Product Information
- Terbium is a soft and ductile silver gray rare earth metal, this terbium cube is made of 99.95% purity terbium plate.
- Each terbium cube with a dimension 1inch*1inch*1inch /25.4mm, double face laser engraved informations,the cubes are just perfect for collections.
- The terbium cube is vacuum packed, do not touch rare earth metals directly with your hands, otherwise they will go black,please take them out with gloves and place them in the matched acrylic box,erbium is a rare earth element, and rare earth elements are all active,although terbium is relatively stable in air, it still darkens, oxidizes, and has small spots over time,vacuum packaging also darkens because the packaging bag still has a small amount of oxygen and water vapor,therefore, the best way is to soak it in liquid paraffin,although it cannot achieve absolute deoxygenation, the effect is the best.
- Terbium is one of the elements with magnetism at room temperature, but its magnetism can only be clearly observed with strong magnetism, it’s mainly used as research on magnetic materials, terbium cubes can be used in labs, offices, science rooms, teachers, gifts, science demonstrations, suitable for different ages, good understanding of metals, elements, different densities, can be placed in the classroom to stimulate students' interest in chemistry.
- Compared with 0.39 inch terbium cube, 1 inch terbium cube is bigger, heavier, and more textured,but 0.39 inch terbium cube is more suitable for collection and put on your periodic table display rack.
