The Index of BaSO4 Cement Protective Material

2015/04/23  bmschem

    Barium sulfate has a performance of absorbing X-ray. Barium sulfate cement mortar has larger bulk density and can prevent X-ray. Barite, which is used in ray-shielding mortar and concrete, should contain more than 80% of barium sulfate. Barium cement, mortar and concrete made of barite, are used to shield nuclear reactor and build hospital X-ray shielding construction instead of metal tinplate. It is the prefered high strength ray shielding material for X-ray room, CT room, and industrial radiography protection, nuclear medicine, nuclear industry and so on.

    Here are the physical and chemical indexes of barium sulfate cement protective material.

    Physical index:

Name	Density	Appearance	Moh's hardness
BaSO4 cement protective material	3.9-4.0g/cm3	0.01-0.35cm (granular particle)	2.5-3.5

   

    Chemical index:

Name	Ba	Si	Ca	Pb
BaSO4 cement protective material	75%-80%	5%-7%	2%-3%	8%-10%
