日本石原产业公司开始开发微细薄片状氧化钛制取技术，这种技术是根据日本科技厅无机材质研究所的研究成果，由科学技术振兴事业团委托石原产业开发的，开发期限为三年，开发费用预计为6．5亿日元．目前氧化钛是以硫酸法和淡化法为主生产的，形状几乎为颗粒状，这种氧化钛里聚 Japan’s Ishihara Industries Co., Ltd. started the development of micro-flaky titanium oxide production technology, which is based on the research results of the Japan Institute of Science and Technology inorganic materials research institute commissioned by the Science and Technology Promotion Corps Shi Ishihara industry development period of three years, the development The cost is estimated at 650 million yen. Titanium dioxide is currently based on sulfuric acid and desalination-based production, the shape is almost granular, the titanium oxide poly
