Industrial uses of MinSand
In a wide range of high-performance industrial applications, consistent product quality, temperature stability, and environmental compliance are essential. MinSand, an engineered, synthetic mineral from LKAB Minerals, delivers all three. With its unique physical properties and clean production profile, MinSand has become a valuable mineral in several industrial sectors, particularly foundry applications, ceramics, and refractories.
As industries seek environmentally responsible and durable material solutions, MinSand offers not just a substitute but a step forward. Providing manufacturers with a high-purity, consistent, and environmentally conscious choice.
What is MinSand?
MinSand is a synthetic mineral composed of alumino-silicate and manufactured through a controlled sintering process. The result is a spherical, homogeneous material with a consistent grain shape, high thermal resistance, and excellent flow characteristics.
Unlike natural minerals, MinSand offers predictable performance across batches, giving manufacturers greater control over their end products. It also avoids some of the supply chain, regulatory, and environmental issues associated with traditional alternatives.
Foundry applications
One of the most significant industrial uses of MinSand is in the foundry industry, where it serves as a superior alternative to traditional minerals. In precision casting – especially in automotive and heavy machinery sectors – MinSand provides high-temperature resistance and dimensional stability, which are essential when creating complex metal components.
Its spherical grain shape ensures excellent flowability and compaction, improving mould integrity and reducing the risk of defects such as veining, penetration, or burn-on. These benefits lead to smoother casting surfaces and reduced post-processing costs.
In addition, MinSand is chemically inert and non-reactive, making it suitable for casting both ferrous and non-ferrous metals. Its controlled particle size distribution also helps optimise gas permeability and reduces casting defects, leading to higher yield and lower waste.
Ceramics and refractories
In the ceramics and refractory industries, MinSand is used to manufacture high-performance products exposed to extreme thermal and mechanical stresses. Thanks to its high melting point and thermal shock resistance, MinSand is ideal for creating kiln furniture, insulating bricks, refractory linings, and other heat-intensive components.
In ceramic applications, its consistent grain shape and chemical purity contribute to improved material strength and dimensional stability. This makes MinSand an excellent ingredient in precision ceramic moulds and technical ceramics that require reliable performance under high heat.
For refractory producers, MinSand helps maintain thermal integrity in harsh industrial environments such as steel production, glass manufacturing, and incineration plants. It offers a durable and consistent material base that withstands repeated heating and cooling cycles without degradation.
Environmental and health advantages
Unlike traditional sands, which are often linked to hexavalent chromium (Cr(VI)) contamination and associated health risks, MinSand is free from harmful elements and does not produce hazardous dust. This makes it safer for handling during production, especially in casting environments where air quality and worker safety are a concern.
MinSand’s synthetic nature also enables a more environmentally responsible and traceable supply chain. Manufactured in controlled conditions with minimal impurities, it meets strict environmental regulations and reduces the ecological footprint of industrial operations.
For companies focused on achieving regulatory compliance and improving their ESG (Environmental, Social, and Governance) profile, MinSand provides a proactive solution.
