What's the difference between calcium and diopside?
Calcium
Definition:
(n.) An elementary substance; a metal which combined with oxygen forms lime. It is of a pale yellow color, tenacious, and malleable. It is a member of the alkaline earth group of elements. Atomic weight 40. Symbol Ca.

Diopside
Definition:
(n.) A crystallized variety of pyroxene, of a clear, grayish green color; mussite.
Example Sentences:
(1) From above mentioned study results, we can say that diopside is mechanically strong, and because of new bone created along the block surface at an early stage, it is stabilized in the bone soon after the implantation and is the most suitable as a material of dental implant in all the blocks used in this study case.
