An irritant; Prolonged inhalation may cause pulmonary fibrosis known as silicosis. [MSDSonline] Silicosis is caused by inhalation of dust containing particles of crystalline silica in the respirable size range. Some non-crystalline forms of silica are relatively nontoxic. [APHA, p. 446] See Zirconium.

Contains small amounts of uranium and thorium; Causes moderate skin and eye irritation by abrasive action; [IUCLID] Contains 0.1-2% aluminum oxide and aluminum silicate and trace amounts of crystalline silica, titanium dioxide, uranium, and thorium; Abrasive action may cause skin and eye irritation; Non-toxic by ingestion; [Continental Mineral Processing MSDS] See Zirconium silicate.
