A review on the susceptor assisted microwave processing

2016/2/15The susceptor assisted microwave joining is a unique application of the susceptor to create the localized heating around the joining surfaces without affecting the other parts. This technique has been shown to be highly efficient to join the poorly microwave absorbing polymers such as thermoplastics (polyethylene, polypropylene etc.).

reactor technology complex: Topics by Science.gov

2018/3/1The mathematical model of the nonstationary heat transfer in a graphite stack of a uranium-graphite reactor in the case of the technological channel dehydration is presented. The results of calculated temperature evolution at the center of the fuel element, the replaceable graphite element, the air gap, and in the surface layer of the block graphite are given.

SiGe and Si Strained

Basically, the minimal common features of these systems were: single wafer susceptor less configuration, lamp heating, cold walls, and low pressure (a few Torr). Rapidly, using relatively simple tools, very impressive material demonstrations were made in the domain of Si SiGe epi: high structural quality epi (proved by excitonic emission) [4,5], functional HBT structures [6], ultra abrupt

Graphite creep negation during flash spark plasma

2020/6/11. Introduction High strength graphite is a material which resists high pressures (∼150 MPa), high temperatures (sublimation occurs at 3650 C) [] allowing it to serve as a tooling for the pressure assisted sintering of various materials including Ultra-High Temperatures Ceramics (UHTC) [2,3].].

Nanomaterials

Oxidized graphite depicts a berthollide layered solid produced by treating graphite with strong oxidants where the graphite surface and edges undergo covalent chemical oxidation []. This technique dates back to 1859 when the chemist Benjamin Brodie performed a similar treatment to elucidate the structure of graphite oxide [ 69 ].

Coatings

During their working lifetime, tools and machinery components are subjected to intensive degradation due to the combination of abrasive wear, corrosion and oxidation. Because of its hardness and high temperature stability, chromium carbide thin films (CrC x) are suitable to increase the performance and extend the lifetime of metallic alloys.

This furnace employs a graphite susceptor crucible packed with carbon black in a vitreous silica sleeve. A water-cooled coil serves as the exciter. The lid is water-cooled and is fitted with a dense carbom sight tube designed to enable temperatures to be taken o g tically without the interference of furnace vapors which fog the atmosphere and any sight window which might be employed.

Flat SiC semiconductor substrate

Wafers were placed onto a graphite susceptor and into the vacuum chamber. The chamber was pumped to vacuum and the susceptor was heated using RF induction heating to temperature above 1500 C. First, a mixture of gases containing hydrogen and hydrogen chloride was fed to the chamber to etch the surface of the wafers.

This article provides an overview of the evolution of the in-situ consolidation (ISC) process over time. This evolution is intimately linked with the advancements in each of the steps of the ISC manufacturing process, is additive in nature, and is limited by the orthotropic nature of composite materials and the physicochemical behavior of the thermoplastic matrix. This review covers four key
