The invention relates to the field of glass ceramic composite structures and methods for forming composite glass ceramic structures using a low temperature joining process. Glass ceramics, which generally consist of an inorganic, non-porous material having a crystalline phase and a glassy phase, are known for specialized applications. Such glass ceramics are manufactured by selecting suitable raw materials, melting, refining, homogenizing, and then hot forming the material into a glassy blank. After the glassy blank is cooled and annealed, a temperature treatment follows whereby the glassy blank is transformed into a glass ceramic by controlled volume crystallization ceramization.
Glass-ceramics have an amorphous phase and one or more crystalline phases and are produced by a so-called "controlled crystallization" in contrast to a spontaneous crystallization, which is usually not wanted in glass manufacturing. Glass-ceramics have the fabrication advantage of glass, as well as special properties of ceramics. In manufacturing, glass-ceramics are valued for having the strength of ceramic but the hermetic sealing properties of glass. Glass-ceramics are mostly produced in two steps: First, a glass is formed by a glass-manufacturing process.

Following the successful edition in , the Symposium is devoted to academic and industrial partners working on the substitution and recyclability of critical raw materials CRM in electronic, magnetic and energy harvesting devices. Raw materials are the basic, but fundamental, elements for a wealth of current technological applications. New research and development activities are required to improve the fundamental understanding of new material solutions containing reduced or no critical content while maintaining or enhancing the performance of the materials, components and products. The symposium provides an interdisciplinary platform to discuss about CRM alternatives from the modelling, synthesis, characterization, processing and device integration viewpoints. Bringing together researchers from academia and industry we aim at increasing the interaction among scientists, engineers, and students working on different areas of the CRM field that are too often treated separately.

From Wikipedia, the free encyclopedia Jump to navigation Jump to search This article is about the ceramic material. For other uses, see Porcelain disambiguation. Chinese Jingdezhen porcelain moonflask with underglaze blue and red. The toughness, strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved depending on the definition used at some point about 2, to 1, years ago, then slowly spread to other East Asian countries, and finally Europe and the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it has usually been regarded as the most prestigious type of pottery for its delicacy, strength, and its white colour.

Приблизительно это соответствует одной десятитысячной части Галактики, но все, что ты увидишь, характерно и для всего звездного острова. - Ты не увидишь звезд, планет или других физических объектов, хотя их расположение учтено в этой модели. Каждый огонек соответствует звездной системе, породившей вид космоплавателей, способных вывести космический аппарат по крайней мере на орбиту вокруг своей планеты. Огонек светится, пока существует цивилизация космоплавателей.
По-моему, ты можешь подождать до конца обеда, - Николь поглядела на одни из специальных часов, изготовленных для всех землян Ричардом.
Хуже всего восприняла случившееся Элли. Все твердит: она, дескать, просто ужасная мать и никогда не простит себе того, что упустила Никки из виду. а несколько минут назад принялась рассуждать наподобие Макса и Патрика.
Словом, предлагает нам вернуться в Новый Эдем и попробовать наладить отношения с Накамурой. Мол, ради детей она согласна.

Изображение возникло на огромном экране в рубке управления "Ньютона", это было столько лет. Мы все тогда перепугались. - Итак, настал день, - проговорила Синий Доктор цветовыми полосами несколько секунд спустя. - Готова ли ты к переезду в Гранд-отель.
- Наверное, нет, - улыбнулась Николь. - Судя по тому, что говорили вы с Орлом, там у меня не будет уединения. - Твоя семья и друзья с нетерпением ждут тебя, - отозвался Орел.
Теснота угнетала Николь, и она попыталась уйти подальше. Но сделать это было трудно: Николь толкали со всех сторон. Она упустила руку Марии. По толпе пробежала волна, и Николь боком ударилась о стену, ощутив острую боль.
