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. This page gives easy access to our ceramic crucible sizes data for each product shape and type.

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. Our crucibles and refractory products are available individually or in discounted pack sizes of 5 or 10. Volume discounts are available for larger orders.

Our products are used for a range of scientific applications, their are a wide range of ceramic crucible sizes and shapes. Our main materials are Alumina (Aluminium Oxide) and Zirconia (Zirconium Dioxide), you will find the bulk of our products are made from these materials as they are dense, durable, high purity ceramics with good resistance to thermal shock, can be used at extreme temperatures up to 1800°c and 2200°c respectively.
