СПОСОБ ПОЛУЧЕНИЯ СПЛАВА С ДИСПЕРСНЫМИ ОКСИДАМИ

Номер: RU2333269C2

Изобретение относится к порошковой металлургии, в частности к получению дисперсно-упрочненного оксидами сплава. Может применяться в качестве конструкционного материала для устройства по производству стекла. Получают порошок или присадочный пруток сплава, состоящего из металла матрицы и одного или двух, или более металлов-присадок. Проводят окисление металла-присадки в порошке сплава водой с образованием дисперсных частиц путем введения порошка сплава или присадочного прутка сплава в высокоэнергетическую шаровую мельницу с водой и перемешивания в воздухе или кислородной атмосфере. После окисления проводят формование с уплотнением порошка сплава или присадочного прутка сплава. Способ позволяет получить материал с равномерно распределенными мелкодисперсными упрочняющими частицами и высокой прочностью. 23 з.п. ф-лы, 5 ил.

НОВЫЕ СУСПЕНЗИИ ОСНОВАННЫХ НА ЗОЛОТЕ И ПЛАТИНЕ БИМЕТАЛЛИЧЕСКИХ НАНОКРИСТАЛЛОВ, ЭЛЕКТРОХИМИЧЕСКИЕ СПОСОБЫ ИХ ПРОИЗВОДСТВА И ИХ ПРИМЕНЕНИЯ

Номер: RU2617055C2

Изобретение относится к фармацевтически приемлемым суспензиям для лечения рака. Суспензии включают воду, усилитель обработки и золото-платиновые биметаллические нанокристаллы, которые имеют средний размер частиц менее чем 50 нм, присутствуют в суспензии в общей атомной концентрации металла, равной 2-1000 ч/млн, и имеют поверхности, обладающие по меньшей мере одной характеристикой, выбранной из: (1) нет органических химических составляющих, прилипших или прикрепленных к упомянутым поверхностям, и (2) являются по существу чистыми и не имеют химических составляющих, прилипших или прикрепленных к поверхностям, отличных от воды, продуктов лизиса воды или усилителя обработки, ни один из которых не изменяет функционирование нанокристаллов. Также суспензии характеризуются тем, что имеют рН между 5 и 12 и дзета-потенциал по меньшей мере -30 мВ. Кроме того, изобретение относится к способам получения суспензий и способам лечения пациента с раковым состоянием, включающим введение данных суспензий.

Between 0.005 and 10 wt.% calcium (Ca) may be included, and more than 50wt.% of rutile has been shown to be integrated. Rutile may therefore be used to reduce melt loss due to calcium from an aluminum or aluminum alloy melt.

A sputtering target for a magnetic recording film which contains carbon, the sputtering target is characterized in that the ratio (I G /I D ) of peak intensities of the G-band to the D-band in Raman scattering spectrometry is 5.0 or less. The sputtering target for a magnetic recording film, which contains carbon powders dispersed therein, makes it possible to produce a magnetic thin film having a granular structure without using an expensive apparatus for co-sputtering; and in particular, the target is an Fe—Pt-based sputtering target. Carbon is a material which is difficult to sinter and has a problem that carbon particles are apt to form agglomerates. There is hence a problem that carbon masses are readily detached during sputtering to generate a large number of particles on the film after sputtering. The high-density sputtering target can solve these problems.
