Talc Embolism: Detection of Talc Deposition in Lungs
2016The implemented method is used to enhance and segment the medical image. Here Contrast limited adaptive Histogram Equalization (CLAHE) enhancement techniques is used to enhance the medical images, and Morphological segmentation is used to segment the Enhanced medical image.

Talc–serpentine interactions and implications for talc depression
Minerals Engineering, 2012Abstract The interactions of serpentine with talc and implications for talc depression by carboxymethyl cellulose (CMC) have been investigated through flotation tests, sedimentation tests and zeta potential measurements. Talc is a hydrophobic mineral and CMC is effective for talc depression.

A young woman with a history of drug abuse rapidly developed cor pulmonale, restrictive pulmonary defect, low diffusion capacity, and a suggestion of left ventricular dysfunction. She died from complications after a lung biopsy. Microscopic examination showed talc granulomas and arteritis.

To the Editor.— Cramer and co-workers 1 recently reported observing an association between talc use and risk of ovarian cancer. We therefore examined data on talc use that two of us (L.M. and L.P.L.) had collected as part of a case-control interview studyof epithelial ovarian cancer conducted from 1974 to 1977 in the Washington, DC, area.

Respirable talc powder (RTP) is a complex mineral mixture of talc along with accessory minerals, including tremolite, anthophyllite, quartz, magnesite, dolomite, antigorite, lizardite, and chlorite. The industrial mining, milling, and processing of talc ore is associated with elevated incidences of fibrotic and neoplastic diseases, which are also seen ...

A Structural Study of Talc and Talc‐Tremolite Relations
Journal of the American Ceramic Society, 1960About forty specimens of talc have been examined by X‐ray powder methods. Variations in the degree of crystallinity of the mineral have been observed, but no evidence has been obtained for polymorphic structural varieties. Single‐crystal data have confirmed the two‐layer mono‐clinic cell.

Preparation of dehydroxylated and delaminated talc: Meta-talc
Ceramics International, 2013Abstract The roentgen-amorphous delaminated and dehydroxylated phase was prepared applying intensive milling procedure and subsequent thermal treatment of talc. Due to the similarity in properties and in thermal behavior of this material with roentgen-amorphous delaminated and dehydroxylated kaolinite phase, i.e.

AbstractThree talcs, representative of low, medium, and high CaO content, were used in preparing twenty‐four bodies which were heated at four temperatures. The products ranged from the highly porous earthenware type to porcelain, and test results indicate some possibilities and limitations which the white‐ware industry may expect of white‐ware bodies ...

Talc is a hydrated magnesium silicate produced by the metamorphosis of dolomite and quartzose rocks or by the hydrothermal alteration of ultramafic and mafic rocks. As the changes are rarely complete and uniform, the rocks usually contain one or more other minerals. In pure form it is the softest of minerals.
