专有名词解释
- 薄膜沉积:有机物蒸发皿在薄膜沉积技术(如热蒸发或有机蒸气沉积)中起着至关重要的作用。通过加热蒸发皿并使材料蒸发,即可在基板上沉积一层薄膜。
- 样品制备:有机物蒸发皿用于干燥和浓缩有机化合物的溶液或悬浮液,使溶剂蒸发,留下所需的固体残留物。
- 溶剂蒸发:有机物蒸发皿用于通过温和加热从溶液或混合物中去除溶剂。
- 结晶:蒸发皿用于结晶过程。通过缓慢蒸发溶剂,可以在蒸发皿中形成结晶固体。
- 浓缩和体积减小:蒸发皿用于浓缩溶液或减小液体样品的体积。
- 前驱体合成:有机物蒸发皿用于合成各种有机和无机材料。它们可用于蒸发和加热前驱体溶液以获得所需的化合物或材料。
优点
- 耐热性:可承受高温而不会变形或熔化。
- 耐化学性:惰性,能抵抗大多数有机溶剂,防止相互作用或污染。
- 多功能性:可与各种有机溶剂兼容。
- 多种尺寸和形状:提供不同的尺寸和形状以满足实验需求。
- 样品浓缩:通过去除溶剂促进样品浓缩。
- 易于观察:浅设计可以直观地观察蒸发过程。
- 经济高效:与其他实验室设备相比,价格相对便宜。
注意事项
- 加热后的坩埚不能骤冷,应使用坩埚夹取出。
- 在三角架上加热坩埚。
- 使用前,将坩埚逐渐加热至 500 摄氏度,使用后存放在干燥处。
- 选择适量的原材料填充坩埚,避免过满,以防止热膨胀引起的裂纹。
- 尽可能使用勺子而不是游标卡尺取出熔融金属。如果使用游标卡尺,请确保其符合坩埚的形状,并施加最小的局部力,以避免缩短坩埚的寿命。
- 避免将强氧化火焰直接喷射到坩埚上,这会氧化坩埚材料并缩短其使用寿命。
