The Great Dome on Mercury Beryl is a silicate of aluminum and beryllium. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public It is the machine that is not of iron and beryllium and crystal, but of pure, living force. The Last Evolution Wayne felt his heart starting to pound; D-N beryllium was big. The Judas Valley For instance, beryllium ions in the body can be deadly; beryllium poisoning is nasty stuff. Cum Grano Salis "Random samplings from various parts of the area show that the ash consists of magnesium, lithium, and beryllium carbonates." Anything You Can Do ... That is, it is a compound in which oxide of silicon is united with the oxides of aluminum and of beryllium. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public He was letting down a spliced beryllium plumb line, his gaze riveted on the slowly turning horizontal drum of a windlass which contained more than two hundred feet of gleaming metal cordage. The Sky Trap The prospect of enough D-N beryllium to make fusion power really cheap could cause a panic if we didn't handle it properly. The Judas Valley When you think of it, sir, probably the first metal they ever used was aluminum—where our ancestors used copper—and they had a beryllium age next, instead of iron. The Aliens But far, far away other things detonated, and what had been proud structures of steel and beryllium, armed and manned, became mere incandescent vapor. Talents, Incorporated Thus it is really to be regarded as a compound of the two oxides, aluminum oxide and beryllium oxide. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public Sorry—but I didn't build the IP fleet, and there are lots of tungsten and beryllium on Earth. The Ultimate Weapon Then we picked up the double-nucleus beryllium deposit on our detectors. The Judas Valley And right now, sir it’s probably as expensive for them to refine iron as it is for us to handle titanium and beryllium and osmium—which are duck soup for them!

Occult Chemistry Clairvoyant Observations on the Chemical Elements To him also is due the isolation of the elements yttrium, beryllium, and titanium, the observation that silicium can be obtained in crystals, and that some meteoric stones contain organic matter. Scientific American Supplement, No. 362, December 9, 1882 We left the ship at about five in the morning, and spent most of the day climbing up to the spot where we had detected the beryllium. The Judas Valley His job would be the actual climbing of the mountain where the double-nucleus beryllium was located. The Judas Valley They ran a check on the double-nucleus beryllium toward the end of the week, after it had been fairly safely established that no apparent harm was going to come to them. The Judas Valley Thus 1,568 atoms have been packed into the beryllium type, and our wonder is again aroused by the ingenuity with which a type is preserved while it is adapted to new conditions. Occult Chemistry Clairvoyant Observations on the Chemical Elements They were going to look for Captain Wayne with it, just as they had searched out the double-nucleus beryllium. The Judas Valley Actually, it could be found eventually with the D-N beryllium as a guide. The Judas Valley The third member of this group repeats the a groups of beryllium and the b groups of calcium, and they dissociate into the bodies already described under these respectively. Occult Chemistry Clairvoyant Observations on the Chemical Elements It is as simple in relation to its congeners as is beryllium to its group-members.
