When choosing talc, at least the "four degrees" of talc itself should be considered, namely: purity, whiteness, flakeness and fineness. Generally speaking, in order to evaluate the quality of talc products, at least the above four factors should be considered. Judging the quality by a single indicator may be incomplete. If someone judges the quality of talc only based on the average particle size, it is very controversial.

When choosing talc powder, you should focus on the "four degrees" of talc: purity, whiteness, flakeness and fineness. These four factors are the basic indicators for evaluating the quality of talc powder. It is difficult to comprehensively judge the quality of talc based on a single indicator. For example, there is considerable controversy over the way to evaluate the quality of talc powder based solely on average particle size.

The application of talcum powder in textiles has many functions, which are mainly reflected in the following aspects:

By adjusting the amount of Talc for ceramics, a variety of performance and effects can be achieved in ceramic products to meet different needs.

Talc for the cosmetics industry used in cosmetics has the following characteristics: it is rich in silicon and can block infrared rays, thereby improving the sun protection and anti-infrared performance of cosmetics.

In general, talc plays an important role in the papermaking industry with its unique hydrophobic properties. How to make good use of the characteristics of talc while maximizing its strengths and avoiding its weaknesses still needs to be explored.

Talc powder provides effective solutions to multiple technical problems in the pharmaceutical preparation process by virtue of its unique functions of hydrophilicity, anti-stickiness and reducing hygroscopicity in pharmaceutical excipients. These characteristics not only improve the processing performance of drugs, but also improve the stability and taking effects of drugs, bringing significant benefits to preparation development and production.

The properties of ultrafine talc are that it is a natural hydrated magnesium silicate mineral. It is inert to most chemical reagents, does not decompose in contact with acid, is a poor conductor of electricity, has low thermal conductivity and high resistance to thermal shock, and does not decompose even when heated to 900°C. These excellent properties of talc make it a very good filler.

Talcum powder can give the coating excellent storage stability and heat resistance.

Talc powder is added to waterborne wood coatings mainly to take advantage of its low cost, excellent filling and good sanding performance. However, the amount of talc powder added needs to be reasonably controlled.
