Have you ever wondered what gives luxurious kitchen countertops their lasting beauty, or porcelain tiles their flawless shine? The answer lies in quartz – a mineral also known as quartz stone.
In the world of materials, quartz is not only admired for its beauty but also valued for its durability, hardness, and stability—qualities that few other minerals can match. At Phenikaa Huế, quartz is elevated into a premium material that meets international standards and wins the trust of even the most demanding markets.
1. What is Quartz?
Quartz – also known as silica or quartz stone – is a natural mineral with the chemical formula SiO₂ (silicon dioxide). It belongs to the tectosilicate group, where silicon and oxygen atoms are tightly bonded to form a three-dimensional crystal structure. Quartz accounts for about 12% of the Earth’s crust and is the main component of many rocks, such as granite, sandstone, and sedimentary rocks.
Some outstanding characteristics of quartz:
- Exceptional durability: With a hardness of 7/10 on the Mohs scale, quartz ranks just below minerals like diamond, corundum, and topaz in terms of mechanical strength, making it one of the most durable natural materials. Quartz also has a high melting point (around 1,710°C) and excellent thermal resistance, maintaining its structural integrity even under high temperatures.
- Rich color varieties: Quartz colors originate from mineral impurities or defects in the crystal lattice. For example, amethyst (purple quartz) contains iron impurities; rose quartz is linked to titanium or manganese; smoky quartz results from natural radiation. Rock crystal, the purest form of quartz, is highly valued in optics and jewelry.
- Stability: With a stable crystal structure and strong Si-O bonds, quartz is almost inert to most acids and alkalis (except hydrofluoric acid). This makes it ideal for use in harsh chemical environments or prolonged exposure to moisture.
Thanks to these properties, quartz has become an indispensable raw material in industries ranging from construction and interior design to industrial applications.

2. High-purity Quartz from Phenikaa Huế – characteristics & quality
Phenikaa Huế’s quartz is manufactured from high-purity silica sand with an SiO₂ content of 99.3%, featuring a white color, free from impurities, and sourced from premium domestic mines.
Combined with advanced German production technology (Grenzebach) and strict quality control processes, every grain of quartz guarantees:
- Uniform particle size and stable color
Phenikaa Huế supplies quartz in both granular and powder forms, suitable for a wide range of industries such as engineered stone, porcelain tiles, and coatings.
Uniform particle size ensures stable physical properties of the final product—such as fineness, mechanical strength, and dispersibility in mixtures. This is particularly critical in industries requiring high precision, as uneven particle sizes may lead to defects (e.g., rough surfaces in engineered stone or cracks in porcelain tiles).
The whiteness of Phenikaa Huế’s quartz results from effectively eliminating impurities such as iron oxide (Fe₂O₃), aluminum (Al₂O₃), or titanium (TiO₂), which typically alter the color to yellow, gray, or brown. High whiteness (often >90) is crucial in applications requiring aesthetics or transparency.
- Free from impurities
With a SiO₂ content of 99.3%, Phenikaa Huế’s quartz meets the high-quality threshold for premium classification in the mineral industry. Compared with international standards, this purity level is sufficient for use in engineered quartz stone, porcelain tiles, industrial coatings, and many other applications.
- Certified international standards:
ISO 9001:2015 (Quality Management): Ensures that production processes and quartz products meet international quality standards from mining to processing.
ISO 14001:2015 (Environmental Management): Demonstrates Phenikaa’s commitment to minimizing environmental impact, including dust emissions and wastewater treatment.
ISO 45001:2018 (Occupational Health & Safety Management): Guarantees safe working environments, reducing occupational hazards in mining and mineral processing.
3. Diverse applications of Quartz
Quartz from Phenikaa Huế is trusted across various industries, notably including:
- Engineered quartz stone
Quartz makes up more than 90% of engineered stone, combined with resin and pigments. With a hardness of 7 on the Mohs scale, it delivers outstanding scratch resistance, while its non-porous nature (thanks to its dense crystal structure) provides excellent stain resistance and easy maintenance. This is why engineered quartz stone is highly favored for kitchen countertops, bar tops, and other premium surfaces.
Compared to natural granite or marble, engineered quartz stone offers greater uniformity in color and patterns, making it easier to customize for specific design needs.
- Porcelain tiles & ceramics
Quartz is widely used as a filler or main component in the production of porcelain tiles and ceramics. Its thermal resistance and hardness improve mechanical strength, reduce thermal expansion, and enhance the glossiness of the surface.
Porcelain tiles containing quartz exhibit higher load-bearing capacity, better abrasion resistance, and are ideal for projects requiring durability such as flooring, wall cladding, and public spaces.
- Paints & industrial coatings
Finely ground quartz (silica powder) is widely used as a filler in paints and industrial coatings. Its chemical stability and high hardness enhance abrasion resistance, heat resistance, and surface gloss.
Paint products containing quartz offer superior color durability and excellent resistance to harsh weather conditions, making them ideal for exterior paints, industrial coatings, and anti-corrosion layers in the marine industry. With high-purity quartz from Phenikaa Huế, the requirements of leading paint manufacturers can be fully met.
- Plastics & polymers
Finely ground quartz is also used as a filler in plastics and polymer composites, improving mechanical strength, heat resistance, and reducing production costs. It enhances hardness and dimensional stability of plastics.
In applications such as plastic pipes, electronic casings, or automotive components, quartz contributes to longer lifespan and improved load-bearing performance.
- High-grade glass
Ultra-pure quartz (typically >99.8% SiO₂) is the primary raw material for manufacturing optical glass, reinforced glass, and specialized glass for advanced technologies (such as test tubes and fiber optics). Its transparency and chemical durability ensure consistent product quality.
High-grade quartz-based glass is widely applied in healthcare, telecommunications, and the energy industry. With high-quality quartz sourced from Phenikaa Huế, Vietnam is well-positioned to reduce reliance on imported raw materials for the glass sector.
