It is processed from natural minerals. All data are approximate,
and the tolerance depends on production and output. This is only a
descriptive feature and does not represent any guarantee of
specific characteristics. There may be coarse particles. Users are
also requested to jointly test their relevant stability, if
necessary. We can provide more experience in tolerance and
technology. The sales volume depends on the sales and delivery
conditions.
