Examples of "silicate" in Sentences
- If the child coughs it is given _bans-lochan_, which is said to be some kind of silicate found in bamboos.
- The principal ore mineral is uranophane, a hydrated calcium-uranium silicate, which is believed to be an oxidation product of pitchblende.
- That kind of planet would have to develop differently from Earth, Mars and Venus, so-called silicate planets made up mostly of silicon-oxygen compounds.
- By theory, [20] 50 grams of quartz will require 88.5 grams of the carbonate, or 140 grams of the bicarbonate, to form sodium silicate, which is a glassy, easily-fusible substance, making a good slag.
- Silica forms with lime a compound, calcium silicate, which is not very fusible; but when alumina and other oxides are present, as in clays and in most rocky substances, the addition of lime gives a very fusible slag.
- “Clay” as a mineral refers to a “cousin” of micas; that is, a silicate mineral containing structural sheets of silica tetrahedra tetrahedral arrangements of one Si and 4 Oxygen atoms, with the Oxygen atoms at the 4 corners.
- If the bicarbonate is used, and heat is applied gradually, steam and carbonic acid are given off at a comparatively low temperature, and the carbonate is left; at a higher temperature (about 800° C., or a cherry-red heat) the carbonate fuses attacking the quartz, and giving off more carbonic acid; as the heat increases, and the attack on the quartz (which of itself is infusible) becomes complete, the whole mass settles down to a liquid sodium silicate, which is sufficiently fluid to allow the gold and lead to settle to the bottom.
