Crucible

Crucible is used in the laboratory to contain chemical compounds when heated to extremely high temperatures.Crucibles are available in several sizes and typically come with a correspondingly-sized lid.When heated over a flame, the crucible is often held inside a pipeclay triangle which itself is held on top of a tripod.

Hydrogen storage in carbon materials—A review

Graphite is sp2 hybridized with a sheet like structure wherein all atoms are weakly bonded and exist in a plane, and is held together by van der Waal's forces to the sheets above and below. Graphite naturally found in earth with around 20 wt% impurities.

Methods adopted for improving the collection

At temperature above 2,000 C, graphite crucible becomes very soft. Tantalum is found more suitable for evaporations requiring higher temperature. Tantalum crucibles of various internal volumes (3–6 mm diameter and 7–12 mm height) are frequently used in electron beam evaporation of rare earth isotopes.

Silicon carbide

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..

Only from the late 18th century do we find explicit allusions to the artificial mixture of clay and graphite during paste preparation for crucible manufacture. In these sources, the term used for the temper is Wasserbley ('liquid lead', or 'lead water'—Beckmann 1780, as cited in Stephan 1995, 31; Beckmann 1787, as cited in 1976, 15).

Mould Fluxes in the Steel Continuous Casting Process

2012/2/22This simple test has been used by some laboratories to estimate viscosities of molten fluxes. A mass of 10 g of powder is placed in a graphite crucible and then is melted at a specific temperature (T). The melted flux is maintained at that temperature for 15 min

Was graphite first discovered at the Borrowdale mine? –

"Graphite was first discovered in the 1560s in the Lake District of England" – Pencils You Should Know by Caroline Weaver. This statement about the discovery of graphite is often repeated, to the point that it seems to be a known historical fact. Let's take a look. In Pencil People, Thomas Smith notes that Borrowdale was previously the home of Furness Abbey, and that there are records

The graphite crucible (with the sample) was weighed before and after the experiments to determine the char yield. Each experiment was performed at least 5 times. As a result of the limited sample amounts, selective analyses and characterization were carried out for selected (not all) char samples subsequently.

Charge transport properties of cryolite silica melts

in a Thermo Scientific Blue M crucible furnace and was heated to the target temperature at the rate of 8 C/min. The crucible was covered by a graphite lid to maintain a reducing environment inside the crucible and also reduce the evaporation of fluoride

Physical Vapor Transport (PVT)

Abstract: The present research was focused on the effect of porous graphite plate in TaC-coated crucible on crystal quality and resistivity of semi-insulating SiC crystals. Two SiC crystals grown with/without porous graphite plate in TaC-coated crucible were systematically compared. 6H-SiC polytype was obtained on both crystals regardless of porous graphite plate.

CFD analysis and experimental measurements of the liquid

2021/2/18For each experimental case Table 4 resumes the graphite crucible emptying times and the mean particle velocities with respect the nozzle diameter and the injection pressure of the aluminum jet. As can be seen from the table below the emptying time is inversely proportional, as expected, with respect of the two variables cited before.

Investigation of Na2CO3–CaO–NaCl (or Na3AlF6) additives

2021/3/1(4) The small residual peaks at about 35.6, 60, and 71.8 correspond to SiC formation (SiC, 1810 K) due to the chemical reaction between SiO 2 and the graphite crucible wall at smelting temperatures of T ≥ 1810 K, as given by Eq. (Yang et al., 2019b).
