Recursos de design

As chapas de cerâmica ultrafina de nitreto de silício, também conhecidas como separadores de cerâmica ultrafina ou chapas de nitreto de silício isolantes resistentes à corrosão e de alta temperatura, são uma 

Solução de material avançada projetada para ambientes hostis e de alta temperatura. Essas folhas combinam as excelentes propriedades físicas e químicas de 

Nitreto de silício, fornecendo uma escolha de material ideal para uma variedade de aplicações industriais.


Design ultrafino

Este projeto não apenas reduz o peso dos materiais, mas também permite o uso eficiente em espaços compactos, melhorando a flexibilidade do projeto do equipamento e a eficiência geral.



Alta resistência mecânica e dureza

A alta dureza (1500 Hv0,5) e módulo elástico (290 GPa) do nitreto de silício garantem que a estrutura mantenha sua integridade e estabilidade em condições extremas.


Excelentes propriedades térmicas

Seu baixo coeficiente de expansão térmica (3,110-6 / glass) permite que ele permaneça estável em ambientes com mudanças drásticas de temperatura, tornando-o adequado para 

Use como forro 
Para permutadores de calor e fornos de alta temperatura.


Estabilidade química e resistência à corrosão

O nitreto de silício exibe uma resistência extremamente alta a uma variedade de produtos químicos, tornando-o adequado para ambientes de processamento químico.

Áreas de aplicação

Trocadores de Calor

Utilizando sua alta condutividade térmica e estabilidade térmica, eles são usados como divisórias em trocadores de calor para melhorar a eficiência energética e o gerenciamento térmico 

Desempenho.


Forro da câmara de combustão

Usado em ambientes de alta temperatura, como câmaras de combustão, fornece resistência ao calor e proteção, prolongando a vida útil do equipamento.


Fabricação de semicondutores

Na fabricação de semicondutores, especialmente ao lidar com processos de alta temperatura, ele é usado para proteger e isolar componentes sensíveis de 

Danos térmicos e 
Corrosão química.
