Specifications:#1(Gold and silver, Five holes)Bulk density ≥1.82 g/cm3Electric resistivity ≥9 μ Ω mBending strength ≥45 MpaResist compression ≥65 MpaAsh ≤0.1 %Particle ≤43 um（0.043 mm）Material: Molded of high-purity graphiteSize: 7.2 x5.7 x 1.2cm（L x W x H）
Features:∙ Well thermal stability : according to the using conditions of graphite crucible snap heat and cold;∙ Well corrosion resistance, impact resistance performance, to ensure the reliability of product quality;∙ Well resistance to strong acid, strong alkali;∙ Good heat transfer performance of graphite crucible: for greatly shorten the melting time and save energy;∙ Ash content less than 0.1% , to ensure the precious metals in smelting is not contaminated;∙ In high-temperature using process, it got small thermal expansion coefficient;∙ And certain strain resistance to the thermal shock, quenching;∙ Long service life.
Using Tips:∙ Stored in dry place, do not get it wet∙ after drying the crucible , don't make it touch with water.∙ Be careful not to give a mechanical impact force, not from a fall or impact.
