XATGE ZnO Blocks with MOV glasses

TGE offers a selection of glasses suitable for use as insulating coatings on Metal Oxide Varistors (ZnO “blocks”). TGE offers powders sized for wet application by dipping, rolling or spraying as well as application by dry electrostatic techniques. Typical firing temperatures are 550°C, resulting in pore-free insulating coatings of suitable toughness to withstand potential damage due to lapping of the block ends prior to metallization. Along with PbO-containing glass options, lead-free versions are also available. If lead-free MOV glasses are of interest, ask for our industrial evaluation report for TGE Glass V1467. Our glasses are melted in platinum lined vessels ensuring consistency of physical properties and preventing unwanted impurities. Glass powders are custom milled to your particle size specifications and can be co-milled with additives to increase surface roughness for handling purposes.

Being an ISO 9001-2008 accredited manufacturer and exporter in the market, we put froth a dependable, durable and remarkable range of  ZnO Blocks. In addition to this, our widely appreciated range is made keeping in mind the exact requirements of the industry. As an outcome, it is extensively in demand nowadays. Besides, by using authentic raw material, we gain appreciation for ZnO Blocks from the masses. As per the requirements of the domain, we deliver the product right on time. 

Zinc Oxide blocks

Nano-block body,ZnO varistor refined grains make the material easy to cause transgranular fracture, will help improve the toughness; grain refinement contributes to slip between the grains, the material has plastic behavior; grain refinement the strength of the ceramic material can also greatly increased [6,7]. Currently nano Sintering more are ZrO2, AI2O3, TiO2 [8,9]. Semiconductor nano-ZnO low-density bulk impedance spectroscopy has been reported [10]. But during sintering of nano Zinc Oxide blocks nanocrystals growth it has not been reported. Studied law during sintering grain growth of ZnO 20nm average particle size of paper as the raw material, the application of grain growth phenomenological theory of kinetic equations to determine the index of grain growth kinetics and the apparent activation energy, and with the rough sintered polycrystalline material was compared, we discussed the mechanism of nano xatge MOV sintered. It laid the foundation for the sintering and application of semiconductor material nanometer ZnO.
