Quartz (SiO₂)

Quartz is the second most abundant of all minerals, is hard, crystalline, and composed of SiO₂. It is a free-flowing granular solid. It is hard, wear-resisting, and stable. As a filtration media, it can effectively remove suspended solids, organic matter, and colloidal particles. Quartz crystals can exhibit a piezoelectric effect and produce an electric voltage along certain directions of the crystal under pressure.

Purities are available between 99% and 99.99%

Typical Applications

Quartz is used in the manufacture of glass & labware, ceramics, silica brick, cement, and mortar. It also has important applications in the electronics industry due to its piezoelectric effect. Quartz Sand is used as a filtration media.
Ground quartz is abrasive in stonecutting, sandblasting, and glass grinding. Powdered quartz is used in making porcelain, scouring soaps, sandpaper, and wood fillers. Recent uses are with solar panels.

Sustainable Qualities

Quartz is considered sustainable because it is a naturally occurring mineral with a low environmental impact compared to synthetic materials. It is abundant and widely available, reducing the need for resource-intensive extraction processes. Additionally, Quartz is highly durable and resistant to wear and tear, making it a long-lasting material that requires minimal maintenance and replacement. Its natural beauty and versatility make it a popular material for sustainable design and construction projects. As a naturally occurring, long-lasting, and versatile material, Quartz can contribute to a circular economy by promoting sustainable resource use and reducing waste.

View Open Cell Metal Foam
Open Cell Metal Foam
Open cell metal foam, also known as reticulated foam, features 100% open cells with a homogenous structure. The open cells provide a path through the foam in any direction, allowing gas and liquids to pass at control flow rates and buffer pressure. Open foams have high surface area-to-volume ratios which offer large heat transfer rates. They are lightweight, with high compressive strength, stiffness, energy absorption, and low specific weight. Specific properties and applications vary based on foam material. The most popular open-cell metal foam products are Aluminum and RVC foam.

Aluminum metal foam is a fully customizable rigid, opened pore three-dimensional network of interconnected solid aluminum ligaments. The aluminum foam has a high strength-to-weight ratio, strong compression strength, and a high surface area per unit volume.
View Hemp Fiber
Hemp Fiber
Hemp Fiber (Bast Fiber) is a high-yield commercial fiber crop that grows from seed. Hemp stalks are harvested for their fibers and grow on the outside of the plant’s stalk, similar to the bark of a tree. Hemp fibers are advantageous as they are flexible, have low density and abrasiveness, and have mechanical properties comparable to glass fiber. There is also quantitative and qualitative homogeneity from one harvest to the next. Degummed Hemp Fiber is processed to remove lignin and pectin, so separated fibers are finer, softer, and more absorbent. Size ranges from ½ inch to 5 inches. Hemp Hurd is derived from the core of the hemp stalks and is also referred to as hemp shives. It looks similar to wood chips. It is porous and absorbent and naturally resistant to mold and bacteria. Raw Long Hemp Fiber is right from the stalk, non-processed, and uncombed with slight separation of fibers. Fibers range from 24 to 72 inches. Combed Hemp Fiber, also known as plumber's hemp, is untwisted and combed. Fiber length ranges from 4-5 inches long.
