Several conditions for hydroxyapatite ceramic preparation were used: sintering at 1150 °C in air or under H 2 O vapor flow, quenched in water at room temperature after sintering, or slow cooling inside the furnace. Depending on specific combinations of these preparation conditions, in the resulting ceramics significant differences are observed

1C240.b. refers to porous metal formed by compacting and sintering the materials in 1C240.a. to form a metal material with fine pores interconnected throughout the structure. 1C350 Chemicals, which may be used as precursors for toxic chemical agents, as follows, and "chemical mixtures" containing one or more thereof:
20091027A plasma catalyst consistent with this invention can include one or more different materials and may be either passive or active. A plasma catalyst can be used, among other things, to ignite, modulate, and/or sustain a plasma at a gas pressure that is less than, equal to, or greater than atmospheric pressure.
2018918Between 30 and 35 pct of the cleaned CO-rich off-gas is typically utilized as an on-site energy source for, e.g., heating ladles, raw material drying, preheating the furnace charge, and chromite pellet sintering/prereduction. Unused cleaned off-gas is typically flared on top of purpose-designed stacks.
The sintering process plays an important role in the BaTiO 3 properties and many works have reported the influence of the conventional sintering process and the microwave sintering on the materials properties. As it is well-known, microwaves interact readily with polar species producing heat and this is the case of dielectric materials such as
HIGH-TEMPERATURE processing of materials by microwave (MW) radiation has emerged as a novel technique and shown promise for sintering, brazing, melting, heat treatment, and synthesis of a wide variety of materials including powder metals.[1-4] To date, MW sintering is an established process for ceramics and has been realized in industrial
The experimental results show that the electrical resistivity of film deposited at 200 °C is 8.12 × 10 −4 Ω cm, and can be further decreased to 4.74 × 10 −4 Ω cm with post-deposition annealing at 400 °C for 2 h under 3 × 10 −3 Pa. In the meantime, its band gap energy can be increased to 3.90 eV from 3.83 eV.
preparation of the specification (tender and performance specification) conception of the equipment, e.g. a crystal growing furnace layout and design of the equipment (mechanics, electrics, automation) choice of sub-contractors for parts, components and sub-systems assembly of the components and sub-systems assembly of the equipment preparation
Since the microwave energy increases the kinetic energy of atoms, molecules or ions inside the sintered material, the sintering activation energy of the material is reduced, which is advantageous in reducing the sintering temperature and shortening the sintering time. At the same time, microwave heating has the characteristics of rapid heating
The empirical observations of microwave enhancements have been broadly known as microwave effect. Even though no satisfactory theory existed to explain the effect but the presence the electromagnetic waves (EMW) during microwave heating is clearly the key. In this paper, microwave effect on grain growth of alumina ceramic is presented.
• C/C-SiC hybrid composite has been fabricated through densification by PIP process of porous C/C composite with polycarbosilane. This hybrid composite combines the advantages of C/C composite and SiC. • C/C-SiBOC composite has been fabricated though densification by PIP process of porous C/C composite with borosiloxane oligomers.
