高纯石英石英电子布行业专家交流 20250821 摘要 AI 处理器需求推动石英电子布市场，预计 2027 年市场规模达 30-50 亿 元，单价约 200 元/平方米，但价格受供需影响。 石英电子布价值链包括高纯石英砂（利润率 30%-40%）、石英棒（利 润率 25%-30%）和石英纤维。国内纤维技术与信越、东坊等国外企业 存在差距。 军工级石英纤维利润远高于消费级，前者一吨可达百万元级别，后者毛 利率约 20%-30%，单价 20-30 万元/吨。 石英纤维和石英布是高纯石英价值链中壁垒较高的环节，原料稳定性至 关重要，国内纤维直径水平与国外先进水平仍有差距。 太平洋公司占据高端高纯石英市场 70%-80%份额，产品稳定性好，价 值高，总产能约 1 万吨至 1.2 万吨，受益于半导体和光伏领域稳定增长。 中国发现新的高纯石英矿种——高铖石英矿，或将打破依赖印度、非洲 和巴西矿源的局面，但美国斯福斯派恩矿在品质一致性上仍具优势。 半导体级高纯石英市场稳定增长，预计增长 10%-15%，合成石英与天 然石英占比各半，国内企业正积极进行合成石英国产替代，但经营数据 仍有提升空间。 Q&A 石英电子布市场的总量 ...

石英纤维在高频高速产品应用前景明确，但产业链各环节如基材生产、 CCL 验证、电子布生产等仍在验证磨合阶段，影响量产进度。 国内石英纤维厂商中，泰波和菲利华进展较快，但供样结果和整体性能 表现仍有提升空间；宏和是唯一参与验证的国内电子布厂，产品质量有 所改进。 国外方面，日本阿萨伊公司采购中国原丝织布，供样最多但良率需提升； 日东纺积极寻求中国石英纱线，以支持其织布验证和后续量产。 中材在淀粉型浸润剂技术上具有优势，电子级石英纤维技术领先于菲利 华，后者产品主要应用于航空航天和兵器领域，尚未进入电子通讯市场。 洪河公司曾从多家公司采购石英纤维进行试量产和市场验证，预计其石 英布年产量可达数万米，目前正积极进行客户认证，但尚未有 CCL 厂商 完全通过验证。 石英纤维纱线价格约为 2000 元/公斤，织成布后每平方米售价约为 300 元。单丝直径 5 微米的石英纤维样品价格更高，约为 3,500-4,000 元/ 公斤。 电子级石英纤维主要供给国内电子织布厂，如红河、林州光远等，红河 进展最快，已向韩国斗山、松下和台光电子供样验证。预计 2026 年电 子级石英纤维供应量将达到 200 吨，60%出口海外。 Q ...
