Devolatilization and calcination of distillate bottoms: For devolatilization, 1 to 5 g of each distillate bottoms sample was placed in a high-temperature crucible and then the crucible placed in a static muffle furnace. The oven with crucibles was purged of air with nitrogen before placing lids on crucibles.
This wafer fusion furnace is a custom built unit designed for the fusion of different material types (such InP and Si) to create new heterostructures for novel electronic and optoelectronic devices. Custom made bonding fixtures are loaded into the furnace through a purged glove-box that is oxygen free to below 10 ppm with a dew point near -80°C.
Sample Size: 200x200x 200mm (8"x8"x8") BOGIE HEARTH FURNACE: RT3 series high-temperature bogie-hearth furnace is an exclusive patents and together with the most advanced high-temperature. International bogie electric furnace technology, it has become the major product exported to the international market and joining in international competition
Loss‐on‐ignition was calculated after samples had been placed in a furnace at 850 °C for 30 min . Total nitrogen (Kjeldahl) concentrations were measured by colorimetry after digestion with concentrated sulphuric acid. Extractable phosphorus concentrations were determined by method two of Bray & Kurtz (1945). Samples were prepared using
furnace provides excellent absolute detection limits because the amount of sample is small, and the volume of atomic vapor produced is also small. The atmosphere of the graphite furnace is free of fuel and oxidant gases reducing chemical interferences such as the formation of refractive oxides.
A new stabilization concept for coke water slurries based on the capillary suspension phenomenon (Koos and Willenbacher, 2011) is presented. Adding a small amt. of an immiscible, secondary fluid to the slurry results in the formation of a sample-spanning particle network controlled by capillary forces.
- (a) No new pressure vessel or plant shall be taken into use in a factory after coming in force of this rule unless it has been hydrostatically tested by a competent person at a pressure, at least 1.3 times the design pressure and not pressure vessels or plant which has been previously used or has remained isolated or idle for a period
1980812What is claimed is: 1. In a dental resin composite comprising a resin and a filler material the improvement which comprises the replacement of at least a portion, if not all, of said filler material with a non-toxic, substantially uniform internally microporous glassy filler having a median refractive index between about 1.51 and about 1.64 and a density between about 2.37 and about 3.15 grams
In case of sample no. 3 the reappearence of anorthite, microcline and muscovite meant a firing temperature below 1000oC. This value was changed to 850-900oC by the presence of illite, kaolinite (meta-kaolinite) and carbonates because at this level it started their decomposition. The diopside in samples no. 4, 5 and 6 indicated a firing temperature
Article 35 of the EURATOM Treaty requires that each Member State shall establish facilities necessary to carry out continuous monitoring of the levels of radioactivity in air, water and soil and to ensure compliance with the basic safety standards (1). Article 35 also gives the European Commission
2013111The unexposed regions are washed away by a developer solution. After etching or other processing, the remaining photoresist is removed by oxygen plasma ashing or stripping. • Modification of electrical properties consists of doping transistor sources and drains in diffusion furnaces and by ion implantation.

The CTF single zone and TZF 3-zone wire wound tube furnaces use a wire element that is wound directly onto a fixed diameter integral ceramic work tube. This simple and economical design of both the CTF and TZF provides a tube furnace that can be used without the need to purchase an additional work tube.
