Henan Hydray International Trading produces the purest colorless type IIa diamonds, but for micro and power electronics we are able to add the necessary concentration of boron in the synthesis process to obtain better material conductivity (types IIb and IIa+IIb) used in electro-chemical industries.

Achieved results in collaboration with European partners have shown that chemical stability, conductivity and thermal shock resistance of diamonds differ them from other materials and creates a high demand in many electro-chemical sectors of industry as a semiconductor component, key element in diodes, transistors and thyristors, electrode in electrolytes, sensors, integral component in medical and UHF equipment.
