Refworld is the leading source of information necessary for taking quality decisions on refugee status. Refworld contains a vast collection of reports relating to situations in countries of origin, policy documents and positions, and documents relating to international and national legal frameworks. The information has been carefully selected Because talc is very soft (1 on MOHS hardness scale), it causes only minimal abrasion to process and application equipment. It disperses readily in both aqueous and solvent-based paints. Talc having a surface area greater then 12 m2/g is used for gloss control when an exact degree of Sheen or luster is required.Talc (Soapstone) Eshal Industries

The Surprising Benefits of Talc Powder for Refractory
Refractory Uses of Talcum Powder. 1. Enhancing Thermal Insulation: Talc powder has excellent thermal insulation properties, which makes it a perfect material for use in refractories. Adding a small amount of talc powder to refractory formulations creates a barrier between the hot core and the casing, while also preventing heat loss.The techniques used in this process were thermogravimetry (TG), X-ray fluorescence (XRF), X-ray diffraction (XRD) and CieLab colorimetry. Experimental results show that the pyrometallurgical process of chlorination is an efficient method for removing Fe 2 O 3 from talc, by volatilizing it as FeCl 3.
