talc for ceramic

1.Talcum powder has some excellent physical and chemical properties,such as the lubricity, fire resistance, acid resistance, insulation, high melting point, good covering power and soft, good luster, strong adsorption force and etc. 2.Talc has the advantage of high whiteness, uniform granularity and strong dispersibility. 3.Talc can improve the rigidity of products, reduce shrinkage rate,in hollow products. 4.Talc can prevents high temperature creep. 5.Talc lends whiteness to plastics and serves as a good filler.

1.Talc lends whiteness to plastics and serves as a good filler. 2.In ceramics, talc allows firing temperatures to be reduced and also gives ceramics better thermal expansion. 3.Talc can corrosion resistance. 4.Talc has high dimensional stability and chemical stability. 5.Talc's whiteness is enhanced after calcination.

1.Talc can bend modulus and tensile yield strength of products. 2.Talc can resistant to high temperature and color changing. 3.Talc lends whiteness to plastics and serves as a good filler. 4.In ceramics, talc allows firing temperatures to be reduced and also gives ceramics better thermal expansion. 5.Talc can reduce shrinkage.
