1)26. We first performed a melting experiment of MgO at ambient pressure to check the validity of the temperature measurement in our optic system. A clear temperature plateau was found at 3,010±140 K in the power versus temperature profile (Fig. 1b), which agrees well with the ...
详细解释: 以下为句子列表: 英文: Included in ceramics are porcelain such as pottery; abrasives such as emery used on sand-paper, refractories such as tantalum carbide, with a melting temperature of about 3870 centigrade, and structural clay such as brick. ...
Tantalum carbide (TaC) is an ultrahigh-temperature ceramic binary compound with the highest melting temperature (3770C) of its analogues. Combined with high chemical stability, good thermal conductivity, high hardness, etc., it is identified as an excellent refractory material with wide applications ...
Melting of tantalum at high pressure determined by angle dispersive x-ray diffraction in a double-sided laser-heated diamond-anvil cellsurface structure, morphology, roughness, and topographygoldatomic force microscopyThe high pressure and high temperature phase diagram of Ta has been studied in a ...
Since little data exists on the optical properties of tantalum and hafnium carbides, especially at extremely high temperatures, in the current work first approximation true temperature versus time curves (thermograms) were obtained starting from NSE values at 650 nm reported by Deadmore19 up to ...
a Determination of the Melting Point of Tungsten and Tantalum. Not Available WE Forsythe 被引量: 0发表: 1911年 Thermal conductivity of aluminum, copper, iron, and tungsten for temperatures from 1 K to the melting point B. Lankford, "Thermal conductivity of Aluminium, Copper, Iron, and ...
Formation of intermetallic compound layer at the fiber/matrix interface has also been reported by some workers. This interdiffusional effects and aggressive fiber/matrix reactions degrades the mechanical properties of the fiber. In the present work, effect of tantalum as alloying element and barrier ...
Melting points of Hydrocarbons, Alcohols and Acids Melting temperature (°C and °F) with carbon number up to C33. Metal Alloys - Melting Points Alloys and their melting points. Metal Alloys - Specific Heats Specific heat of metal alloys like brass, bronze and more. ...
英文: The amorphous surface layer of tantalum was obtained by anodic oxidation in melting nitrate after plasma-nitriding at relative low temperature, and the composition, phase structure and property of coating were tested.中文: 摘要采用低温离子渗氮后再熔盐阳极化的方法,在钽表面形成厚度达微米数量级的...
These low melting temperatures have not been reproduced by other experiments or by the- oretical estimates, and are likely to underestimate the high pressure melting temperature of bridgmanite. Other than these, the highest pressure static experiments only reach about 60 GPa. The higher pressure ...
