Abstract:
An example of a nanoballoon thermal protection system includes a refractory ceramic foam having carbide balloons. The foam has a closed cell structure not allowing liquid to penetrate through the foam. Each of the carbide balloons is hollow and has a diameter greater than 0 nm and less than 900 nm. Each of the carbide balloons includes a refractory carbide. In addition, a vehicle with thermal shield includes a surface and a first and second nanoballoon closed cell foam coatings. Each of the foam coatings has a melting point temperature greater than 1000 0 C and a density less than 85%. Each of the foam coatings has hollow balloons having a diameter less than 900 nm. Each of the foam coatings includes a closed cell structure not allowing liquid to penetrate through the respective coating. Methods for manufacturing a nanoballoon system and a nanoballoon thermal protection system are also disclosed.
Abstract:
There are provided methods and systems for creating multi-phase covetics. For example, there is provided a process for making a composite material. The process includes forming a multi-phase covetic. The forming includes heating a melt including a metal in a molten state and a carbon source to a first temperature threshold to form metal-carbon bonds. The forming further includes subsequently heating the melt to a second temperature threshold, the second temperature threshold being greater than the first temperature threshold. The second temperature threshold is a temperature at or above which ordered multi-phase covetics form in the melt.

Abstract:
Изобретение и может быть использовано для изготовления углеродсодержащих изделий в огнеупорной и металлургической промышленности, предназначенных, в частности, для футеровки высокотемпературных агрегатов, преимущественно конвертеров, работающих по технологии газокислородной и комбинированной продувки, а также электроплавильных печей и агрегатов внепечной обработки стали, которые работают в непосредственном контакте с жидкими металлами и шлаками. Способ заключается в том, что из смеси, содержащей порошкообразный огнеупорный заполнитель и предварительно вспученный интеркалированный графит, прессуют изделия заданных форм и размеров, при этом огнеупорный заполнитель и предварительно вспученный интеркалированный графит используют при следующем соотношении компонентов, масс. %: огнеупорный заполнитель - 86,0-97,5 вспученный интеркалированный графит - 2,5-14,0.

Abstract:
The invention pertains to antioxidants for refractory materials and processes for producing them. The boron-containing antioxidants for refractory materials are characterised in that they are manufactured by processing used vaporisation boats and/or by-products from the manufacture of such vaporisation boats to form powders.
