Almath Crucibles offer a variety of alumina products, including Alumina Crucibles, alumina tubes and alumina technical ceramics. Our M6 Nuts and Bolts have a maximum operating temperature of 1800°C, making them ideal for high temperature applications.
Our high purity alumina (Al2O3 content > 99%) ceramics are purpose built to perform across a wide range of high temperature applications. We use recrystallized alumina in the production of our crucibles as the material offers impressive thermal shock resistance, this is due to the larger grain size (up to 200mm is advantageous).
Our high purity alumina shows considerable resistance to chemical attack due to the lack of glassy phases that tend to determine corrosion resistance. M6 Nuts & Bolts are available individually or in discounted pack sizes. Volume discounts are available for larger orders.
The electrical and dielectrical properties of the material generally improve with increased purity. Electrical resistance is greatest and dielectrical loss factor is lowest in materials of highest alumina content.
High purity Alumina produces a dense and essentially single-phase ceramic on sintering. Grain growth during sintering can be controlled by small additions of MgO up to 0.05%. Our product usually contains a small amount of closed porosity but this can be kept below 0.5% using modern firing techniques.
Almath is a Newmarket, Suffolk based leading British manufacturer and global exporter of Alumina crucibles and technical ceramic refractory products. We specialize in high purity alumina and zirconia crucibles and hold a wide range of items in stock for speedy delivery. We also offer a range of other ceramic materials, we can design bespoke products with our in house drafts team, we offer precision machined technical ceramics parts to extremely tight tolerances alongside the more everyday use furnace ware.
