Insulated heat sink black ZrO2 Zirconia Ceramic resistor substrate
sheet chip
Zirconium oxide ceramics are white, yellow or gray when containing impurities, and
generally contain HfO 2, which is not easily separated. Pure ZrO2
has three crystal states under normal pressure. The production of zirconia ceramics requires the preparation of high-purity, good dispersion
properties, ultra-fine particles, narrow particle size
distribution, zirconia ultrafine powder preparation methods,
zirconia purification mainly chlorination and thermal
decomposition, alkali metal Oxidative decomposition method, lime
melting method, plasma arc method, precipitation method, colloid
method, hydrolysis method, spray pyrolysis etc.
We can produce it according to your drawing.
