Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content to be translated. | Silicon carbide components, with high-temperature usage, are hard and brittle, and are used after molding. For example, silicon carbide rods and tubes, when used in air-dry conditions, can reach high heat temperatures.1500100-120°C, for use under vacuum conditions; long-term use temperature up to 1350°C under nitrogen atmosphere. |
Silicon Molybdenum Rod | | 2Branch | Silicon molybdenum rods are heated to high temperatures in an oxidizing atmosphere, where a dense quartz glass film forms on the surface, protecting them from further oxidation. Therefore, silicon molybdenum rods possess high-temperature oxidation resistance. In an oxidizing atmosphere, the temperature can reach1800℃, can be used as heating elements for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Tongs for crucibles | | 1Please provide the Chinese content to be translated. | 1. A common chemical instrument, typically used for holding crucibles. Generally made of stainless steel or hard, non-flammable, and difficult-to-oxidize materials. 2. Use clean tongs. 3. When gripping a hot crucible with tongs, preheat the tip of the tongs to prevent the crucible from cracking due to localized cooling. After use, place the tongs with the tip facing up on the table or a asbestos mat. 4. After the experiment, clean the crucible tongs and place them in the laboratory equipment cabinet for drying storage. 5. Use the bent section for holding crucibles, and the pointed end for other uses. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used alone. | |
