ʻenehana hana o ka pālolo taphole:

Hiki ke hoʻokaʻawale ʻia ke ʻano o ka pālolo taphole anhydrous i ʻelua ʻāpana - refractory aggregate a me binder. ʻO ka refractory aggregate e pili ana i ka refractory maka mea e like me corundum, mullite, coke gem a me nā mea i hoʻololi ʻia e like me ka coke a me ka mika. ʻO ka mea paʻa ka wai a i ʻole ka tar pitch a me ka resin phenolic a me nā mea kūlohelohe ʻē aʻe, akā hui pū ʻia me SiC, Si3N4, nā mea hoʻonui a me nā mea hoʻohui. Hoʻohui ʻia e like me ka nui a me ke kaumaha o ka matrix, i ka hui pū ʻana o ka mea hoʻopaʻa i loaʻa iā ia kahi plasticity, i hiki ke hoʻokuʻu ʻia ka pūkuniahi lepo i loko o ka waha hao e ālai i ka metala wela.
