For manufacturers of engineered quartz slabs, titanium dioxide (TiO₂) is one of the most significant raw material expenses. With monthly consumption ranging from 20 to 50 tons and a target addition ratio of just 2% to 8%, even a small reduction in TiO₂ usage can translate into substantial annual savings.

Subtitanium Powder T166 offers a practical, high-performance alternative.

The Technical Advantage

T166 Subtitanium Powder is engineered with a particle morphology and particle size distribution closely matching that of rutile TiO₂. It delivers the following key benefits:

High Whiteness (≥93) – T166 exhibits a blue-white phase, providing excellent opacity and brightness in quartz slab formulations.

Replacement Ratio of 15-25% – In most applications, T166 can replace 15-25% of the TiO₂ in the formulation without compromising whiteness or coverage. For some applications (using T188), the replacement ratio can exceed 50%.

Excellent Compatibility – The powder disperses uniformly with rutile and anatase TiO₂, ensuring consistent color development across batches.

Cost Savings – With its lower unit cost, replacing a portion of TiO₂ with T166 can reduce overall raw material costs by 15-30%, depending on the specific formulation.

Why This Matters for Quartz Slab Production

Recommendation for Clients

Given the client’s consumption of 20-50 tons per month and an addition ratio of 2-8%, we recommend starting with a 15% replacement test. T166 is the preferred choice for its high whiteness and fine particle size. T188 (nano-grade) is recommended for applications requiring a higher replacement ratio or a pure white phase.

By adopting Subtitanium Powder T166, quartz slab manufacturers can achieve their target whiteness and coverage while enjoying significant material cost reduction—a true win-win in today’s competitive market.
