Mixed Grade Bubble Alumina Introduction

The following is the introduction to Mixed Grade Bubble Alumina. alumina bubble has the characteristics of lightweight, closed holes and high-temperature resistance. Industry alumina powder melting through the electric arc furnace, blowing and instantaneously cooling in air. It is used to produce lightweight insulating refractories where the prime requirements are low thermal conductivity and high-temperature properties. Alumina Bubble is also used effectively for loose-fill refractories, low density, high insulation refractories castable, or concrete, or to produce ceramic bodies useful in applications up to 1800°C. Welcome to contact us to exchange what is Mixed Grade Bubble Alumina meaning? and look forward to your information.

What’s lead time for bulk order?

1)for 5~25 tons, it takes around 10~15days. 2)For 26~200 tons,20-40days We will try to deliver it with the promise of quality guarantee as soon as possible

What is the shelf life of fused aluminum oxide?

fused aluminum oxide products do not have a known shelf life. As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely

What is a mesh vs. Grit size?

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through, then that sieve would be called a 10 mesh sieve. Typical sieve

What is melting vs. Sintering?

When processing minerals in a furnace, materials can either be melted or sintered.  When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process creating uniformity in the chemistry throughout the entire batch. The sinerting process

What is your terms of payment?

T/T 30% as deposit, and 70% before delivery. We’ll show you the photos of the products and packages .before you pay the balance.

How about your delivery time?
