High Purity Boron Nitride For Evaporation Boat

Description EVA

Raw Material


hot bending intensity(normal)


Resistivity(normal temperature)


evaporation rate(1450°C)


heat conductivity(1450°C)




   Vacuum hot pressing - The whole sintering processes are in a vacuum with inert gas protection, ensuring a high temperature sintering environment and the promotion of the product   after the evaporation boat with good chemical stability.Good chemical stability, Excellent thermal shock resistanceability and bending resistance,The molten aluminum is easier to spreading,A good resistance to molten aluminum corrosion, to increase the boat’s life.Its supply of evaporated boat heat resistance (Group MOC) ranges from group1~group8 to 800 to 3600 of its resistance value.
1. Vacuum hot pressing - The whole sintering processes are in a vacuum with inert gas protection, ensuring a high temperature sintering environment and the promotion of the product after the evaporation boat with good chemical stability.

2.As ZGH-2 in a vacuum sintering furnace is used with a hot pressing process , it utilizes a dual compression mode, and will be guaranteed a sintered body of the bulk density of consistency.

3. As ZGH-2 in a vacuum hot pressing sintering furnace is used for the entire process with automatic control and digital display, the new ceramic composite boat has better physical performance.
4.As our new generation of ceramic composite boat takes the optimized four components of synthetic structure, instead of the usual 2 and 3 structures, Our product contains the  advantages as follows.

   ---Increased evaporation boat thermail shock resistance and flecural strength , ease of material from the different thermal expansion coefficients of variance of the boat therefore avoiding the evaporation of variance of the boat, which in turn prevents the evaporation operating under high-temperature due to heat build up caused by stress fracture .

   ---Enhanced evaporation of metal boat on the humid , aluminium easy solution to the entire surface through of the boat , raising the evaporation efficiency.

   ---Increased evaporation boat solution, corrosion resistant aluminum

Product Effects EVA


Evaporation boat is made of boron nitride raw material according to the user's requirements to cut into different sizes and in the above ground grinding out the relevant size of the groove, the shape of the gray stripe inside the groove.The use of the groove is in vacuum coating, when the temperature reaches 1500 degrees C or so, the aluminum wire while evaporation, liquefied aluminum wire that is filled in the groove in the groove, not the outflow.Boron nitride evaporating boat is at present the most advanced vacuum aluminum industry of evaporimeter and has long service life, vapor deposition uniform, stable performance, easy to use, in the packaging film, color picture tube, appliances and other industries are widely used, has been fully replaced the graphite crucible, such as the older generation of products. The evaporation boats has good chemical stability,excellent thermal shock resistanceability and bending resistance and  molten aluminum is easier to spreading.A good resistance to molten aluminum corrosion, to increase the boat’s life.
