2025年1—4月，太阳能发电新增装机量达到104.93GW，4月单月新增装机45.22GW，基本为上半年 光伏装机史上月度最高水平。随着"430"、"531"抢装结束，光伏产业链上硅片、电池片、组件各环节价 格经历涨跌波动后目前均有持稳倾向，而多晶硅环节则在本已现金流亏损的状态下，于4月中旬再次进 入价格下行通道，行业困局再度深化，目前企业仍在积极采取应对措施。 从企业生产经营策略来看，部分企业选择了检修，部分企业开始产能置换。首先，在5月份内，多 晶硅生产企业数量由之前的13家减少至11家，对目前已经稳定低负荷生产的企业来说，再度调低生产负 荷一方面会带来产品稳定性等问题，另一方面则会一定程度上增加生产成本，因此这部分企业倾向于暂 停生产进行检修，且后续部分企业也将有新增停产检修计划。另外，目前头部企业正在积极进行产能置 换，用运行较为良好的小产线，替换已经生产一定时间的大产线，并对全年的预期产量进行了近10万吨 的显著下调。整体来看，多晶硅企业开工率的积极调整有利于当前供需矛盾的缓解以及未来市场预期的 稳定。 从行业库存数量来看，截至2025年4月底，我国多晶硅库存约为39万吨，如果按照目前下游消费情 ...

Core Viewpoint - The article explores the fascinating history and production process of glass, highlighting its transformation from a rare luxury item to an essential part of everyday life [2][6]. Production Process - Glass is primarily made from sand, which consists mainly of silicon dioxide (SiO2). When combined with soda (sodium carbonate, Na2CO3), the melting temperature of silicon dioxide is lowered, allowing it to become a molten glass known as water glass (sodium silicate, Na2SiO3) [4]. - To achieve clear glass, iron must be absent from the raw materials; otherwise, the glass will take on a green hue. Various metal oxides can be added to create colored glass, such as cobalt oxide for blue, copper oxide for red, chromium oxide for green, and ferric oxide for brown [4]. Historical Context - Historically, glass was a luxury item reserved for royalty and nobility, but it has since become a common household item, used in mirrors, light bulbs, and various containers [6]. Applications - Ordinary glass, composed of Na₂SiO₃, CaSiO₃, and SiO₂, serves multiple functions, including providing shelter from the elements while allowing sunlight to enter. Techniques such as acid etching can create intricate designs on glass [9]. - Tempered glass, which is rapidly cooled after heating, is known for its safety features, breaking into small, blunt pieces rather than sharp shards [9]. - Quartz glass, made solely from silicon dioxide, is utilized in high-temperature and high-purity applications, such as in the production of high-performance glass fibers and semiconductor manufacturing [12].
