Refractory > ASTM C133 - Orton Ceramic

The cold strength of a refractory material is an indiion of its suitability for use in refractory construction. (It is not a measure of performance at elevated temperatures.) These test methods are for determining the room temperature flexural strength in 3-point bending (cold modulus of rupture) or compressive strength (cold crushing strength), or both, for all refractory products.

Refractory Metal - an overview | ScienceDirect Topics

Refractory metals, molybdenum, tungsten, niobium, tantalum, and rhenium have a nuer of characteristics in common.They are all BCC metals, and as shown in Figure 1(a), have some of the highest melting points among the elements.Tables 1–4 also show that they have very high densities; of the first four metals niobium has the lowest at 8.57 g cm −3 and tungsten the highest at 19.25 g cm −3.

2020/7/30· Also in the refractory material returned by the Stardust mission moderately elevated D/H ratios have been observed (McKeegan et al. 2006). The absence of hydrated minerals, however, led Bockelée-Morvan et al. ( 2015 ) to the conclusion that the measured D/H ratios in the Stardust samples are not representative of the D/H ratio in the ices of 81P/Wild 2.

ABSTRACT. We review the complex relationship between the dust-to-gas mass ratio usually estimated in the material lost by comets, and the refractory-to-ice mass An alternative scenario is that the chunks are ejected as dehydrated sheets of area, e.g. >1 m 2 each and thickness <2 mm, and then reshaped into chunks by the gas drag in the coma (Blum et al. 2017).
