Some used for high-temperature work are of refractory metals, usually of platinum, owing to its non-reactive behaviour and low risk of contamination.
22.
An additional complication in studying creep behavior of the refractory metals is interactions with environment, which can significantly influence the creep behavior.
23.
This privately owned company manufactures products based on high-performance materials made from refractory metals such as molybdenum, tungsten, tantalum, niobium, chromium and their alloys.
24.
At LIS, Hall continued his research into refractory metal semiconductors and also designed custom integrated circuits ( ICs ) while developing a line of standard products.
25.
They are forced to land on Pluto, in the hope of finding a deposit of some refractory metal they can use to build a new jet.
26.
Tantalum is a rare and exotic metal belonging to a group known as ` refractory metals .'It was discovered in 1844 by a German scientist Heinrich Rose.
27.
This resistance against deformation at high temperatures makes the refractory metals suitable against strong forces at high temperature, for example in jet engines, or tools used during forging.
28.
Single-cell AMTECs with open voltages as high as 1.55 cm 2 at temperature of 1173 K ( 900 �C ) have been obtained with long-term stable refractory metal electrodes.
29.
*" Partial exceptions include the refractory metals chromium, molybdenum, niobium, tantalum and tungsten, which, while soluble in liquid plutonium and insoluble or only slightly so in solid plutonium ."
30.
Specialized groupings such as the refractory metals and the noble metals, which are subsets ( in this example ) of the transition metals, are also known and occasionally denoted.
