Barium Sulfate Sand

Production Introduction

Barium sulfate sand, also known as barite sand or radiation shielding coating, is a key ingredient in barium sulfate mortar. It is manufactured through both calcination and advanced chemical precipitation techniques. The precipitated barium sulfate is produced using leading domestic chemical precipitation technology, resulting in superior physical properties, minimal mechanical impurities, and uniform particle size. It typically appears as an amorphous white powder or paste.

Product Details

Molecular Formula & Appearance

Naturally occurring as the mineral barite, its molecular formula is BaSO₄. Pure barium sulfate is white and glossy, though depending on the presence of impurities, it may also appear light gray, pink, or yellowish. High-quality crystalized forms can even appear transparent.

Product Features

Outstanding Performance

Barium sulfate sand offers high purity, fine particle size with uniform distribution, excellent acid resistance, thermal stability, high whiteness, and chemical inertness. It has a high refractive index, is easily dispersible, and provides strong radiation absorption, making it ideal for industrial and medical radiation protection applications.

Radiation Shielding Mechanism

The key to its shielding ability lies in barium (Ba) – a heavy metal with a large atomic nucleus. When harmful radiation such as X-rays or gamma rays strikes the barium atoms, the energy is absorbed by the nucleus, effectively preventing the radiation from penetrating.

Application Scenarios

Industrial Uses

Paints, Coatings & Inks: Used as an extender pigment in a wide range of coatings and ink products

Plastics, Rubber, Ceramics & Friction Materials: Widely applied as a filler to enhance heat resistance, aging resistance, and environmental safety of plastic products. Advanced forms like modified ultrafine barium sulfate or high-gloss barite are used in transparent plastic films to reduce cost while maintaining clarity and flexibility

Other Applications:

In drainage pipes, speakers, and appliances for sound insulation

In appliance housings for glossy finish, color retention, scratch resistance, and dimensional stability

As a clarifying agent in glassmaking, helping with defoaming and gloss enhancement

Medical & Radiation Protection Uses

High-Energy Radiation Shielding: Commonly used in X-ray rooms, CT rooms, radiology departments, nuclear medicine, dental imaging, and radiation therapy rooms, offering superior protection due to its high density and radiation absorption capacity

Protective Coatings: Can be mixed with cement in a 4:1 ratio and directly applied to walls and ceilings for efficient radiation containment in control rooms and accelerator facilities
