石英砂：高纯度需求引领，半导体与光伏市场成消费主力 头豹词条报告系列

Investment Rating - The report does not provide a specific investment rating for the quartz sand industry. Core Insights - The quartz sand industry is experiencing a significant increase in demand for high-purity quartz sand, particularly driven by the semiconductor and photovoltaic markets, which are becoming the main consumption sectors. The supply of refined and high-purity quartz sand is relatively tight, leading to a supply-demand imbalance. The industry is also moving towards more environmentally friendly and sustainable practices due to rising environmental standards and the push for sustainable development [6][7][8]. Industry Definition - Quartz sand is a natural sand composed of quartz mineral particles, primarily made of silicon dioxide (SiO2). It is widely used in various industrial applications due to its high refractoriness, chemical stability, and good thermal conductivity. The industry can be categorized based on purity levels: ordinary quartz sand (SiO2 content 90-99%), refined quartz sand (SiO2 content >99%), and high-purity quartz sand (SiO2 content >99.9%) [4][5]. Industry Characteristics - The quartz sand industry is characterized by a yearly increase in production, with a supply-demand balance remaining tight. The demand for high-purity quartz sand is continuously growing, especially in high-tech sectors such as electronics and renewable energy. Environmental sustainability is becoming a key trend in the industry's development [6][8]. Industry Development History - The quartz sand industry in China has evolved through several stages, from exploration and purity discovery in the early years to significant breakthroughs in production technology and capacity expansion in recent years. The industry has transitioned from reliance on imports to self-innovation, showcasing strong development potential and competitiveness [9][12]. Industry Scale - The market size of the quartz sand industry in China grew from 22.24 billion RMB in 2018 to 39.68 billion RMB in 2023, with a compound annual growth rate (CAGR) of 12.28%. It is projected to reach 61.01 billion RMB by 2028, with a CAGR of 9.19% [26][27]. Supply Chain Analysis - The quartz sand industry supply chain consists of upstream raw material supply, midstream production, and downstream application. The industry heavily relies on overseas quartz sources, with over 90% of procurement coming from abroad, primarily from India. This reliance poses challenges to supply chain stability [18][21]. Downstream Applications - Quartz sand is widely used across various industrial sectors, particularly in the semiconductor and photovoltaic industries. In the semiconductor sector, high-purity quartz sand accounts for 65.30% of consumption, while the photovoltaic industry is rapidly increasing its demand for high-purity quartz sand due to the growth of solar energy installations [24][30]. Competitive Landscape - The quartz sand industry is highly competitive, with significant technological barriers and high industry concentration. Major players include Unimin, TQC, and Quartz Corporation, which dominate the high-purity quartz sand market. Unimin holds a 90% market share in high-end quartz sand products, leveraging its unique resources and technological advantages [39][41].
