Please handle them carefully and avoid collision during unpacking, transportation,&handling and cleaning2.)Check whether any micro-cracks exist before using alumina products. Products with micro-cracks should not be used.3.)Alumina products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them. If dry crucibles by placing in a dryer or oven, make sure that the dry process goes slowly.4.)Do not load too many materials in alumina crucibles, which can increase the possibility of uneven heating.5.)Alumina crucibles are sensitive to thermal shock. Try to warm up the furnace chamber slowly. A heating rate of 150&C/hour is recommended for the first 1-1.5 hours so that the crucibles can be evenly heated to reduce the impact of thermal shock. It usually takes about 3 hours to increase to high temperature.Crucibles with different shape and various kinds and specifications can be provided by our company.&About the pictures show:&Packaging & Shipping&Polythene-foamed sheet bag and wooden case and wooden pallet or pack as customer&s requirements.Our Services&You can contact our trade manager at any time.
