How does zero or ultra-low crystalline silica engineered stone compare with traditional quartz slabs?

PropertyZero / Ultra-Low SilicaTraditional Quartz Slabs

Crystalline Silica Content (XRD) < 1% ~85%
Mohs Hardness 6.3 ± 0.5 6.5 ± 0.3
Water Absorption 0.02% 0.05%
Flexural Strength 40 ± 3 MPa 35 ± 2 MPa

Analysis:
Crystalline Silica Content: The silica content is drastically lower (< 1%), reducing occupational and environmental health risks compared to traditional quartz (~85%).
Hardness: Comparable to quartz, ensuring durability and resistance to everyday wear.
Water Absorption: Lower absorption means superior stain resistance and easier cleaning.
Flexural Strength: Higher strength helps prevent cracking during handling and installation.
