Diamond Crystal Model STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-12448
Quick Answer: The Diamond Crystal Model is a ball-and-spoke lattice of the diamond structure. Each black carbon sphere has four holes drilled at the tetrahedral angle of 109.5°, so every atom links to four others in a rigid three-dimensional network.

About This Product
Students begin with one carbon sphere and four connectors to show sp3 hybridisation, then add atoms until the network takes shape. The finished lattice helps explain why diamond is so hard, and why, with no free electrons, it does not conduct electricity. It is used in chemistry, crystallography and mineralogy lessons and pairs naturally with a graphite model for comparing carbon allotropes. The Diamond Crystal Model STEM Lab can be supplied on export terms to Malawi, Japan, Ghana, Côte d'Ivoire, Suriname and Peru.
Frequently Asked Questions
Can the Diamond Crystal Model be taken apart after use?
Yes. The connectors have a firm-grip, easy-release fit so the lattice can be dismantled for storage and built again.
Why is each sphere drilled at 109.5°?
That is the tetrahedral bond angle of carbon in diamond, so the assembled model shows each atom bonded to four neighbours.
