| In certain cases, small metallic atoms, like boron and beryllium, may enter into restricted interstitial solid solutions. |
| His recovery of the rare and vital ores of tantalum, lithium, and beryllium greatly aided the War Production Board. |
| First, to prove beryllium could diffuse into corundum and create a color change, he heated pink sapphires with beryllium and got yellow rims. |
| The presence of alloying elements such as beryllium, chromium, silicon, and aluminum modifies the nature of the oxide, making it more tenacious. |
| These alloys are very toxic and dangerous if beryllium fumes are not captured and exhausted by proper ventilating equipment. |
| Her history included a relatively short period of exposure to a mixture of silica, hard metal, and beryllium. |
