The crystal structure of zircon sand is a tetragonal crystal system, and it has a quadrangular pyramid shape. 4.6 ~ 4.71, the change of specific gravity is sometimes related to the composition and alteration state. Zircon cleavage is incomplete. The uniform Mohs hardness is 7-8, the refractive index is 1.93-2.01, and the melting point of 65% zircon is within the range of 2190 ~ 2420 ℃ depending on the impurities contained fluctuation.
