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 ...

如果您希望可以时常见面，欢迎标星收藏哦~ 来源：内容 编译自 IEEE ，谢谢。 1991年，很少有人能上网。那些在网上论坛发帖或给家里的朋友发电子邮件的人通常通过电话线 上网，信息传输速度最高只有每秒14.4千比特。与此同时，有线电视的普及率正在飙升。到1991 年，60%的美国家庭订阅了有线电视服务；世界其他地区的有线电视铺设速度也在加快。 假设使用日益壮大的有线网络取代电话线接入互联网，通信速度将大幅提升。而将有线电视本身数 字化而非模拟化，将使有线电视提供商能够承载更多频道。实现这一目标的理论——使用模数转换 器和数字信号处理技术将同轴电缆上传输的模拟波形转换为数字形式——已经非常成熟。但实现这 种数字宽带网络所需的有线调制解调器尚未在大众市场上普及。 亨利·萨缪利（Henry Samueli）来了。1985年，他在加州大学洛杉矶分校建立了一个多学科研究 项目，致力于开发数字宽带芯片。在接下来的几年里，他和他的团队开发了各种各样的概念验证芯 片，展示了高性能数字调制解调器的关键构建模块。1991年，萨缪利与他在加州大学洛杉矶分校 的研究生亨利·尼古拉斯（Henry Nicholas）共同创立了博通公司 ...

Core Viewpoint - The article discusses the journey of Henry Samueli, co-founder of Broadcom, highlighting his contributions to digital broadband technology and his philanthropic efforts after achieving significant wealth through the company's success [2][11]. Group 1: Development of Digital Modems - In 1991, the internet was primarily accessed through slow telephone lines, while cable television was rapidly growing, with 60% of U.S. households subscribing to it [1]. - Samueli and his team at UCLA developed key components for high-performance digital modems, leading to the establishment of Broadcom in 1991 to commercialize this technology [2][5]. - The integration of digital and analog signals in modem chips was a significant innovation that set Broadcom apart from competitors [6][7]. Group 2: Early Business Ventures - Broadcom initially secured small defense contracts, which funded their research and development efforts [5]. - In 1993, Broadcom signed a $1 million development contract with Scientific Atlanta, which recognized the potential of Broadcom's modem technology [7]. - The first successful deployment of a digital cable network occurred in 1995, showcasing the effectiveness of Broadcom's technology [7]. Group 3: Market Impact and Growth - By 1995, Broadcom released its first mainstream product, a DOCSIS-compatible modem priced under $20, which contributed to its rapid growth [9]. - The company went public in 1998 with a valuation of $1 billion, which increased to over $60 billion by the mid-2000s, significantly enriching its founders and employees [9]. - Broadcom's success in the digital modem market led to the establishment of industry standards, such as DOCSIS, which facilitated the widespread adoption of broadband technology [8]. Group 4: Challenges and Legal Issues - In the mid-2000s, Broadcom faced an investigation by the SEC regarding stock option practices, which created significant turmoil for the company and its executives [10]. - The legal proceedings concluded favorably for Samueli, who was exonerated of any wrongdoing, highlighting his integrity and contributions to the engineering field [10]. Group 5: Philanthropy and Legacy - Samueli has committed a significant portion of his wealth to philanthropic efforts, particularly in engineering education and health initiatives, through the Samueli Foundation [12][13]. - His foundation has donated over $500 million, focusing on STEM education and community health projects [12][13]. - Samueli's involvement with the Anaheim Ducks hockey team reflects his commitment to community engagement and management [14].
