Grade 1 premium silica

Grade 1 premium silica – High-grade silica sand is an essential raw material in the world’s industrial development, particularly in the specialised glass, photo-voltaic panels, and many other industries. High-grade silica sand contains a high portion of silica (over 98% SiO₂) and is used for applications other than construction aggregates.

What are the grades of silica sand?

Silica Sand Grades | The grades range from coarse (60 grit) to very fine (8000 grit). There are various grades of sand, which is determined by the type of rock that it is made up of. Coarse sand, for example, is made up of larger particles than fine sand, which is made up of smaller particles.

How to identify silica sand?

What Is Silica Sand & How Is It Different From Regular Sand? In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as what’s often called ‘regular’ sand.

What are the two types of silica?

Silica is divided into two main groups, crystalline silica and amorphous silica (non-crystalline silica). The most common type of crystalline silica is quartz. Other types also exist, but they are less common. Silica compounds are found throughout the environment in rocks, sand, clay, soil, air, and water.

Is sand 100% silica?

Though normal sand composition consists of silica (Si02) it is not 100% silica. It contains lots of other minerals other than silica whereas silica sand consists of 100% pure silica. Silica sand is used as standard sand to test the grade of cement. silica (quartz) is very rarely a sole component of sand.

What is the silica rule?

The final rule lowers the permissible exposure limit of respirable crystalline silica to 50 micrograms per cubic meter of air for a full-shift exposure, calculated as an 8-hour time-weighted average.

Is silica safe in water?

Based on the data analyzed for Longview’s water, no adverse health effects are expected from silica, even at the maximum concentration measured. The maximum silica concentration in water is equivalent to 9.2 mg silica per 100 g (about 3.5 oz) of water, less than the amount found in dried fruits and breakfast cereals.

Is silica harmful to humans?

Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease


What is the difference between 20 and 30 silica sand?

The number 20 refers to the size of the grains, which are between 0.45mm and 0.55mm in diameter. 20/40 Silica Sand has a wider range of grain sizes, between 0.45mm and 0.85mm. It’s more versatile and suitable for different types of filters. 30/50 Silica Sand has larger grains, between 0.6mm and 1.2mm in diameter.


What is high purity silica sand?

Silica, SiO₂, is non-combustible, odorless, and colorless (or white) in crystal form. High-purity silica sand is a major industrial commodity since it is almost entirely composed of silica. Silica sand products are marketed in various grades, including extremely fine flours.


Is silica good for skin?

As silica improves collagen production, it is responsible for forming and maintaining healthy skin, muscles, ligaments, hair, nails and skin. It supports vein, artery and heart health and can lower cholesterol levels.
