Core Viewpoint - The global zircon concentrate market is undergoing structural adjustments, with increased production capacity in major regions like Australia and Mozambique leading to a significant rise in global zircon resource supply. This supply-side effect is transmitted to the domestic market, coinciding with the expansion of China's zirconia industry capacity, resulting in a downward trend in zirconia raw material prices [1][7][9]. Industry Overview - Zirconia, with the chemical formula ZrO₂, is the main oxide of zircon, characterized by its high melting point (approximately 2650℃ to 2715℃), high hardness (Mohs hardness can reach above 7.5), and excellent wear and corrosion resistance [2][4]. - The zirconia industry supply chain includes upstream raw materials like zircon sand, stabilizers, and additives, as well as production equipment. The midstream involves zirconia manufacturing, while downstream applications span structural ceramics, electronic ceramics, dental materials, lithium batteries, and more [5]. Industry Current Status - The global zircon concentrate market is experiencing a structural adjustment, with new production capacities in Australia and Mozambique leading to a significant increase in global zircon resource supply. This supply-side effect is transmitted to the domestic market, coinciding with the expansion of China's zirconia industry capacity, resulting in a downward trend in zirconia raw material prices. As of June 2025, the price of zirconia in China is 46,000 yuan per ton, a year-on-year decrease of 8.00% [1][7][11]. - The Chinese zirconia industry is facing overcapacity, leading to a supply surplus. Companies are compelled to lower prices to compete for market share, affecting the operating rates, which have remained below 50% in recent years. As of June 2025, the operating rate is 34.92%, a decrease of 5.04 percentage points month-on-month and 2.22 percentage points year-on-year [9][11]. Key Enterprises' Performance - The Chinese zirconia industry has developed a stable competitive landscape dominated by a few large enterprises. For instance, Sanxiang New Materials has expanded its electric melting zirconia capacity and has a leading effective capacity of 26,000 tons in China. Dongfang Zircon Industry has a complete integrated industrial chain and is the largest composite zirconia manufacturer in the country [13][17]. Industry Development Trends 1. **Technological Innovation**: The future development of the zirconia industry will be driven by technological innovation, with advancements in production processes like nanotechnology and sol-gel methods enhancing material performance [19]. 2. **Expanding Application Fields**: The demand for zirconia is expected to rise significantly in emerging sectors such as solid-state batteries and biomedical applications due to its excellent properties [20]. 3. **Government Support for Sustainable Development**: The industry will focus on green and high-end development, with government policies promoting sustainable practices and enhancing product quality and competitiveness [21].

Industry Overview - The aluminum hydroxide industry in China is experiencing rapid growth driven by increasing market demand and economic development, with production expected to rise from 2.11 million tons in 2022 to 3.43 million tons by 2024 [1][6] - In March 2025, the Ministry of Industry and Information Technology and other departments issued a plan to limit new alumina production capacity and set a target for recycled aluminum production to reach 15 million tons by 2027 [1][6] - As a result of these policies, companies are shifting focus from "scale expansion" to "quality efficiency," leading to a slight decline in production, with a 0.90% year-on-year decrease in the first half of 2025 [1][6] Industry Chain - The upstream of the aluminum hydroxide industry includes raw materials such as bauxite, caustic soda, and hydrochloric acid, as well as production equipment like pressure leaching systems and fluidized roasting furnaces [4] - The midstream involves the production and manufacturing of aluminum hydroxide, while the downstream applications include flame retardants, pharmaceuticals, electrical cables, insulation materials, coatings, and environmental protection [4] Market Dynamics - The price of alumina reached a nearly ten-year high in 2024 due to resource constraints and environmental regulations, which supported the aluminum hydroxide market [8] - In the fourth quarter of 2024, aluminum hydroxide prices exceeded 3,600 yuan per ton, marking a peak, but by June 2025, prices fell to 1,948 yuan per ton, a 20.33% decrease year-on-year [8] - The industry's gross profit margin fell to -13.24 yuan per ton in late June 2025, a 102.03% year-on-year decline, reflecting the transition pains from scale expansion to quality efficiency [10] Import and Export Trends - In the first half of 2025, China imported 31,900 tons of aluminum hydroxide, a 7.32% increase year-on-year, with an import value of 467 million yuan, up 26.19% [12] - Exports reached 238,600 tons, a 26.69% increase year-on-year, with an export value of 924 million yuan, up 14.86%, driven by higher international prices compared to domestic prices [12] Key Enterprises - China Aluminum Corporation, as a leading player, focuses on high-purity and high-performance ultra-fine aluminum hydroxide, with a revenue of 55.784 billion yuan in Q1 2025, a 13.95% increase year-on-year [16] - Luoyang Zhongchao New Materials Co., Ltd. is recognized for its advanced technology in ultra-fine aluminum hydroxide and has received approval for a project to produce 120,000 tons of high-purity aluminum hydroxide annually [18] - Hebei Wenfeng Industrial Group is facing regulatory risks due to unauthorized production of alumina, with a capacity of 4.8 million tons per year, exceeding market demand [16] Development Trends - The industry is transitioning from a "scale-oriented" to a "technology-oriented" model, with high-end product demand driving growth [20] - Environmental policies and carbon tariffs are pushing companies towards green technologies, with significant energy and carbon emission reductions being achieved by leading firms [21] - The import dependency for high-end aluminum hydroxide products remains high, but domestic companies are accelerating technological breakthroughs to reduce reliance on imports [20][22]
