosium ~8x, terbium ~5x, gadolinium ~40x, scandium ~6x. Rare earths are essential additives for high-end materials and manufacturing; tightening overseas supply and expanding spreads imply Chinese producers of rare-earth-added high-end materials could gain global market share, supporting upstream, midstream and downstream segments of the domestic rare-earth industry chain.
