Ultrafine minerals which interisted in the field of planetary science have been produced by the advanced gas evaporation method (AGEM). By the use of reaction between ultrafine particles and thin film, enstatite and spinel phases were produced. It turns out that these phases can be produced about the half of the production temperature of the enstatite and spinel in generall method. The present method opens a new field to produce the compounds by the use of reactivity of the ultrafine particles.A new method to controll amorphous cabon grain size, fullerene and microcrystallite size of carbon grain have been found. The opitical properties on these particles have been measured and discussed from the view point of carbon star formation.By the measurements of IR spectra on alumina film and particles produced various method, it turns out that eta-phase alumina was formed on oxidation of Al. The phase transition process to alpha-alumina by the heating was elucidated.

利用先进的气体蒸发法（AGEM）生产出了对行星科学领域有兴趣的超细矿物。利用超细颗粒与薄膜反应，制备出顽辉石相和尖晶石相。结果表明，这些相的生成温度仅为辉化辉石和尖晶石的一半左右。本方法为利用超细颗粒的反应性制备化合物开辟了新的领域。发现了一种控制非晶碳晶粒尺寸、富勒烯尺寸和碳晶粒微晶尺寸的新方法。从碳星形成的角度对这些粒子的光学性质进行了测量和讨论。通过对氧化铝膜和各种方法制备的氧化铝颗粒的红外光谱测量，证实了铝在氧化过程中形成了α相氧化铝，并阐明了加热向α相氧化铝转变的过程。
